What are the general principles of CNC machining precision parts?

1. Benchmark first.

That is, the first processing datum, parts in the process of mechanical processing, as the positioning of the surface of the benchmark should be the primary processing out, in order to provide precision for the processing of the subsequent process as soon as possible.

2. Distinguish the processing stages.

Machining quality requirements of the surface, are distinguished by the processing stage, generally can be divided into rough processing, semi-finishing and finishing three stages.The first is to ensure the quality of processing;Conducive to the scientific use of equipment;Easy to arrange heat treatment process;And convenient to find when the blank shortcomings.

3. Face before hole.

On the box, bracket and connecting rod and other parts should be machined after the plane machining hole.In this way, the machining hole can be positioned in a plane to ensure the accuracy of the position of the plane and the hole, and bring convenience to the machining of the hole on the plane.

4. Smooth finishing.

Finishing of primary surfaces, such as grinding, honing, finishing, rolling, etc., should be at the end of the process path.To draw up the general criteria of fine parts processing process road, fine parts processing process procedures can be roughly divided into two parts.

The first is to formulate the process of precision CNC product parts processing road, and then determine each process of the process scale, equipment used and process equipment, as well as cutting specifications, time quota.
