Custom CNC Turning Parts for Zinc Alloys

CNC Turning Surface Finishing Process

Electroplating Processes

Zinc plating significantly enhances part corrosion resistance, making it particularly suitable for agricultural machinery components and architectural hardware used outdoors. The treated surface exhibits a bright finish, and passivation treatment can further strengthen protective properties. Chromium Plating Primarily applied to mold components and hydraulic piston rods requiring high wear resistance, this process achieves a hardness of HV800-1000. It extends part lifespan by 2-3 times, which is crucial for components produced by Precision CNC Turning Services demanding high durability.

Oxidation Treatment

Anodizing is the preferred process for aluminum alloy parts, forming a 5-25μm thick oxide film that combines corrosion resistance with multi-color dyeing capability. Blackening is primarily used for steel components, creating a dense black oxide layer that prevents rust while enhancing aesthetics. It is a common post-treatment option in many metal Turning Services.

Polishing Processes

Mechanical polishing achieves surface roughness as low as Ra 0.025μm, commonly applied to precision components like bearings and seals. Electrolytic polishing excels for complex-shaped stainless steel parts, effectively removing microscopic surface protrusions to significantly enhance corrosion resistance. Professional CNC Turning Service providers typically recommend and implement the most suitable polishing process based on the part's final application, ensuring optimal surface quality.
