Non-standard machining technology (heat treatment process), determine the machine tool, clamping method, measurement method, processing allowance, cutting amount and working hour quota used in each process. Fill each content on the process specification table, which is the specification of mechanical processing technology. There are strict requirements, positive and negative errors within the specified range of requirements are qualified parts, otherwise they are unqualified parts.

Such as an embedded cylinder, if the diameter is too large, beyond the allowable range of error, it will cause, can not be inserted into the situation, if the actual diameter is too small, beyond the allowable negative lower limit of error, it will cause too loose, unstable problems occur. Non-standard precision parts processing equipment and equipment, advanced processing equipment makes the processing of precision parts more simple, higher precision.

One of the main characteristics of the development of auto parts is that system development and module customization are currently being implemented. This can largely meet the needs of the development of the group, is a strategic choice for many auto parts industry. Through system development and modular manufacturing, we can follow the trend of industry development and always walk in the forefront of industrial development.

With the increasing variety of auto parts, there are now more and more automobile brands, and the types of non-standard machining are also more and more. Therefore, when processing auto parts, the transfer speed is relatively fast to meet domestic needs. Because most car parts are made of metal.

If the environment is wet when stored, it is easy to appear traces of rust, therefore, in order to be able to choose better quality auto parts, be sure to look at its surface has no traces of rust, only such products, can be more assured to use.
