General Knowledge of CNC Machining

CNC Truning repetitive parts put into production: the use of CNC grinder process preparation time comrade-in-arms higher proportion. For example, preparation of process analysis, programming, adjustment and trial-cutting of Parts’first parts, etc., the sum of these comprehensive working hours is often tens to hundreds of times of the working hours of Parts’ single-part processing, but the working contents of these CNC lathes can be saved and reused, so when a part is successfully manufactured on a CNC grinder and put into production again and again. The production cycle is greatly reduced, the cost is reduced, and good economic benefits can be obtained.

It is required that the key parts of medium and small batches produced with high quality and high efficiency should be processed: CNC grinding machine can realize high precision, high quality and high efficiency grinding under the control of computer. Compared with the special grinding machine, it can save a lot of special process equipment, has a strong flexible manufacturing ability and obtains better economic benefits. Compared with ordinary grinding machine, it can eliminate many human interference factors in the long process of complex processing, and has good accuracy consistency and interchangeability of parts, and high processing efficiency.

The parts processed by CNC Machine should conform to the technological characteristics that can give full play to the multi-process centralized processing of CNC grinder. When CNC grinder processes parts, the situation of grinding wheel cutting workpiece is exactly the same as that of corresponding non-CNC grinder, but it can carry out some compound processing with the requirement of processing accuracy, such as in the grinding range. Ordinary grinding machine is mainly used to grind cylindrical surface, conical surface of circular NC lathe or end face of stepped shoulder. In addition to NC cylindrical grinding machine, it can also grind ring surface, as well as all kinds of complex combination surface.

The processing batch of parts should be larger than that of ordinary lathe batch CNC lathe in non-CNC grinder processing, small batch parts. For various reasons, the pure cutting time only accounts for 10%-30% of the actual working hours. When processing on CNC grinder with multi-process centralization such as grinding processing center, this proportion may rise to 70%-80%. But preparing to adjust the working hours is often much longer, so it will become uneconomical when the batch size of parts is too small.

Considering the processing of some special parts processed by CNC NC lathe, although some parts are processed in small batches, ordinary lathes have complex shapes, high quality and good interchangeability, which can not meet the above requirements on non-CNC grinders, and can only be processed on CNC grinders, such as parabola, cycloidal cams and special ones. The mirror of the surface, etc.
