New Trends in the Development of Machine Tool Technology? Review of IMTS2000

In the exhibits of the show coffee 1820, you can see some new developments in the following machine tool technology.

High-speed machining progress from the development of high-speed CNC machining in the early 90s, with the electric spindle, the realization of high spindle speed and the realization of high linear movement speed by linear motor, the main focus should be on the mass production of the car industry and other fields. . The door is the machining center with high spindle speed and high-speed linear feed motion of the leather spindle. It is difficult to realize the spindle speed and high-speed feedability instead of multi-spindle, which is beneficial to the rapid update of the product without reducing the production efficiency. In actual production, some well-known automobile factories, such as Shanghai General Motors Corporation of China, have already replaced the combination machine tools with a production line consisting of high-speed machining centers. The current trend is to continue to expand the scope of similar applications. Some companies do not use linear motors in order to reduce costs. The use of hollow-pass coolant to increase the diameter and increase the lead of the ball screw; Japan Toshiba machinery uses a double-ball screw with a hollow coolant to enhance the transmission stiffness. But no matter what kind of ball screw is used, the maximum movement is not as large as 50. The acceleration is the most important. 5 do one heart, but he, the company's 10 high-speed machining heart, from the use of a frame structure that can make the moving parts smaller, such as winter 1 and pavilion 2, despite the claw wide ball screw, its special axis linear speed It can still be as high as 爿 acceleration.

Another area where point-speed machining is used is high-speed milling or turning of hardened steel with cubic boron nitride tools. This is very profitable for the mold industry. In order to pursue the final high precision, the general hobby has been hardened by a few hardenings in the mold. In the past, the only processing method that can be used to deal with hardened molds is electrical machining. Electric plus. The discharge ablation is micro-chip processing with extremely low efficiency. High-speed milling of hardened steel can be several tens of times more efficient, making it an alternative to electrical machining. Although, for those large molds with deep and narrow grooves with small curvature radius and clear angles, etc., island speed milling is powerless, it is impossible to replace all electrical machining, but high-speed milling can be used for rough semi-finishing. At the end of the work, the mold is still shortened. For a large number of narrow and deep groove molds, Liang Xun and Zhou Yanyou can use electric machining methods. For this reason, electrical processing will never be replaced.

The challenge of high-speed milling of hardened steel to electrical machining has led to the speeding up of electric machining machines. Japan 8, the company in 1999 in 1996, the first in the world to introduce a linear motor to replace the ball screw cutting machine and punching machine also used a linear motor. The linear motor drive with a linear motion speed of 3610.1 replaces the good speed speed port with 1.31. The superiority of the ball screw drive such as the left and right resolution is not reflected in the high speed. The feed property of this foot in the EDM machine is + forward to maintain the discharge gap, and the result is short-circuited back. Since the linear motor greatly improves the transmission rigidity and has a linear thrust of up to 30, it is possible to generate an instantaneous high acceleration and deceleration, forming a high-frequency transient, intermittent shock, and washing away iron filings due to electrical erosion. In this way, the cutting and scouring brush can be dispensed with 1 or 18 devices, which can be directly maintained, and the sparking gap of the small flying can achieve rapid feeding, thereby not only greatly improving the efficiency, but also improving the 40 precision, improving the roughness and solving the problem. In the past, it was difficult to solve the problem of scouring, such as the difficulty of making small holes in small and dense electrode drills, and the inability to perform electrical machining. The aerospace and aerospace industries have traditional applications of high-speed machining. The reason is that the main material is aluminum and aluminum alloy. The parts are often thick. The honorary chairman of the China Machine Tool Industry Association, the China Machine Tool Industry Association, the high-profile thin wall and ribs, the rigidity is very poor, only the cutting force at high speed cutting These rib walls can be machined very small. The latest trend is that these industries have recently adopted large-scale aluminum alloy blanks to make large parts, such as wing fuselage, to replace multiple parts with numerous rivet screws and other coupling methods. In this way, not only expensive assembly man-hours and assembly tooling, but also the strength rigidity and reliability of the components can be improved. Therefore, in this year's 18th, the United States 1 brother Ding 1 and the Italian buckle company have exhibited a special plane with a strict aircraft, the industry's large-scale milling machine models are 1361 and respectively.

