What Is Surface Finishing?

Surface finishing is a post-machining process used to improve the appearance, corrosion resistance, wear resistance, and functional performance of CNC machined parts.

We provide common surface finishing options for aluminum, stainless steel, steel, brass, copper, and plastic parts, helping customers achieve both visual quality and practical performance.

✓ Improve appearance and surface texture
✓ Enhance corrosion and wear resistance
✓ Available for metal and plastic machined parts

Frequently Asked Questions About Surface Finishing

Answers to common questions about surface finishing options, materials, colors, tolerances, and lead times.

We provide anodizing, hard anodizing, bead blasting, polishing, plating, powder coating, black oxide, passivation, brushing, and other common surface finishes for CNC machined parts.

We support surface finishing for aluminum, stainless steel, carbon steel, brass, copper, and some engineering plastics. The suitable finishing method depends on the material, part geometry, and application requirements.

Yes. We can support common anodized colors, matte or glossy finishes, brushed textures, polished surfaces, and coating requirements. For strict color matching, a physical sample or color reference is recommended.

Some finishes may slightly change surface thickness or dimensions, especially anodizing, hard anodizing, plating, and powder coating. We recommend confirming critical tolerances and masking requirements before production.

Please provide 2D drawings, 3D files, material grade, quantity, required finish, color, tolerance requirements, and any special inspection standards.

Lead time depends on the finishing method, quantity, color, and inspection requirements. Standard finishes usually take a few additional working days after machining.
