Common knowledge of precision CNC machining

Repeated production of CNC lathes: The use of CNC grinding machines has a high proportion of process preparation time. For example, process analysis preparation, programming, part first part adjustment and trial cutting, etc., the sum of these comprehensive working hours is often several times to hundreds of times of the single piece machining time, but the working contents of these CNC lathes can be saved and reused, so

When a part is successfully tested and put into production on a CNC grinding machine, the production cycle is greatly reduced, the cost is small, and better economic benefits can be achieved.
The key parts of medium and small batches that require processing to ensure the quality of processing and efficient production: 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, has strong flexibility manufacturing capability and obtains good economic benefits. Compared with the ordinary grinding machine, it can eliminate many artificial interference factors in the long process of complex processing, and the precision and interchangeability of the processed parts are good, and the

processing efficiency is high.

The parts processed by CNC lathe should conform to the process characteristics of the multi-process centralized machining of CNC grinding machine. When machining parts with CNC grinding machine, the grinding wheel is the same as the corresponding non-CNC grinding machine, but it can carry out some machining precision requirements. For the composite machining, for example, in the grinding range, the ordinary grinding machine is mainly used for grinding the cylindrical surface, the circular CNC lathe cone surface or the stepped shoulder end of the ordinary lathe grinding, in addition to the CNC cylindrical grinding machine, it can also grind the circle Torus, as well as complex combined surfaces of various forms above.

The processing batch size of parts should be greater than that of ordinary CNC lathes in the processing of non-CNC grinding machines and small batch parts. For various reasons, the pure cutting time only accounts for 10%-30% of the actual working hours. When machining in a multi-process CNC grinding machine with a grinding center, this ratio may rise to 70% to 80%, but the adjustment workmanship is often much longer, so the parts will become too small when they are too small. uneconomic.

Some special parts processing of CNC lathe processing has some parts. Although the processing batch is very small, the ordinary lathe has a complicated shape and high quality, and requires good interchangeability. This cannot be achieved on non-CNC grinders, and can only be arranged. CNC grinding machines, such as parabolic lines, cycloidal cams, and special mirror mirrors.
