How to prevent damage to precision parts during machining?

With the continuous development of the industry, we understand that various industries are developing rapidly, so in the process of precision parts processing, it may cause certain damage, most of which may be caused by us in the process of use , it may also be caused by the machining process, so how to prevent damage to precision parts during machining? Let's take a look below!

First, good casting structure design

The thickness of the casting wall should be as uniform as possible to avoid hot spots and reduce the heat caused by the local heat concentration of the mold. fatigue. During the casting process, the corners of the casting should be set with appropriate casting fillets to avoid the sharp corners of the mold and the resulting stress.

Second, reasonable design of mold structure

1. Precision parts and components should have sufficient rigidity and strength to withstand pressure without deformed. The wall thickness of the mold must be sufficient to reduce deformation;

2. It is the design of the gating system to minimize the erosion of the core;

3. Correct selection of each Durability and surface roughness of components;

4. Maintain thermal balance of precision parts.

Three, standardize the heat treatment process

After heat treatment, the metallographic structure of the material changes, ensuring the necessary strength, hardness, high temperature dimensional stability, thermal fatigue resistance and cutting performance.

Appropriate heat treatment process can obtain the best performance of precision parts, while the performance of steel is controlled by quenching temperature and time, cooling rate, and tempering temperature. That's all for this article. For more information, please pay attention to this precision parts processing website.
