The repetitive production of parts: the use of CNC grinders occupies a high proportion of process preparation man-hours. For example, process analysis preparation, programming, adjustment and trial cutting of the first part of a part, the sum of these comprehensive man-hours is often dozens to hundreds of times the man-hours of a single part processing, but these CNC lathes can be stored for repeated use 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 produced efficiently: CNC grinders can achieve high-precision, high-quality, and high-efficiency grinding processing under computer control. Compared with special grinding machine processing, 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 artificial 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.

CNC grinders

The parts should be in accordance with the process characteristics of 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-CNC grinder is exactly the same, but it can perform some complex processing with machining accuracy requirements. For example, in terms of the grinding range, ordinary grinders are mainly used for grinding cylindrical surfaces, circular CNC lathe cones or the end faces of stepped shoulders. In addition, CNC cylindrical grinders can also grind toroidal surfaces, and The above complex combined surface 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 process small and medium-sized 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.

Some considerations for the processing of some special parts. 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 processed on CNC grinders. , Such as parabola, colloid cam, and special-shaped mirror.
