Surface Finishes For CNC Machined Parts

As machined (Ra 3.2μm / Ra 126μin)

This finishing option with the shortest turnaround time. Parts have visible tool marks and potentially sharp edges and burrs, which can be removed upon request.

Smooth machining (Ra 1.6μm / Ra 63μin)

Smooth machining is similar to a ‘As machined’ finish, but with less visible machine marks. Parts are machined at a lower feed rate, with no hand polishing.

Polishing (Ra 0.8μm / Ra 32μin or better)

Polishing is the process of creating a smooth and shiny surface by rubbing it or by applying a chemical treatment.
bead blasting

Bead Blasting

Machined parts are bead blasted with glass beads which results in a uniform grainy texture and reduced machining marks.
1.4404 stainless steel parts


It is a process that tumbles vibrating media on machined parts to remove sharp edges and burrs. Tumbling can be used to remove machine marks from exterior surfaces.
6061-T6 red anodizing parts

Bead blasted + Anodizing
type II

The parts are bead blasted to #120 grit before being anodized type II—ideal for increasing the aluminum part’s corrosion resistance and cosmetic effects.

Bead blasted + Anodized type III (Hardcoat)

The parts are bead blasted to #120 grit before being anodized type III. Type III (Hard Coat) is thicker and adds a wear-resistant layer to Type II’s corrosion resistance, suitable for functional applications.

Black Oxide

Black oxide is a conversion coating that is used on steels to improve corrosion resistance and minimize light reflection.

Powder Coated

This is a finish of applying powdered paint to the components and then baking it in an oven, which results in a stronger, more wear- and corrosion-resistant layer that is more durable than traditional painting methods.

Chromate Conversion Coating

Chromate conversion coating is used to improve the corrosion resistance of aluminum and aluminum alloys while keeping their conductive properties. It is also applied as a base layer prior to priming and painting parts.


Include Nickel Plating, Silver Plating, Gold Plating, Zinc Plating, Chrome Plating, Tin Plating and etc, it is ideal to reduce corrosion, improve the appearance and function of solderability and electrical conductivity.

DLC (Diamond-Like Carbon) Coating

DLC (Diamond-Like Carbon) coating is a hard, wear-resistant coating made of a carbon-rich material that exhibits some of the properties of diamonds.

What Is CNC Machining?

Besides our primary CNC machining services, we enhance production with a variety of manual equipment. This includes resources for manufacturing tooling, jigs, and fixtures, as well as for executing processes like sheet metal fabrication and bending. Our capabilities also extend to cutting and sawing tasks.

Low-volume CNC machining services are a useful bridge between rapid prototyping and mass production, ideal for trial orders and market testing. It serves as a practical assessment strategy for upcoming mass production schedules. For this reason, an increasing number of companies choose vacuum casting or CNC machining, expediting product market entry while providing scope for product improvement based on user feedback.
