In the transformation of general Lathe Machine into CNC Lathe Machine, how to choose the nc system, servo system is an important parts in modifying the mechanical parts.

In recent years, with the industry requirements for machining products and CNC technology,high precision, high efficiency and low labor intensity has became the mainstream in today's manufacturing industry.

Now, the transformation of machine tools, especially the transformation of ordinary machine tools into economic CNC machine tools, has become an important part of investment in equipment. We should consider some problems described below:

1 servo system selection

Servo system is an important part of CNC machine tools.Its performance

determines the performance of nc machine tools largely. For example, the maximum moving speed, tracking accuracy, positioning accuracy and other important indicators depends on the dynamic and static performance of servo system.

2 CNC system is one of the most critical link in CNC lathe machine.

First, consider the functional requirements of the machine tool to be modified. According to the functional requirements,then choose suitable numerical control system.

Secondly, we must consider the numerical control system manufacturers.

Ususlly, China-made system function is simple, performance is stable.It has a wide use in gereral lathe and milling machine.Some CNC system has already reached the international level.

Thirdly, we must consider the numerical control system and matching parts . If the numerical control system, the motor and the driver's variety is too miscellaneous, it may appear the input and the output signal mismatch after connecting.In addition, if funds are abundant,as far as possible to buy famous manufacturer model series productsto better prevent the failure of electrical components.
