Magnesium AZ31BA is a magnesium alloy that offers high strength-to-weight ratio, great corrosion resistance, and excellent machinability. It is ideal for structural and critical components subject to high loads and temperatures.

Analysis of the reasons for the failure of precision parts machining

When precision parts are processed, the product may be affected by quality due to various reasons, ultimately leading to product processing failure. There are several reasons that can cause this consequence, so now let's talk about the analysis of the reasons for the failure of precision parts machining.

The reasons for product failure in precision parts processing can be summarized into four aspects: materials, installation and use, processing and design.

Improper material selection is the main cause of material failure. The most common practice is for designers to make decisions based solely on the conventional performance indicators of the material, and defects in the material itself are also a contributing factor.

When installing and using parts that have already expired, loose or tight fit, improper fixation, poor alignment, and improper operation may all cause usage failure.

3. Poor control of processing technology can cause various defects and failures in precision parts machining. Improper control of heat treatment process can lead to overheating, insufficient tempering, decarburization, etc. Phenomena such as overheating or overburning. Cold processing and poor craftsmanship can result in low smoothness, deep cutting marks, and grinding cracks, all of which can lead to the failure of parts.

4. The first reason for the design is due to the unreasonable structure and shape of the design, which leads to the failure of the parts, such as the presence of obvious stress concentration sources in the high stress areas of the parts. The second is the estimation error of the working conditions of the parts, such as insufficient estimation of possible overload during work, resulting in insufficient load-bearing capacity of the designed parts.
