Which general principles of precision machining should be followed?

    Nowadays, there are many more kinds of processing on the market, but not all processing is suitable, especially using different machines for processing, so we have to choose according to our actual situation. Shenzhen Machinery Processing is also The same, so which aspects of the general principles of precision machining should be followed?

    1. Process the datum surface first

    During the processing of parts, the appearance 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."

    Second, divide the processing stage

    Appearances with high processing quality requirements are divided into processing stages, which can generally be divided into three stages: rough processing, semi-finishing and finishing. Mainly to ensure the processing quality; facilitate the rational use of equipment; facilitate the arrangement of heat treatment procedures; and facilitate the discovery of blank defects.

    Three, face before hole

   For parts such as box body, bracket and connecting rod, the plane should be processed first and then the hole 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 the processing of the holes on the plane is convenient.

    Fourth, finishing

   The main surface finishing of the workpiece after finishing (such as grinding, honing, fine grinding/rolling processing, etc.) should be stopped at the last stage of the process road. The surface brightness after processing is above Ra0.8um, and the Collision will damage the appearance. In Japan, Germany and other countries, after the finishing process, you must use flannel to stop maintenance. Never touch the workpiece directly with your hands or other objects to avoid the appearance of the finishing process due to the transfer and The device was damaged.
