Whether it’s a quick-turn prototype in one day or 1,000 units at the right price, RapidDirect can help.

CNC milling Services Rapid Direct

CNC Milling

CNC milling cuts shapes out of a metal or plastic material blank that is usually flat, holding dimensions to tolerances as tight as 0.002”.
CNC Turning Services Rapid Direct

CNC Turning

Typically used to create a rounded surface, turning rotates the part when machining the desired shape, whereas milling rotates the tool.

RapidDirect provides surface finishes on all CNC parts, including anodizing, electroplating, bead blasting, polishing, brushing, powder coating, and painting.

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.

surface finish - anodizing

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.

surface finish - bead blasting

Powder coating forms a durable, wear resistant and corrosion resistant layer on the surface of parts. Powder coating can be used to apply colors to parts and is compatible with any metal.

surface finish - powder coating

Electroplating can be functional, decorative or corrosion-related. Many industries use the process, including the automotive sector, in which chrome-plating of steel automobile parts is common.

Electroplating Image

Polishing is the process of creating a smooth and shiny surface, either through physical rubbing of the part or by chemical interference. The process produces a surface with significant specular reflection, but in some materials is able to reduce diffuse reflection.

Polishing Image

Brushing is a surface treatment process in which abrasive belts are used to draw traces on the surface of a material, usually for aesthetic purposes. Most commonly applied to aluminum.

Painting the surface of a part improves its aesthetic appearance and can provide brand recognition to consumers. In addition, painting can have a protective effect on parts.

Our standard tolerances for CNC machining of metals is DIN-2768-1-fine and for plastics is DIN-2768-1-medium. Tolerances are greatly affected by part geometry and type of material. Our project managers will consult with you on every part of your project and will seek to provide the highest degree of precision possible.
