The multifunctional CNC lathe of Dalian Mingcheng Electromechanical Equipment Co., Ltd. uses a DC or AC main shaft control unit to drive the main shaft, and performs stepless speed change according to control instructions. There is no need to use multi-stage gear pairs to change the main shaft. In order to expand the range of speed change, a first-stage gear pair is generally used to realize stepless speed regulation. Even so, the structure in the headbox is much simpler than traditional lathes. Another structural feature of CNC lathes is their high rigidity, which is to match the high-precision control of the control system in order to adapt to high-precision machining.

Compared with traditional lathes, Dalian Mingcheng Electromechanical Equipment Co., Ltd. CNC lathes generally use inlaid steel guide rails, so that the accuracy of the machine tool can be maintained for a longer time and its service life can be extended a lot. Due to the high price of CNC machine tools and the longer life of the control system, the sliding guides of CNC lathes also require good wear resistance. Because the two-direction movement of the CNC lathe tool post is driven by two servo motors, its transmission chain is short. Dalian Mingcheng Electromechanical Equipment Co., Ltd. does not need to use transmission parts such as hanging wheels and light bars, and directly connects the servo motor with the lead screw to drive the movement of the tool post. The servo motor screw can also be connected by a synchronous belt pair or a gear pair.

Dalian Mingcheng Electromechanical Equipment Co., Ltd. CNC lathe tool holder movement generally adopts ball screw pair. The ball screw pair is one of the key mechanical components of the CNC lathe. The rolling bearings installed at both ends of the ball screw are special uranium bearings, and their pressure angle is much larger than the commonly used centripetal thrust ball bearings. This kind of special bearing pair installation is optional, and it is best to pair the bearing when it leaves the factory. In order to be portable, CNC lathes are fully lubricated, and most of them use oil mist automatic lubrication. CNC lathes also have the characteristics of sufficient cooling and tight protection, etc., and are generally in a fully enclosed or semi-enclosed state during automatic operation. CNC lathes are generally equipped with automatic chip removal devices.
