Repetitive production parts processed by CNC lathes: The process preparation man-hours using CNC grinders occupies a relatively high proportion. For example, process analysis preparation, programming, adjustment and trial cutting of the first part of a part, the total of these comprehensive man-hours is often dozens to hundreds of times the man-hours of a single part processing
but the work content of these CNC lathes can be stored and used repeatedly, so When a part is successfully trial-produced on a CNC grinder and then repeatedly put into production, the production cycle is greatly reduced, the cost is less, and better economic benefits can be obtained. It is required to focus on ensuring the quality of the key parts in small and medium batches that can be efficiently produced: 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 processing, and the accuracy of the processed parts is good, the interchangeability is good, and the processing 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 cuts the workpiece and the corresponding non-nc grinder is exactly the same, but it can carry out some processing 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. When processing small and medium-sized parts on non-CNC grinders, the pure cutting time only accounts for 10%-30% of the actual working hours due to various reasons. 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 if the batch of parts is too small, it will become 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.