Net, 159. This type of machine tool has the following characteristics to improve the spindle speed and power. Because the aircraft industry uses the overall blank hollowing method to machine parts, the cutting cost is huge, the flash, the spindle speed and power increase the space. According to the company, in the past, the owner's shaft speeds of 1501 and 22 were high speed. With the advancement of technology, advanced machine tools have been raised to 4,00 and 40. And their continent 3 has been increased to 60,000rmin and 80kW, that is, reaching new heights, ultra-long special strokes and gantry movement due to wing class Slender parts say the machine axis travels up to a long distance! The 7-axis is only 2,1 allegedly used to machine the wings of the typhoon of the next generation of European fighters. , ah, this machine has a maximum stroke of 46 axes and only 1 2 British 131 company 4 series machine tools have a total length of 100 on both sides. This long stroke can only be that the gantry is often multiple dragons moving and not the workbench. mobile.

The use of linear motors for high-speed linear transmission and the previous aviation industry for large plastic machine tools with oblique, wheel bar or worm bar drive is not the same, also used the ugly line motor = this is to adapt to the spindle super, speed extra power and super long leg The need for 31 machine tools after the use of linear motors, the feed speed of up to 60, fast 100, acceleration knows. According to the 0 company, they are at 1! I said that I had tried to cut thin-walled aircraft parts on the 3rd. It only took 30 minutes. The same part took 3 hours to process in a high-speed milling machine, and 8 hours in a normal CNC milling machine. Full, the power of ultra-high-speed machine tools 133 company launched in 2000, another high-speed large-scale milling machine for the aviation and mold industry, for the bridge layout, also used a linear motor, the most in-feed speed of 60 acceleration up to 0.6, The spindle speed is 2400 and the power of the continent is 4 Jia. It is said that due to the high-speed spindle and the speed feed, the addition time can be reduced by 50, the machine structure is also simplified, and the parts of the machine are reduced by 25, so that it is easy to maintain. To say that the line motor application has been expanded from the original automotive industry, To the processing of electric machining machines, aviation industry and large molds. Not only that, but also the linear stamping machine and the laser sheet cutting machine used in the 18 exhibits. For example, the company's laser cutting machine uses a linear motor with a speed of 15 and an acceleration of 1.3. Machine, such as the company's pool bar products, the linear movement speed reaches 3, so. The probe can make more than 120 contact measurements per minute.

Speeding up another key feature The electric spindle has recently made the following new developments. Ruigong has introduced products with online automatic balancing devices on the parts of the electric spindle. In the case of adding 1 heart, the movement balance including the tool quality is performed every 7 times. It is said that in 20 seconds, the vibration caused by the unbalanced movement of the 8090 can be eliminated.

The Swiss 1 recognized 0 company introduced the electric spindle of the wide hydrostatic bearing, which is said to have a service life of more than 20,000 hours.

In the United States, the company introduced the electric spindle of the hydrostatic bearing as a separate component.

The Swiss AG male fJ is equipped with an axial size monitoring sensor on its electro-spindle components. The electric spindle that can be coupled with the machine tool numerical control system for the axial size permanent magnet synchronous motor has also appeared before the electric spindle rotor can not be cooled, and the rotor of the permanent magnet synchronous motor does not generate heat for the permanent magnet. The synchronous motor of the same power can be smaller than the asynchronous motor, which is beneficial to achieve small size and small power, and can also increase the power density. 6. However, only a few machine tool companies such as the electric spindle company in the development of the pan-tech have not yet supplied the product.

At least one of Europe's well-known electric spindle companies, Switzerland, has been rushing to the US market, and has established a branch office in the United States for sales maintenance and refurbishment. The reason is that the core technology of the electric spindle is precision machining and precision assembly, which requires a high level of skill for workers. These are the strengths of Switzerland and Germany; the rolling bearings have a low life at high speeds. The main form of failure is the loss of precision due to material fatigue. The accuracy of the electric spindle is as radial as 2, and the ability of the axial 1 plant to have no local maintenance refurbishment is impossible to open the market. Some electric spindle companies recommend that users purchase a spare item because the general repair and renovation time is two weeks. In this way, 4 downtimes are minimized.

