Common sense of CNC lathe processing

u200b　 Repetitive production parts of CNC lathe processing: the preparation of the process using CNC grinder occupies a relatively high proportion, such as process analysis preparation, programming, part adjustment and trial cutting, etc. The sum of these comprehensive man-hours is often the part list Tens to hundreds of times the processing time of parts, but the work content of these CNC lathes can be saved and used repeatedly. Therefore, when a part is successfully trial-produced on the CNC grinder and then repeatedly put into production, the production cycle is greatly reduced, the cost is less, and it can be obtained. Better economic efficiency.u200b　　 It is required to focus on ensuring the quality of the key parts in small and medium batches that can be produced efficiently: CNC grinders can achieve high-precision, high-quality, and high-efficiency grinding processing under computer control. Compared with the special grinding machine, it can save a lot of special process equipment, has a strong flexible manufacturing capacity and obtains better economic benefits. Compared with ordinary grinders, it can eliminate many man-made interference factors in the long process flow of complex machining, and the accuracy of the machining parts is good, the interchangeability is good, and the machining efficiency is high. The parts processed by CNC lathes should meet the technological characteristics that can give full play to the multi-process centralized processing of the CNC grinder. When the CNC grinder processes the parts, the grinding wheel cutting workpiece is exactly the same as the corresponding non-CNC grinder, but it can perform some machining accuracy requirements. For example, in the grinding range, ordinary grinders are mainly used to grind cylindrical surfaces, circular CNC lathe cones or the end faces of stepped shoulders. In addition, CNC cylindrical grinders can also grind circles. Torus, as well as the above complex combined surfaces in various forms.　　The processing batch of parts should be larger than that of ordinary lathes and batches of CNC lathes. When non-CNC grinders are used to process medium and small batches of parts, due to various reasons, the pure cutting time only accounts for 10%-30% of the actual working hours. When machining on a multi-process centralized CNC grinding machine such as a grinding machining center, this ratio may rise to 70% to 80%, but the man-hours for preparing adjustments are often much longer, so the parts batch will become too small. Uneconomical. Considerations for the processing of some special parts processed by CNC lathes. Although some parts are processed in small batches, ordinary lathes have complex shapes, high quality and good interchangeability. This cannot meet the above requirements on non-CNC grinders and can only be arranged. Processing on CNC grinders, such as parabola, cycloid cams and special-shaped mirrors, etc.u200b
