Large Heavy Duty CNC Turning and Grinding Lathe Machine
For Machining Vessel Propeller Shaft, Cylinders, Marine Shaft, Tire Mold, Railway Parts, Wheel Hub Turbine, Flange, etc.
**1. Outstanding Features:**
All components of the machine are imported from renowned international brands, such as FANUC or SIMENS control systems, Schneider electrical systems, Japanese bearings, ABB motors, transmission boxes, and gear boxes. Our company was established in 1969 as a military enterprise and has over 50 years of experience. We specialize in re-designing and manufacturing customized lathe machines based on your specific requirements.
This series of lathes offers both turning and grinding functions, making it suitable for CNC machining centers. It helps save time and improve efficiency for parts that require turning and milling.
1) **Heavy Load Capacity:** Advanced computational technologies and optimized finite element analysis are used, with materials selected to meet design requirements.
2) **High Rigidity, Stability, and Precision Maintenance:** All castings are made of high-strength meehanite HT250, ideal for heavy cutting. Large castings undergo annealing and vibration aging to eliminate internal stress, enhancing overall precision and geometric accuracy.
3) **One-Piece Meehanite Structure:** This enhances wear resistance and vibration resistance, ensuring structural stability and long-term quality. The cross-shaped base and rectangular bearing structure provide excellent stability.
4) **Fixed Heavy Cutting Structure:** The lathe bed includes rectangular hard rails tested by high-frequency heat treatment and precision surface grinding (straightness < 0.05mm).
5) **Turcite-B on Sliding Surfaces:** Increases rail smoothness and wear resistance. The widened hard rail design ensures stability for heavy cutting.
6) **Headstock Design:** Made of high-strength keel rib with a special cage shape, providing accurate driving and greater torque.
7) **Main Shaft Technology:** Incorporates German AM technology, using chrome-molybdenum alloy. After rough/finish machining, carbonization, aging, and precision grinding, the main shaft demonstrates high precision, rigidity, and deformation resistance. Dynamic balance testing is performed after assembly, and independent lubrication enhances headstock stability.
8) **Standard 4-Knife Library:** Mounted on a turret for precision turning. Customized cutting tool structures can also be configured.
9) **Tailstock Design:** Composed of two parts: the upper includes a sleeve moving mechanism, spindle assembly, and centerline adjustment; the lower includes a fast-moving motor and locking mechanism. High-precision radial clearance-adjustable double-row cylindrical roller bearings ensure high-precision rotation.
10) **CMM Inspection:** Critical machine components are strictly inspected using advanced CMM to ensure quality and precision.
**Our Principle:** Maximize Customer Profitability at Minimum Investment Cost.
**Application:** This series of CNC horizontal lathes can process non-ferrous metals like various structural steels, cast steels, and irons, as well as external/internal cylindrical, conical, and spherical surfaces, threads of non-metallic materials, and curved rotary surfaces. It also supports constant speed cutting. With both turning and milling functions, it allows one-time machining, reducing clamping times and improving efficiency.
