Three principles for precision parts processing that you don't know

If precision parts processing depends on purely basic level to process products, then the hardware parts produced and processed cannot meet the precise statement. To improve the level and accuracy of precision parts processing, you must choose the three basic principles of essential surfaces, as follows:

Principle 1: Principle of overlapping benchmarks. The design benchmark should be selected as the positioning benchmark. Especially in the final completion to ensure accuracy, this principle should be paid more attention to. This can avoid causing position error reference deviation;

Principle 2: Principle of unified benchmarks. Various surface treatments for a unified positioning reference surface should be selected to ensure the position accuracy between each surface as much as possible; sometimes the principle of common reference should be followed and repeated processing should be repeated;

Principle 3: The principle of self-being. Some small machining allowance and a unified finishing process ensure processing quality and productivity, with precision machining surfaces themselves as a basic level.

A clear understanding of the above three principles of precision parts processing will be of great help to improve the process of CNC processing.
