Micro machining occurs through automated selective material removal with special ultra-small cutting tools. The CNC precision machining process begins with creating a detailed CAD model that serves as the machining process blueprint. Then, the operator programs the CNC machine with CAD/CAM software that translates the 3D model design of the to-be machined product into precise …
Manufacturers employ different CNC machining surface finishing measuring methods to determine if the achieved degree of surface finish allows the parts to meet the specific surface finish requirements and performance criteria. Each technique provides insights into the surface irregularities, texture, and overall quality. These measuring methods include:
1 AnnealingAnnealing is a CNC metal finishing process that involves heating a material until it recrystallizes, then putting it in sand to cool gradually or cooled to room temperature in the oven. Although the cooling process is slow, it helps reduce the metal’s hardness, increase its elasticity, and enhance its cold working capacity. 2 Heat …
1 PassivationIt is a standard chemical finishing treatment used to improve the corrosion resistance of machined parts. The passivation process involves dipping the material in a chemical bath that removes iron from its surface, providing a smooth, shiny finish. 2 Chemical Conversion CoatingAlso referred to as chromate coating, it is a CNC machining surface finishing …
