Types and analysis of precision parts processing

Precision parts processing in CNC processing manufacturers refers to the commonly used parts such as threaded parts, keys, pins, Rolling bearings, etc.

Analysis of precision parts machining:

The above parts are referred to as CNC precision machining, which includes standardized fasteners, connectors , Transmission parts, seals, hydraulic components, pneumatic components, bearings, springs and other mechanical parts.

The narrow sense only includes standardized fasteners. The standard parts commonly known in China are the abbreviations of standard fasteners, which are narrow concepts, but the existence of broad concepts cannot be ruled out.

In addition, there are industry standard parts, such as automobile standard parts, mold standard parts, etc., which also belong to precision parts processing.

Precision parts processing mainly refers to other accessories that are freely controlled by the enterprise except that the country has not set strict standard specifications and no relevant parameter regulations. There are many varieties of precision parts processing, and there is currently no very standardized type. The general types are as follows:

1. Metal precision parts processing

The customer provides the drawings, and the manufacturer uses the equipment to make the corresponding products according to the drawings, usually most of the molds, tolerance requirements, smoothness are all It is specified by the customer, and there is no certain paradigm. Products from casting to finishing completely need corresponding quality control, the process is complex and variable, and the general cost is higher than standard parts;

2. Non-metal precision Parts processing

It is the processing of some non-metallic materials. Such as plastic, wood, stone, etc. In recent years, the injection molding industry, the development of plastic molds has become increasingly sophisticated, surface design, and the introduction of programming numerical control have greatly improved the cost and tolerance level of non-standard processing.

For precision parts processing, look for technology to know more and be more professional. If you don't understand, you can consult online or call to discuss.
