Determine the process requirements of typical parts, the batch of processed workpieces, and the function that the proposed CNC lathe should have is to make preliminary preparations, and the prerequisite for reasonable selection of CNC lathes: to meet the process requirements of typical parts.
The process 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. According to the reliability to choose, reliability 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 performing its functions under specified conditions. That is, the average time between failures is long, even if there is a failure, it can be recovered in a short time and put back into use. Choose machines that are well-structured, well-manufactured, and mass-produced. Generally, the more users, the higher the reliability of the CNC system.
