Parts to follow the principle of processing
1. Benchmark first
First processing datum, parts in the process of mechanical processing, as the appearance of the positioning reference should be processed first out, in order to provide a fine datum for the processing of the later process as soon as possible.
2. Divide into the processing stages
Mechanical processing quality should have a high appearance, processing surface can be generally divided into rough processing, semi-finishing and finishing three stages. Mainly in order to ensure the quality of processing, is conducive to the scientific application of equipment, to facilitate the arrangement of heat treatment process, and to facilitate the discovery of blank defects.

3. Face first and then hole
For the box, bracket and connecting rod and other parts should be processed before the hole. In this way, the hole can be processed by plane positioning to ensure the position accuracy of the plane and the hole, and bring advantages to the processing of the hole on the plane.
4. Light processing
The main appearance of the optical finishing processing, such as grinding, honing, fine grinding, rolling processing, etc., should be placed in the final stage of the process route. The principle of drafting the parts processing process route and the formulation of the parts processing process regulations can be roughly divided into two links. The first is to formulate the process route of parts processing, and then determine the size of each process, the equipment and process equipment and cutting specifications, working hour quota, etc.
In machining, the error is inevitable, but the error should be within the allowable range. CNC machinery processing plant believes that through error analysis, master the basic law of its change, so as to take corresponding measures to reduce processing error, improve processing accuracy.
