Surface Finishes for CNC Machining

With a wide selection of surface finishes, RapiDirect can help improve the surface qualities of your products. Surface finishes applied to your CNC turned parts aim at improving their appearance, surface hardness and roughness, chemical and corrosion resistance, etc. They also help hide any visible tool marks from areas cut with live tooling. Here are some of your top choices.

Name Description Materials Color Texture Link
Anodizing Anodizing improves corrosion resistance, enhancing wear resistance and hardness, and protecting the metal surface. Widely used in mechanical parts, aircraft, and automobile parts, precision instruments, etc. Aluminum Clear, black, grey, red, blue, gold. Smooth, matte finish. Learn More>>

Bead Blasting

Bead blasting results in parts with a smooth surface with a matte texture. Used mainly for visual applications and can be followed by other surface treatments.

Powder Coating Powder coating is a type of coating that is applied as a free-flowing, dry powder. Unlike conventional liquid paint which is delivered via an evaporating solvent, powder coating is typically applied electrostatically and then cured under heat or with ultraviolet light.

Frequently Asked Questions

The CNC turning process is mostly ideal for cylindrical-shaped raw materials. However, several manufacturers also use it for hexagonal and square-shaped workpieces. It is a popular method for making machine parts for microfluidic tools, signage components, surgical instruments, automotive frames, and aerospace parts.

We can turn parts with diameters ranging from 0.5mm to 65mm for stock bars. Our turning capabilities can reach up to 3000 mm for billets.

Yes, our CNC turning services include plastic parts manufacturing. We can produce small or large batch prototypes and production parts from various engineering-grade plastics. Choose from our extensive range of plastic materials and upload your design file to get custom plastic components.

The major difference between CNC milling and CNC lathe is in their machining process. CNC milling involves rotating the cutting tools against a stationary bar stock or workpiece. In contrast, a CNC lather works by rotating the bar stock or workpiece against a stationary tool. CNC milling is more suitable for machining irregular and flat surfaces, while CNC lathes work best for cylindrical or conical parts.
