Selection principle

Preliminary preparation

Determine the technical requirements of typical parts and the batch of processed workpieces. The function that the CNC lathe should have is to prepare in advance, and the prerequisites for reasonable selection of CNC lathes meet the technological requirements of typical parts.

The technical requirements of typical parts are mainly the structural size, processing range and accuracy requirements of the parts. According to the accuracy requirements, that is, the dimensional accuracy, positioning accuracy and surface roughness of the workpiece, the control accuracy of the CNC lathe is selected. Choose according to reliability, which is the guarantee to improve product quality and production efficiency. The reliability of CNC machine tools refers to the stable operation of the machine tool for a long time without failure when it performs its functions under specified conditions. That is, the mean time between failures is long. Even if there is a failure, it can be restored in a short time and put back into use. Choose machine tools with reasonable structure, excellent manufacturing, and mass production. Generally, the more users, the higher the reliability of the CNC system.
