What is CNC Turning?
In CNC turning, material is held in a chuck and rotated by using tooling attached to a turret. Furthermore, the tool moves to the raw bar of material to remove material. The process is also known as “subtraction machining” since the material is removed. A center that has tuning and milling capabilities, such as the one pictured above, can be slowed so that other shapes can be milled out.
How CNC Turning Work?
From prototyping to full-scale production. High-quality parts can be produced with our CNC lathes and turning centers to meet even the strictest requirements.
Standard Materials for CNC Milling
Hundred of commercial-grade metal and plastic materials are suitable for both prototyping and production.

| Powder Coating | All metals | 10-80μm | RAL code, Pantone number |
| Zinc-Nickel | All metals | 5-25 μm | Clear, Black , Iridescent |
| Chromate coating | Steel and Aluminum | 0.25-1.0μm | Yellow or clear Iridescent |
Anodizing
Anodizing treatment provides an aluminum oxide layer for metal parts, which protects against corrosion & adding an optional color surface.
Specifications:
RoHS compliant
Type two ( color)
Class 1 (clear)
Class 2 (black)
Black oxide
Black oxide produces a magnetite layer on the surface for ferrous, non-ferrous, and powdered metals to Add Mild corrosion resistance and minimize light reflection.
Specifications:
RoHS compliant
Hot black oxide
Mid-temperature black oxide
Cold black oxide
Chromate coating
Chromate coating is a type of conversion coating, which by producing a thin coating on the nonferrous surface, such as zinc, aluminum, and tin plate to improve paint adherence.
Specifications:
Type two, RoHS compliant
Class1A: For max protection against corrosion, painted or unpainted
Class 3: For max protection against corrosion where low electrical resistance is required
Tempering
Tempering is a process of not only increasing metal hardness levels to obtain tougher and more durable properties but also dissolving solute-rich precipitates.
Specifications:
Quenched and tempered
Conditioning
HRC 10 to HRC 65
Part marking
Part marking is a process of marking parts with product info, such as serial numbers, part numbers, and logos, which allow the tracking of parts across the full product life circle.
Specifications:
Laser engraving
Silk printing
CNC Marking