On the eve, the United States 03; the company introduced a tool holder with automatic balancing to adapt to high speed.

The 5-axis linkage machining was fashionable; the 5-axis linkage and surface machining were combined in this year's 18th, giving people a prominent impression that the 5-axis linkage machine tool is more than before. According to the + complete statistics, there are about 50 units. Appeared, not accidental, the following profound background.

In essence, the processing of 3-dimensional surfaces, 3-axis linkage WMEM 3 is not the best choice in June 2001. In the case of 3-axis linkage, it is difficult to cut with the optimum geometry of the tool. Not only is the efficiency low, but the surface roughness is extremely poor, which often requires heavy manual polishing. Manual polishing can improve the surface roughness and often The geometric accuracy of the surface is lost. For this reason, some companies use subsequent EDM, which not only takes longer than the time but also creates electrodes with complex shapes.

With 5-axis linkage, cutting with the optimum geometry of the tool can be performed by cutting the non-tip portion of the arc portion of the ball-end milling cutter so that not only the coarse sugar content but also the efficiency is greatly improved.

The United States 0 case 0 to 1 company once claimed that the efficiency of the 5-axis linkage machine tool can be equal to two 3-axis linkage machine tools, especially the current popular high-speed milling and hardening process with cubic boron nitride milling cutter, in the case of 5-axis linkage The lower can be more powerful than the 3 axes. Therefore, in general, 5-axis linkage is the best choice for dimensioning surfaces. In the past, due to the following reasons, the wide application of 5-axis linkage has been hindered. The price of the past 5-axis linkage CNC system is extremely high, and it is more than 3 axes. The system is several times higher. Now, the price difference between the two linkage systems is small.

Ultra-low speed and high torque, smooth rotation, has always been a major difficulty in motor drive technology. Therefore, there are only a variety of structural mechanical reducers. With the rapid development of power electronics and microelectronics, especially digital signal processor chips and permanent magnet materials, this major breakthrough has been broken. Recently, Switzerland 1 and the United States introduced a brushless toroidal torque motor with a total of 813, 88 ga. 0, 21. The company once provided a table diameter of 2.5 for a large astronomical telescope, and a thickness of only 4, torque. A toroidal torque servo motor of up to 10, 爿1. Under the condition that the concave rotation speed is as low as 56 days and then turns 1 rotation, it can be rotated extremely smoothly and evenly, which is unthinkable. The company is also using a toroidal torque servo motor with a diameter of 51 and a ring-torque servo motor for the aerospace industry to replace the worm gear pair. The machining accuracy and surface roughness are greatly improved. Currently, the two companies Available in a range of sizes and sizes, the outer diameter range ranges from 12 to 126, 1 torque from up to 18 000. Positioning accuracy is up to 0.5, and repeatability is up to 0.0. The minimum speed can be reached in the near future. The worm gears in the human 0-axis servo drive of the composite turret and the composite spindle head will be replaced by these ring servo torque motors. The worm gear pair of spiral bevel gears will gradually withdraw from the field of CNC machine tools after the spur gear pair. This is a breakthrough change.

In order to accommodate the increase in 5-axis simultaneous machining applications, the US Top 1 101 company now sells the features of the composite spindle head model 544. I bought it and changed the existing 3-axis linkage machine into a 5-axis linkage machine. The composite spindle head uses the 724 taper shank and the company's connector to connect with the existing machine's spindle. The 6-axis range is 5 Axle post-processing software, interested readers can go to the company's website at the teardown 182000 on the 1st 1 stand, exhibiting a 23-type composite spindle head designed and manufactured by De Ding Company. The head adopts parallel and series connection. Rod mechanism. Due to the limitation of the parallel mechanism, the maximum tilt angle of the 23 spindle head is only ±40, so it can only be used for 5-axis linkage, but not for 5-sided machining.

