Part of function of machine tool of our country numerical control has developing through two ways at first. It is to specialization accessory production manufacturer produces progress to numerical control accessory, typical product know exactly about sth accuses guide screw of chuck of revolving stage, motivation, ball to wait; 2 it is component of sex of function of form a complete set of research and development of ego of manufacturer of lead plane production, typical product know exactly about sth accuses tool carrier, factory of domestic most lathe experienced this process. The author thinks, specialization the direction that production should be development of accessory of our country numerical control.

Look from technical development, technology of numerical control machine tool develops to high speed, compound, intelligence and environmental protection direction, raised similar requirement to dividing head of revolving stage of numerical control tool carrier, numerical control, numerical control. The aspect is changed in the high speed of numerical control accessory, company of group of accessory of Yantai round-the-world machine tool developed tool carrier of drive of electric machinery of AK36 series servo, main characteristic is to introduce drive of servo electric machinery, hydraulic pressure or baric and loose clamp, dislocation time is adjustable, change time of a knife the most quickly to be 0.15s, reach level of foreign congener product; Rotate speed of revolving stage of numerical control of TK13250M high speed achieves 30r/min; Compound convert tool carrier of AK33 series motivation, use modular design, dynamical cutting tool by drive of servo electric machinery, rotate speed of milling power cutting tool is top can achieve 3000r/min; TK14 series numerical control but bend revolving stage, achieve two axes linkage by drive of two servo electric machinery, form a complete set at machining center of 5 axes linkage. The place on put together is narrated, high speed is changed, compound changed product of numerical control accessory to represent domestic top level, fill home is blank, the development that is lead plane provided safeguard.

Narrow as soon as possible the difference of high-grade accessory

As the development of component of numerical control function, lead plane is older and older to the dependence of functional component. Cong Mou is planted tell on degree, the development level of functional component represented the development level of lead plane, its dependability, advanced sex is highlighted particularly. Development of domestic function component is at present lopsided, integral level and abroad have certain difference.

The product level of component of function of numerical control machine tool is compared with the photograph 10 years ago, had very big rise. Through development of nearly 20 years, the breed of product of tool carrier of numerical control dividing head, numerical control is ceaseless and perfect, main function and dependability have bigger rise. Dividing head of revolving stage of numerical control tool carrier, numerical control, numerical control already can be satisfied in the demand of form a complete set of machine tool of cheap numerical control. But the product of numerical control accessory that is form a complete set of machine tool of high-grade numerical control, with abroad product comparing still has certain difference.
