Zhongde CNC Turning Service

CNC turning is a method of cutting the workpiece on the lathe by rotating the workpiece relative to the tool. It is suitable for machining revolving surfaces. Most workpieces with revolving surfaces can be processed by turning, such as inner and outer cylindrical surfaces, inner and outer conical surfaces, end faces, grooves, threads, and revolving forming surfaces.

Zhongde, as a professional CNC machining company in China, supplies customized precision CNC turning service and CNC milling service for all your requirements, such as quick turn production machining, with affordable prices and considerate service.

The wide range of CNC lathes and turning centers, and various materials and surface treatment options will allow us to produce high-precision, high-standard custom CNC machined parts. Whether plastic CNC machining parts or metal CNC machining parts, you will get a competitive price.

CNC Turning Surface Finishing

CNC Turning Parts surface finish is critical to a successful part design and it is used for aesthetic and functional reasons in injection molded parts for engineering products. The surface finish improves the look and the feel of a product as the perceived value and quality of the product increase with a suitable surface finish.

Different grades of surface finishing chart.



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

Natural metal color
