CNC machine tools is a typical representative of mechatronic products, although its mechanical structure is similar with general machine tools,

But it is not general machine tools. Compared with the general machine tool,CNC machine tool has improvement on its structure,such as:

1 Main transmission device adopts stepless speed change or stepless speed change mode.CNC Lathe Machine can control speed and change direction of spindle by program.Main drive has a wide speed range.Some CNC machine tools has adopted compact structure,excellent performance of the spindle.

2 In the feed transmission, ball screwless transmission and the gapless gear transmission are widely used. By using plastic-surface guideway or

hydrostatic guideway to reduce friction force and improve the transmission precision.

3 Bed, column, beams and other major support parts use a reasonable cross - sectional shape and take some measures to compensate deformation,making Lathe Machine has high structural stiffness.

4 The machining center is equipped with a magazine and an automatic tool changer for multi-step and multi-faceted machining, greatly improving the productivity.
