Four Principles to Follow in Precision Casting Casting Processing

In order to ensure the quality of precision parts during the precision casting process, four principles need to be followed. Today, precision casting manufacturer Tianyao Metal will introduce in detail what these four principles are.

1、 Datum first: that is, machining the reference surface first. During the machining process of the part, the outer surface that serves as the positioning reference should be machined first to provide a precise reference for subsequent processing as soon as possible.

2、 Dividing processing stages: For surfaces with high quality requirements in mechanical processing, they are divided into three stages: rough machining, semi precision machining, and precision machining. Mainly to ensure processing quality; Beneficial for scientific application equipment; Facilitate the arrangement of heat treatment processes; And facilitate the timely detection of defects in the raw material.

3、 Face before hole: For parts such as the box, bracket, and connecting rod, the plane should be machined first before the hole. In this way, holes can be machined with planar positioning, ensuring the positional accuracy of the plane and holes, and bringing convenience to the machining of holes on the plane.