In the past, five-sided processing was performed on large parts. It is realized with a double-column machine and a replaceable coveted and horizontal spindle head attachment head. To this end, in addition to the powerful library, this type of machine tool also has a spindle head library, and the beam is to be used as a spindle ram for the spindle head. The 5-face machining machine exhibited by Japan's new 1 machine in the first 18 is such a structure. This exhibition changed the structure, instead of using the method of exchanging the spindle head, the above-mentioned composite spindle head was used. When the person only locks the shaft at the 0 position, the horizontal plane of the workpiece can be processed. When the shaft is locked at four 90 positions and the 8-axis is locked at the 90. position, a vertical vertical plane can be processed. That is, with such a composite spindle head, 5-way machining can be realized, and since the shaft lock is at an arbitrary angle, it is possible to realize processing of not less than four but more or less than four vertical planes. Qian Xie has mentioned that the composite spindle head can also realize 5-axis simultaneous machining. The 5-sided and 5-axis additions can be realized on the same machine tool, which is another form of composite machining. This is advantageous for the processing of large molds. This kind of machine can also realize the processing of the inclined surface and the inverted cone hole, that is, the big head. 6. There is no such thing as this. On the 15th, in addition to the new Japanese machine, there are many companies exhibiting similar machine tools. The names are all special. Nbsp;3 processing bevel 1 plus, taper hole NC machining to improve the productivity of the machine tool network is not new to the CNC system, but in the past, the understanding of the Internet is to transfer processing programs to the CNC system, especially large-capacity programs to achieve remote diagnosis And remote repair services, etc. On the 152000, Sakamoto Otsuka 0 biliary machine tool company exhibited, 1 Qing Information Technology Plaza, hereinafter referred to as 邝 Square; Japan, 1 also Yamazaki company exhibited ice 61010, 6 resistant intelligent production control center, hereinafter referred to as Yamaguchi The flexible joints of the existing Shenji precision machine exhibited by Seiki Co., Ltd.; the United States 10 machine tool company and the two booths of the exhibition cooperated with the exhibition, the mouth 617, the open factory to open the manufacturing environment, etc., can see that these manufacturers emphasize the networking is progress To improve the productivity of machine tools, Daxie said that only good machine tools and good CNC systems are not enough to adapt to the current fierce market competition. Only when they enter their Ting Square can they win in the competition. Creating value. The rest is time without creating value. They think that it is possible to connect the machine tools to their 0, and it is possible to increase the cutting time from 25 to 65.31. The company says that in order to maximize the utilization of the machine, it needs to be installed in the 1-man interface of its CNC system. The Ethernet communication card is connected to the factory intelligent network.

For example, 4 believes that the machine utilization rate is only 25.

0 programming program editing and trial cut.

The mountain changed in production planning and the new adjustment of the machine tool.

4 report and monitor the number and operation of the machine tool.

For the above five serotonin, the following four software modules are seamlessly integrated.

The best multi-variety parts processing plan is proposed through simulation. When the dispatch is urgently placed, the re-simulation of the change plan is carried out to find the best solution for scheduling, which can not only make a quick response but also cause production confusion, so that the resources are optimized for use. In addition, the module also collects and analyzes the shop floor data so that the tool holder gets the best application and the lowest cost list of tool holders for the bait type workpiece.

Monitor the operation of each machine online and easily monitor it remotely in the office or via the Internet.

Human-computer interactive programming and program optimization, will be referred to as the digital manufacturing solution. The example is shown in 182000. The sample lists three users' satisfactory evaluation of their functions, and they call it a small silver factory in China. The company's 30 machine tools are directly controlled by its 00.

