CNC numerical control lathe machining small common sense Россия

Repetitive parts processed by CNC lathes: A high proportion of process preparation man-hours using CNC grinding machines are used. For example, process analysis preparation, preparation of procedures, part first piece adjustment and trial cutting, etc., the sum of these comprehensive man-hours is often dozens of times to hundreds of times the man-hours of single piece processing of parts, but the work content of these CNC lathes can be saved and used repeatedly, so when a part is successfully trial-produced on the CNC grinding machine and then repeatedly put into production, the production cycle is greatly reduced, the cost is also less, and better economic benefits can be obtained.

It is required to focus on ensuring the processing quality and can produce small and medium-sized batches of key parts efficiently: CNC grinding machines can achieve high-precision, high-quality and high-efficiency grinding under computer control. It can save a lot of special process equipment than special grinding machine processing, and has strong flexible manufacturing ability and good economic benefits. Compared with ordinary grinding machines, it can eliminate many artificial interference factors in the long process of complex processing, and the accuracy consistency and interchangeability of the machined parts are good, and the processing efficiency is high.

The parts processed by CNC lathes should conform to the process characteristics of multi-process centralized processing of CNC grinders, and the situation of grinding wheels cutting workpieces when CNC grinders process parts is exactly the same as that of the corresponding non-CNC grinders, but it can carry out some composite processing with machining accuracy requirements, such as in terms of grinding range, ordinary grinders are mainly used for grinding cylindrical surfaces, Circular CNC lathe cone or stepped shaft shoulder of the end face of ordinary lathe grinding, CNC cylindrical grinder in addition, can also grind toroids, as well as the above various forms of complex combined surfaces.

The processing batch of parts should be greater than that of ordinary lathes when CNC lathes process medium and small batches of parts on non-CNC grinding machines, due to various reasons, the pure cutting time only accounts for 10%-30% of the actual working hours. In the grinding machining center, such as multi-process concentrated CNC grinding machine, this proportion may rise to 70%~80%, but the preparation of adjustment man-hours is often much longer, so the batch size of parts is too small to become uneconomical.

Consideration of some special parts processing of CNC CNC lathes Although the processing batch is very small, ordinary lathes have complex shapes, high quality, and good interchangeability, which can not meet the above requirements on non-CNC grinding machines, and can only be arranged to be processed on CNC grinding machines, such as parabolas, cycloidal cams and mirrors with special profiles.
