Repetitive production parts processed by CNC lathes: the use of CNC grinders accounts for a relatively high proportion of process preparation man-hours, such as process analysis preparation, programming, part adjustment and test cutting, etc. The total of these comprehensive man-hours is often a single part The processing time is dozens to hundreds of times, 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 more can be obtained. Good economic benefits.

CNC lathe parts processing

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.
