Aluminum alloy precision parts are widely used in aerospace, semiconductor and automation equipment. Anodizing is one of the most common surface treatments. Poor control in CNC machining stage will amplify defects such as color difference after anodizing, affecting appearance and protection performance.
Processing Difficulties: Aluminum alloy is prone to tool sticking. Tool marks and burrs on the surface will become obvious defects after anodizing.
In the pre-processing stage before anodizing, we optimize CNC finishing process to control surface tool marks, remove edge burrs and keep workpiece clean, reducing residual oil and debris. This ensures uniform appearance and stable protection performance after anodizing.
Pre-inspection is carried out after machining to reduce defects in surface treatment.
We support precision machining of aluminum alloy parts and one-stop service with anodizing and other surface treatments.
