Precision CNC Surface Finishing Solutions
One-stop Surface Treatment For Custom Machined Parts | High Precision, Anti-corrosion & Stable Roughness
Sand Blasting Surface Treatment
Adopt fully enclosed dust-free cabinet sand blasting equipment, professionally remove CNC machining tool marks, sharp burrs and surface oxide scale of precision parts. Form uniform and stable matte surface texture, accurately control workpiece surface roughness Ra value, greatly enhance the adhesion effect of subsequent anodizing, plating and powder coating processes, and ensure consistent surface quality of batch parts.
Precision Aluminum Anodizing
Professional customized hard anodizing & decorative anodizing for aluminum alloy CNC parts. Multiple color appearance options available, with excellent wear resistance, corrosion resistance and insulation performance. The oxide film will not damage the original dimensional tolerance of parts, fully comply with ISO international precision surface finishing standards, and greatly extend the service life of mechanical parts.
Ultra-fine Mirror Polishing Finish
Multi-stage fine grinding and mirror polishing process for stainless steel, copper and precision alloy parts. Effectively reduce workpiece surface roughness to ultra-low Ra range, create high-brightness smooth mirror surface effect. Meet high-precision assembly matching requirements, improve product appearance grade and surface smoothness, without changing the original precision size of CNC machined parts.
Stainless Steel Anti-rust Passivation
Standardized environmental-friendly passivation surface treatment for 304/316 stainless steel parts. Form dense anti-corrosion protective film on workpiece surface, fundamentally solve rust and oxidation problems of stainless steel in long-term use. Maintain the original precision size and mechanical properties of parts, fully adapt to harsh working conditions such as outdoor, humid and corrosive environments.
Mitutoyo High-Precision Surface Roughness Inspection
Adopt imported Mitutoyo professional surface roughness tester, to accurately detect and control the surface roughness Ra value of all finished parts. From sand blasting, polishing to anodizing, every surface finishing process is strictly inspected, ensuring consistent surface quality, stable assembly performance and long-term reliability of customized CNC machined parts, fully meeting ISO international precision standards.
