Do you know the process route of precision metal processing?

Do you want to know what the process route of precision metal processing is? The following is a brief description of the precision metal processing manufacturer as follows:



　　1. Machining the reference surface first: During the processing of the part, the surface as the positioning reference should be processed first, so as to provide a precise reference for the subsequent processing as soon as possible. Called 'benchmark first.'

　　2. Divide the processing stages: the surfaces with high processing quality requirements are divided into processing stages, which can generally be divided into three stages: rough machining, semi-finishing and finishing. The main purpose is to ensure the quality of precision hardware processing; facilitate the rational use of equipment; facilitate the cutting machine to arrange the heat treatment process; and facilitate the discovery of blank defects from time to time.

　　3. Face first, hole second: For parts such as brackets and connecting rods, the plane should be processed first and then the holes should be processed. In this way, the holes can be positioned on the plane to ensure the accuracy of the plane and the position of the hole, and it is convenient for the processing of the holes on the plane.

　　4. Finishing processing: The finishing processing of the main surface (such as grinding, fine grinding, etc.) should be carried out at the last stage of the process route. The surface finish after precision metal processing is above Ra0.8um, with slight collision It will damage the surface. After the cutting machine is smoothed, it must be protected. Hands or other objects are not allowed to directly touch the workpiece to prevent the smoothed surface from being damaged due to the transfer and installation between processes.
