Available Material For CNC Machining

Our CNC machine shop can machine virtually any engineering material, including plastics, metals, alloys, foam or tooling board. Here is a list of our standard CNC machining materials available, other materials are upon request.

Available Surface Finishes After CNC Machining Services

Surface finishes are applied after machining and can change the appearance, surface roughness, hardness and chemical resistance of the produced parts. Below are the mainstream surface finish types from DEK:

As Machined

As Machined

This is the standard choice, economical and rapid, the parts’ surface will leave visible machining marks. The surface finish is equivalent to 3.2RA μm (125 RA μin).

Polishing Surface Finish


Polishing is to make the surface smooth by physical friction processing, it is often used to prevent corrosion and remove oxidation. After polishing, the parts have a smoother and brighter finish.

Beat Blasting Finishing

Bead Blasted

Bead blasting is the process of spraying abrasive on the surface of parts under high pressure, after sandblasting, the metal parts have a satin texture or frosted surface, eliminating the processing marks.

Anodized Parts Anodizing Finish


After anodizing, a hard non-conductive ceramic coating will be added on the surface of aluminum parts to improve the wear resistance and retain the metal texture and luster.



Electropolishing is the reverse process of electroplating, which simplifies the metal surface at the micro-level through chemical solution. After electropolishing, metal parts can be more bright and reduce surface roughness.

Black Oxided Parts

Black Oxide

The black oxide is a chemical conversion coating, it is produced by a chemical reaction between iron and oxide salt in black oxide solution. The corrosion resistance of parts can be improved after black oxidation.

Powder Coated

Powder Coated

Powder coating can add a layer of solid and colorful polymer coating on the surface of parts, so as to improve the wear resistance and corrosion resistance.

Spray Painting

Spray Painting

Spray painting is to spray paint on the surface of parts in the air. After painting, the parts have various colors, improve the aesthetic appearance, and make the parts unique, enhance brand awareness.

Other surface finishes are also available. Please click here to learn all surface finish knowledge. Or contact our sales team to get an instant quote.

Cilents & Feedbacks

DEK is our best China CNC machining supplier, we have cooperated for over 18 years, and their quality is always well.

In January 2020, we developed a new automated mask machine, which composed of over 430 kinds of spare parts. In total, we need 250 pieces of automated mask machine, which means the number of spare parts above 120.000 pcs. This is a hard project because there are many machining technologies involved, including large milling, 5 axis milling, turning, grinding, drilling, EDM, etc, and the lead time is only 40 days.

Finally, DEK produced all the parts on time, an excellent experience!
