The concept of non-standard parts processing
Non-standard parts processing is proposed relative to the processing of standard parts.
Standard parts processing refers to the commonly used zero (parts) parts, such as threaded parts, keys, pins, rolling bearings, etc., which have been fully standardized in terms of structure, size, drawing, marking, etc., and are produced by professional factories. Generalized includes standardized fasteners, joints, transmissions, seals, hydraulic components, pneumatic components, bearings, springs and other mechanical parts. In the narrow sense, only standardized fasteners are included. The standard part in China is the abbreviation of standard fasteners, which is a narrow concept, but cannot exclude the existence of general concepts. In addition, there are industry standard parts, such as automotive standard parts, mold standard parts, etc., which are also generalized standard parts.
The processing of non-standard parts is mainly that the country has not set strict standard specifications, and there are no other parameters that are freely controlled by the enterprise.
