Anodizing is an electrochemical process. It is a surface treatment process that uses electrochemistry to form a layer of aluminum oxide protective film on the surface of aluminum and aluminum alloys, thereby improving the corrosion resistance of parts, enhancing wear resistance and hardness, and protecting the metal surface. As well as achieving a more attractive finish.

CNC Machining Overview
What's CNC Machining?
CNC (Computer Numerical Control) machining is a mechanical processing technology that uses computer control. It uses CNC machine tools driven by programming instructions to use various tools to remove materials from workpieces with high precision, thereby realizing a fully automated manufacturing process of workpieces from parts to forming. CNC machining can perform a variety of complex operations such as milling, drilling and turning under automatic programming control.
What's the CNC Machining Process?
Programming: Compile the process route, process parameters, tool motion trajectory, displacement, cutting parameters and auxiliary functions of the parts to be processed into a processing program sheet according to the instruction code and program format specified by the CNC machine tool.
Tools and material preparation: Choose the tool suitable for processing, and ensure that the material is prepared and meets the processing requirements.
Processing process: Input the written program into the CNC device, and send out control signals to control the machine tool to perform actions. In this process, the processing tool performs cutting, drilling and other operations according to a predetermined program, and gradually processes the material into the required parts.
Post-processing: After the processing is completed, the parts are inspected and necessary post-processing, such as deburring, polishing, electroplating, etc., to ensure that the quality requirements are met.
What are the Advantages of CNC Machining?
The high precision, high reliability and diverse selection of materials provided by CNC machining make it the preferred process for complex parts in many industries.. It has many advantages:
