How to protect the selection principles of CNC lathes

1. Preliminary preparation 　　 determine the process requirements of typical parts and the batch of processed workpieces. The function that the CNC lathe should have is to make preparations, and the prerequisites for the reasonable selection of CNC lathes 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. Choose based on reliability. Reliability is a guarantee for improving product quality and production efficiency. The reliability of a CNC machine tool means that the machine tool runs stably 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 into use again. Choose machine tools with reasonable structure, well-manufactured, and mass-produced machines. Generally, the more users, the higher the reliability of the CNC system.　　2. Purchase of machine tool accessories and tools 　　 Machine tool accessories, spare parts and their supply capacity, tools are very important for CNC lathes and turning centers that have been put into production. When choosing a machine tool, carefully consider the compatibility of tools and accessories.　　3. Pay attention to the sameness of the control system. 　　 Manufacturers generally choose the same manufacturer's products, and at least should buy the same manufacturer's control system, which brings great convenience to the maintenance work. Teaching units require students to be knowledgeable and knowledgeable, so it is a wise choice to choose different systems and to equip them with various simulation software.　　4. According to the price ratio, choose 　　 to achieve functions, accuracy, no idleness, no waste, and do not choose functions that have nothing to do with your needs.　　5. Machine tool protection 　　 When necessary, the machine tool can be equipped with fully enclosed or semi-enclosed protection devices and automatic chip removal devices.