Daxie called its square a large network factory OkumaNetFactory. It means integrating information technology and processing technology. It is believed that only relying on advanced processing technology can not survive in the fierce competition. It must be developed to increase the speed and expand the Taishang 3 phase. In June 2001, the concept of Ting Square was a three-dimensional ball. The center of the ball is CNC, the system. . On the circumference of a sphere on a sphere, a water surface and two straight planes that are nine, each of which distributes six small balls, a sub-machine software module and an Internet portal, these six small balls. Both point to the center of the ball, low-normal, and interactive function of a software module, a large self-made 03001 system MacMan network cattle production management system 01 from the operation of a person skilled database database, 1 〃. Daxie new 0, milk nine, 1 system OSPmerit.com portal to the Internet Dagu believes that today is the era, whether the company can receive the next order, depending on whether its production management system can adapt to the delivery date Short and task-changing requirements are for this purpose. It captures the system; through the intranet, the system monitors the production site and collects on-site data for optimal planning and scheduling. When the production task suddenly changes, it can cause almost no loss, as well as remote diagnosis and maintenance functions; the chip enterprise resource planning function can make the sales information financial accounting and production control, by fundamentally shortening the production cycle and maintaining The ideal inventory is watery and has been greatly reduced to a small purpose. The KCMAC Operators' Skills Database believes that the skills formed through rich experience and intuition are a must. The digitization of these technologies and the sharing of the whole company can achieve high-efficiency and high-quality processing. KCMAC can make these skills fully utilized and become valuable intellectual wealth, which can create new technology, new knowledge and new ideas.

ADMA's new 0,4 plus system instantly converts 3 data into process tools, clearing process cards and adding process paper, enabling parallel machining to shorten production cycles. Optimized machining program with zero operation.

In addition to the above software modules, there are.

OSPrnerit.com Ting Plaza is the gateway to the Internet. Through it to connect with the outside world. By contacting the customer, you can set up a window for each customer, quickly respond to the customer's requirements, and contact the processing equipment tool holder supplier to get the latest information.

The history of the year. For the basis of the system. Using the commercial name of 3, 4.0 and a real-time operating system, the company has 83 public village products, built-in Ethernet communication cartoons to the internal network, organically integrated human-machine and network into the core of the square; The final sample of the 8100 sample states that the system is a strategic material in accordance with the relevant laws of the Japanese government.

The horizontal plane of the ball connects the human 4 and the 0, 61., 01 small balls. , in order to establish an optimized production process to collect data, the ball's coveted plane circumference will connect the machine tool, the person 0 MACOSpmerit small ball, 0 is to make the production efficiency ball another vertical plane also the machine tool 10 and enjoy a database of workers' skills and know-how.

The six 1 small balls have two circular crosses that interact with each other in the center of the ball. They form a square, and the 31-foot-1 of the mouth-finished machine is essentially the same as the square. It is not mentioned here.

The CNC lathes exhibited by the US 6 Machine Tool Show are all equipped with the 01 and 5 companies' 3 plus 7 inch systems, connected by Ethernet lJ servers, and connected to GEFanuc's booth.

In addition to calling the 6 booth. In addition to the benefits of networking, the remote data access function of this machine is also displayed on the 17th stand.

It is said that it is embedded in Ding. Industry 10's Zhihua 7 system combines the flexibility of the hardware and the series based on the application software of the 8 and the control of the machine tool, so that the 1 system becomes the maximum performance improvement to meet the shortest delivery time and the lowest cost. Demand.

The functions installed on the machine tool also include new functions added after connecting to the server via Ethernet, such as obtaining relevant documents related to the machine tool, production juice scheduling and processing of the workpiece; using the workshop programming to play 0010130 for the US 71 professional company 18 company software product software programming, visualization, visualization and forced. 1 machine event monitoring and local hard disk, 标准 标准 standard flash memory card and other hardware.

The entire network leads to the manager general manager and maintenance manager responsible for the production, so that these personnel can keep abreast of the current situation.

The existing old machine tools are also networked. Regardless of whether these machines are equipped, the system that was previously shipped from the factory, or the CNC system of other companies, can be networked by the company. It is said that the method is to use two screws to screw on the Taiwan industry, 0, if it is the company's previous products, you need to add HSSBHiSpeedSeridBus, iM serial bus board. In addition, the company and the world-renowned network equipment manufacturer 060 company, jointly formed the 000 industrial network public cut, undertake any level of network construction work in the industrial sector, from small to large, to a factory and company ball business Networking work. We also found that there are companies specializing in networking CNC, such as eManu Plus 8 from the above introduction of the company's products, we can see that the previous machine tool company only sells machine tools, CNC system companies only sell systems, now some machine tools and systems companies, together The network includes the accompanying software to sell. The reason is that, in the case of a single small batch production machinery industry, this production mode accounts for about 70% of the total output value, and the machine cutting time is only 25, that is, 75 time is not utilized. If you only pay attention to the efficiency of a single system of a single machine, just make an article on 25. Only networking can raise 25 to 65, the point of view. Networking is not an end, but a means to improve production efficiency. This is also a complete set of concepts, but it is a high-level set of processing informationization, and the previous supply of different corpses.

