· China Chemical's 7.7 billion US share stake in Pirelli tires approved by the European Union
Recently, the EU anti-monopoly regulator announced that the EU has approved China Chemical to invest 7.7 billion US dollars in the Italian tire manufacturer Pirelli. The European Commission said that after the completion of the transaction, Pirelli's market share is expected to grow at a slower rate, and the two companies have fewer cross-cutting businesses and will not create a monopoly. On March 23, China National Chemical Corporation issued a statement saying that it will acquire a 26.2% stake in Pirelli, the world's fifth-largest tire supplier, through China Chemical Rubber Corporation, and the transaction amount will reach 7.7 billion US dollars. China Chemical will become the largest shareholder of Pirelli. The merger of the two companies is expected to form the world's largest rubber tire company. In 2014, China Chemical's global sales revenue was US$39.69 billion, and Pirelli's 2014 sales revenue was US$7.31 billion. After the merger of the two companies, it is expected to become the world's largest rubber tire company with an annual income of 47 billion US dollars.
1.Dahe CNC Machine Co., Ltd is
the earliest manufacturer for Honing Machine in China. It is the biggest
manufacturer for honing machine with high technical, more model and high
quality. In order to develop CNC Honing Machine, put in to more money and
effort. The [Ningxia CNC Honing Machine Academician Workstation" and [Combined
with Engineering Laboratory of state and local" is set up. It is to undertake
the state major project of high precision honing machine since 2009. The state
major projects are [high precision honing machine", [CNC honing machine for
marine high power diesel engine" and [car connecting" to produce. It is to
undertake the project of producing and research on equipment of high-silicon
aluminum alloy cylinder in 2014. Products are used for automobile, motorcycles,
air-pump, brake disc, cylinder sleeve, gear inside hole, hydraulic parts, kinds
of cylinder etc. It is only one to supply full closed spindle reciprocation
movement, full closed loop of expansion and contraction pressure feed of honing
machine in China.
And also only one reach the level of Germany CNC honing machine
(1)2MK2218x50YS series and 2MK2215X25YS CNC Vertical Honing Machine is a
new kind of CNC honing machine which is designed and produced by our company
according the national science and technology major special project. A new CNC
control system of honing machine spindle reciprocation is designed by us. It is
consist of GSK control system and our special control module and obtained 8
patents of state. The max. spindle
accelerated speed of the machine reach 2.5g.
The control system of the machine can control 5 axis output. The first axis can
control spindle reciprocation move, that is, servo motor drive servo hydraulic
valve, to get high reciprocation move and high accelerated speed, to control high
accuracy of position and short stroke honing; The second axis can control servo
motor to drive spindle rotary with stepless. The first and second axis linkage
can get any honing cross-hatch angle; The third axis can control CNC worktable
to get high accuracy position; Other two axis can control the pressure of rough
and finish honing. This machine is equipped double feeding device,
auto-measuring system to get plateau honing cross hatch. The module design is
selected by the machine. In order to satisfy different customer, we will supply
kinds of collocation from high, middle and low. It is suitable for honing kinds
of automobile cylinder, cylinder sleeve through hole and blind hole which are high
lower than 500 mm.
It can be used alone and connecting with production line.
