Common sense of CNC lathe processing

Repetitive production of 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 sum 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 turning 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.



It is required to focus on ensuring the quality of the key parts in small and medium batches that can be produced efficiently: CNC grinding machines can achieve high-precision, high-quality, and high-efficiency grinding machining 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 machining parts is good, the interchangeability is good, and the machining efficiency is high.

The parts processed by the CNC lathe should meet the technological characteristics of the multi-process centralized processing of the CNC grinder or 3d printing. 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 perform some processing accuracy requirements For example, in terms of 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 processing small and medium batches of parts on non-CNC grinders, due to various reasons, the pure cutting time only accounts for 10%-30% of the actual working hours. When china cnc turning on a multi-process centralized CNC grinding machine such as a grinding machining center, this ratio may rise to 70% to 80%, but the preparation time for adjustment is often much longer, so the part batch will become too small. Uneconomical.

Considerations for the processing of some special cnc machining 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.