Only networking, no corresponding software modules, can not make a difference, software features are low, it is impossible to increase the cutting time to 65, the importance of software-concentrated knowledge, the aforementioned software module is special, is the company The KCMAC module contains digital worker skills, accumulating and creating new skills, new shackles, etc., and its integration with production management modules, which means that the previous data processing in the transition to knowledge processing, the vast amount of information on the Internet The content is stupid and deep, and it is transformed into a directly usable knowledge, which belongs to the high-level application of computers. It shows that the informationization of the entire manufacturing industry is being processed from low-level data processing to high-level knowledge processing.

Also taking the hardware provided by the professional factory Ryo Electric Co., Ltd., focusing on the development of unique software, and the main focus is on the manufacture of machine tools. Therefore, the main software modules for networking are developed almost exclusively for their own applications. Continuously improved in use. They are full of confidence in their maturity. 3. The supporting software module contains relatively mature first-party software on the market, such as the 0,1 software mentioned above for collecting vehicle data. No matter, the 32-story or the 0-storage 1 system is included, which is called fusion, based on, and embedded to provide excellent conditions for the use of the first software standard hardware interface.

Daxie, the system is the core of the booking square, with Fanl, said to turn its CNC into a high-performance information center. After the networking, the 0 system plays an important role in the machining of the high-level multiplier. The essence of the complete set of equipment from the bottom layer is to build the 01 elbow 3 system from the bottom to the top, so that productivity is not good. It seems worth exploring.

The turning and milling compound machining center has the power to add a power tool holder to the CNC lathe cutter head, and can perform drilling and milling processes to form a turning center. It seems that the power of the milling and so on is too small and the speed is too low to meet the requirements of some complex rotary parts. Therefore, the cutter head is cancelled and replaced with a high-power and high-speed electric spindle. By Ding Tong, only a variety of tools can be installed, like the processing of the heart, the addition of the tool magazine and the mechanical Ding, no matter when the car is turning, the electric spindle is locked, the turn, and the foot-drilling and milling tools are stored in the tool magazine. in. In addition, an axis perpendicular to the y-axis and five axes revolving around the axis are added. Although the tool change time far exceeds the boring center, high-speed and high-power milling and turning can be achieved. Substantially equal to the lathe and the addition of 1 center, called the turning and milling center. At the elbow 182000., 1; 1 company exhibited its 10 series of trolley milling centers.

Milling shaft speeds up to more than 10,000 kW. It plays in a small time in 10 minutes, only after the clamping, through the turning and milling composite process to process the root large diameter whole round bar material out of the crankshaft of the automobile engine. A plurality of planes of the connecting rod journals and the cranks in different spaces are machined by the joint of the one shaft. Of course, this process is too expensive to machine crankshaft materials.

The on-site personnel explained that this method is limited to the trial production of the engine and the special air compressors produced by some single parts, and the main piece of the show is the power of the integrated turning and milling machining. In the manufacturing industry, especially in the aerospace industry, the printing press compressor industry, the number of complex rotary parts is quite large. The machine tool industry is no exception. For example, the cutter head of a CNC lathe is a typical generation of complex rotary parts. 102, the small giant company in China's silver, is equipped with a trolley milling and machining center, accounting for the total number of machine tools. 17. Austria has a stomach 1 company specializing in the production of large-scale model compound Jiading Center. It is said that the order subscribers are mostly from the aerospace ship printing press and other industries that have been running for many years. The parallel and tandem machine tools starting from low-level applications continue to be successful; the parallel machine tool entered the field of turning for the first time and was first exhibited in the world of Xun 8 in 1994 and caused the world. The sensational parallel 6-legged machine tool, also known as the virtual axis machine tool, and the subsequent two-WMEM 3 phase of the global follow-up wave of June 2001, have gradually cooled down worldwide. The two well-known pioneers did not appear after only one or two exhibitions. The other majors in the UK are traditional machine tool companies. The parallel machine tool company only exhibits the parallel machine tool twice after disappearing. This is because the parallel machine tool has a series of difficulties in theory and practice. Hard to solve in the short term. However, only the exclusive Swedish small company, only 103 companies not only participate in the exhibition every international exhibition, 1 and its products have already entered the practical, so far has sold more than 200 sets of shocking performance. Its success is a combination of mountain and mining in parallel and series.

