The repetitive production parts processed by CNC lathes: The preparation time for the process using CNC grinding machines accounts for a high proportion. For example, the total working time of process analysis preparation, programming, first piece adjustment of parts, trial cutting, etc. is often tens to hundreds of times that of single piece processing of parts. However, the work content of these CNC lathes can be saved and reused. Therefore, when the CNC grinding machine successfully produces, the production cycle is greatly reduced, the cost is low, and better economic benefits can be achieved.
Small and medium-sized key components: CNC grinding machines can achieve high-precision, high-quality, and efficient grinding processing under computer control. Compared with specialized grinding machines, it can save a large amount of specialized process equipment, has strong manufacturing capacity, and has good economic benefits. Compared with ordinary grinding machines, it can eliminate many human interference factors in complex machining processes, and the accuracy consistency and interchangeability of processed parts are good, with high machining efficiency.
The parts processed by CNC CNC lathes should meet the process characteristics of fully utilizing the multi process centralized processing of CNC grinding machines. When CNC grinding machines process parts, the grinding wheel cuts the workpiece exactly the same as the corresponding non CNC grinding machine, but it can perform some composite processing with machining accuracy requirements. For example, in terms of grinding range, ordinary grinding machines are mainly used for grinding cylindrical surfaces, circular CNC lathe conical surfaces, or stepped shoulder end faces. In addition, CNC cylindrical grinding machines can also grind circular surfaces and complex combination surfaces of the above forms.
The processing batch of parts should be larger than that of ordinary lathes. In non CNC grinding machine processing, due to various reasons, pure cutting time only accounts for 10% -30% of the actual working hours. When processing on CNC grinding machines with multiple concentrated processes such as grinding centers, this proportion may increase to 70% to 80%, but the preparation time for adjustment is often much longer, so a small batch size of parts can become uneconomical.
CNC considers some special parts processed by CNC lathes. Although some parts are processed in small batches, they have complex shapes, high quality, and good interchangeability, which cannot meet the above requirements. They can only be arranged to be processed on CNC grinding machines, such as parabolas, cycloidal cams, and special surface mirrors.
