CNC Turning Surface Finishes
Achieve the perfect finish for your CNC-turned parts with our range of surface treatment options.
Anodized
Specific to aluminum, this finish can range from smooth to matte or gloss, with customizable colors. A thin layer (0.002mm to 0.04mm) is removed.
Polishing
The polished finish offers a high gloss, smooth surface with Ra 0.8μm (Ra 32μin) roughness, ideal for mirror-like applications.
Bead Blasting
Metals or plastics parts surface is left with a smooth, matte appearance, with no thickness removal specified.
Black Oxide
Black oxide is a corrosion-resistant treatment for metals, providing a matte black finish, mild rust protection, and improved wear resistance.
Powder Coating
Applicable to metals, offering matte, gloss, or textured finishes with customizable colors. Thickness removed ranges from 0.05mm to 0.15mm.
As Machined
This finish retains visible tool marks and is suitable for both metals and plastics. There is no specific thickness removed in this finish.
Brushing
Brushing produces a satin texture on parts, offering a smooth, uniform finish while concealing minor flaws.
Electroless Nickel Plating
Electroless Nickel Plating provides a uniform, corrosion-resistant finish on metals, with excellent hardness and wear resistance.
Chromate Conversion Coating
This finish can appear smooth or matte, often with a clear or slight yellow tint. A very thin layer (0.25–1 micrometer) is removed.
E-Coating
This finish, suitable for metals, can be matte or gloss, with black as the most common color.
Painting
Available for metals and plastics, this finish can be matte, gloss, or textured, with color matching possible.
Heat Treatment
Heat treatment enhances metal properties such as hardness, strength, and toughness through controlled heating and cooling processes.

CNC Turning Overview
What is CNC turning?
CNC turning is an ideal device for cutting symmetrical cylindrical or spherical parts. Typically, a lathe rotates the workpiece on a vertical or horizontal axis, while a fixed forming tool moves around the workpiece on a straight or curved path.
What is the principle of CNC turning?
CNC turning allows for a variety of operations such as face, threading, knurling, drilling, boring, reaming and taper turning. It works by loading the raw material into the lathe spindle tray after creating the G code. When the spindle rotates, the chuck holds the workpiece in place. Once the spindle reaches speed, the cutting tool makes contact with the workpiece, gradually removing the material until the desired geometry is formed.
What is the difference between CNC turning and milling?
The main difference between CNC turning and CNC milling lies in the relative movement of the machine and raw materials during the machining process. In CNC milling, the material is fixed in position and the cutting tool rotates around the material. In CNC turning, the tool remains in the same position while the material rotates at high speed to form a precise shape.
Other differences include:
- Tool types: single point tools are used for turning, and multi-point tools are used for milling.
- Applicability: Milling is more suitable for flat and irregular surfaces, while turning is suitable for cylindrical or conical surfaces.
- Cutting method: turning continuous cutting, with the tool continuously in contact with the workpiece;
- Milling intermittent cutting, where the tool continuously engages and disengages from the material.
- Chip type: Milling produces discontinuous chips, while turning can produce discontinuous, continuous, and fragmented chips.