The company's rice rods are named as 1 structure is not a six-bar structure, solving the three degrees of freedom. The other two Xiaoshan degrees use a mature traditional series mechanism to solve the problem of a composite spindle head that can rotate 4 turns. The difficulty is correspondingly greatly reduced.

Starting from low-level applications, gradually accumulate experience and financial resources, and develop from high-level applications from low-level applications where positioning accuracy and speed are not high, such as grinding wheels or milling cutters, burr chamfering oil holes, low precision The press fit 艽 stiffness of the welding internal assembly is much larger than that of the multi-joint robot, so it can be replaced, and the garnish object is easy-to-cut material such as wood plastic aluminum to open the market and apply. Because of its low cost, it is more than enough for these low-level applications. It has quickly received orders from the automotive industry, such as Dingye, and its products have already entered the icon, 3 Volkswagen Reynolds and other famous car factories and such famous ones. The aircraft factory, bearing the above mentioned rough work. From these applications, the company has gained a wealth of experience and economic benefits of four views, supporting the company's progress to high-end applications.

This time, the company exhibited 845 plus center, 8. Its volumetric positioning accuracy reached ±50; for example, the repeat positioning accuracy is ± yang, the two indicators are far from the traditional machine tool, but for parallel machine tools, It has practical value = and its feed rate has reached 90, the acceleration is reached, which is better than the traditional machine tool without linear motor.

The spindle power is 30,45, the maximum speed is 24 3000, 1 leg, and the Swiss company's electric spindle 3,840D CNC system and Heidenhaln's M system are adopted. The machining center has a modular structure. The rod structure component is stored in 0.45.90. The layout may optionally be a horizontal tilt 45 vertical machining core workpiece mounting component is also an optional module. Moreover, within 3 years, the user wants to change the layout of the rod structure components due to the addition of the object, and the company can freely rebuild it on site; the machine tool bracket is made of artificial granules with epoxy resin and granite gravel. , cast and cured. The team seems to be structurally successful, in addition to reducing the number of rods to simplify the structure, but also largely thanks to the central tube in the center of the rod. The central tube of the diameter ancestor not only greatly increases the rigidity of the structure, but also has a built-in measuring system. By measuring the length of the sleeve and the attitude of the center tube, the actual position of the knife in the space can be directly measured, and then the length of the rod is compared. The indirect measurement is solved as compensation for deformation temperature or the like. It is difficult to measure the position of the machine.

Interestingly, the 6 and 8 companies started with only 3 people, and today they only have 30 people. In just 5 or 6 years, they have become the stars of the parallel machine tool industry. The 1608 public website is 1608. Readers interested in 00014 can check out the American branch of Germany, and the inverted branch of the rod parallel mechanism, that is, the spindle and the workpiece are engaged in 2-axis motion, while the cutter is not moving, returning the conversion knife, but does not make any The linear motion vertical lathe, China's conventional force inverted car, the parallel mechanism used in the lathe, is very clever. Flashing, the biggest weakness of the parallel mechanism is that the effective utilization of space is very low. Therefore, the range of movement of the spindle platform should be small, and the lathe is not like the machining center, and the range of movement of the workpiece relative to the tool is originally small. So the shape is compact.

In order to increase the rigidity, such as the two-bar structure using two rods as the root rods, the town is called a three-bar structure. It is similar to the structure of the Tianjin No. 1 Machine Tool Plant. The electric spindle rotates at 800 rpm and the power is 26.48.
