Zhongde CNC Machining Process

Zhongde offers a wide range of custom CNC machining services including CNC milling and CNC turning. CNC machining is a subtractive manufacturing process to make custom-machined parts. The CNC machine removes parts of the workpiece by machining operations such as turning, drilling, or milling, according to codes (g-code and m-code) obtained from the CAD model and containing instructions on machining parameters.

CNC Milling Service

CNC milling is a machining method in which a milling cutter is used as a tool for the surface of an object. Use a rotating multi-edge tool to cut the workpiece. CNC milling is also known as a perfect way of making tooling for injection molding.

CNC Turning Service

CNC turn is a method of machining parts for cutting the workpiece on the lathe by rotating the workpiece relative to the tool. CNC turning is suitable for machining revolving surfaces. CNC turning is usually used to create round or tubular shapes.

Material Compatibility



as machined surface finishing

As Machined

For as machined all sharp edges are removed and parts are deburred. Tool marks are visible.

All plastics and metals

Uniform matte of raw material color

smoothing surface finishing


A finishing CNC machining operation can be applied to the part to reduce its surface roughness. Machine marks are less evident but still visible.

All plastics and metals

Uniform matte of raw material color

bead blasting surface finishing

Bead Blasting

Bead blasting adds a uniform matte or satin surface finish on a machined part, removing the tool marks. This is used mainly for visual purposes and comes in several different grits which indicate the size of the bombarding pellets.

All metals

Uniform matte of raw material color

powder coating surface finishing

Powder Coating

Powder coating is a strong, wear-resistant finish that is compatible with all metal materials and can be combined with a bead blasting to create parts with smooth and uniform surfaces and excellent corrosion resistance.

All metals

Black or any RAL code or Pantone number

anodizing color type 2

Anodizing Color(Type II)

Type II anodizing is mainly used to produce parts with a uniform, aesthetically pleasing surface and provides good corrosion and limited wear resistance.

Aluminum alloys

Black, clear or any RAL code or Pantone number

anodizing color type 3

Anodizing Hardcoat(Type III)

Type III anodizing provides excellent corrosion and wear resistance, suitable for functional applications.

Aluminum alloys

Black or clear

electropolishing surface finishing


Electropolishing is an electrochemical process used to polish, passivate and deburr metal parts. It is useful to reduce surface roughness.

All metals

Natural metal color

black oxid surface finishing

Black Oxide

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

Stainless steel and copper alloys


chromate conversion coating surface finishing

Chromate Conversion Coating (Alodine/Chemfilm)

Chromate conversion coating is used to increase the corrosion resistance of metal alloys while maintaining their conductive properties.

Aluminum and copper alloys

Clear or yellow

brushing surface finishing


Brushing is produced by polishing the metal with grit resulting in a unidirectional satin finish. Not advisable for applications where corrosion resistance is required.

All metals
