With the improvement of people's living standards, people are more and more interested in metal things, which makes the finished aluminum alloy products more widely used in many industries. Aluminum is widely used in machinery manufacturing, automobiles, electronics, medical and other aviation industries. For example, aluminum is often used in aircraft fuselage skins and compressors to reduce weight. Aluminum replaces steel welding, and the structural weight can be reduced by more than 50%. The domestic aluminum industry is generally nothing more than ordinary machine tools, engraving machines and CNC machining centers.

With the widespread use of aluminum, CNC-processed aluminum parts are becoming more and more popular. However, aluminum alloy is easy to react with oxygen, so surface treatment is often done, and anodized aluminum alloy parts are the most common surface treatment. We have many years of experience in the cnc processing industry and have encountered many customers asking the same question. Does the aluminum alloy anodizing process have a certain impact on precision machinery spare parts? Whenever a customer mentions this issue, we will inform the customer in detail. Aluminum oxide does have an impact on precision mechanical parts, because anodizing is a chemical treatment that modifies the appearance of aluminum alloys, thereby improving the appearance and hardness of mechanical parts. This is the chemical coating technology.

How to control the precision of parts during anodizing process?

The thickness dimensions of some mechanical precision parts are subject to the process requirements. According to the precise dimensions of the oxidation treatment, the machining process dimensions or negative difference dimensions of the parts are increased to ensure that the workpieces after oxidation treatment meet the requirements of deep drawing processing. The processing of mechanical parts is not only the paper size and thickness accuracy, but also the size requirements of fine holes, steps, and hole edges. These requirements are the same as thickness processing.

Aluminum alloy anodizing affects precision mechanical parts, but the cnc machining process of mechanical parts can be controlled to ensure the process and meet the requirements of customer drawings.
