bed is a common equipment for processing revolving parts and threads. At present, in China’s small and medium-sized processing plants, often the coexistence of CNC lathes and ordinary lathes. When machining, operators will choose whether to use numerically controlled lathes or ordinary lathes according to the requirements of different parts.
    for example, high rotary parts are required; the requirements mentioned here include precision requirements and surface roughness requirements. Because the CNC lathe is far from the ordinary lathe in the manufacturing and the precision of the tool, the precision of compensation and the rigidity of the machine tool, it is necessary to process the parts with high precision on the CNC lathe. Especially for the parts with high requirements for the busbar straightness, roundness and cylindricity, the turning movement of the CNC lathe has passed the high precision interpolation operation and the servo drive, so the machining precision can be realized well and the precision requirements of the parts can be met.

    numerical control lathes not only have good rigidity and manufacturing precision, but also the constant cutting speed is very good, and this characteristic is helpful to reduce the roughness of the workpiece surface. Because the speed of ordinary lathe cannot be kept constant, the roughness of the end face is not consistent. With CNC lathe, the cutting speed is constant at the best linear speed, so that the parts processed are not only of low roughness, but also can be kept consistent.

    in addition, there are some ultra precision and ultra-low surface roughness parts, such as the multi surface reflector of the laser printer, the lens of the rotary drum, the camera and other optical equipment of the copier, as long as it can be processed on a high precision CNC lathe with precision in the order of micron magnitude.
