What is CNC Machining?
CNC (Computer Numerical Control) machining is a subtractive manufacturing process in which computer-controlled machines precisely remove material from a solid block to create custom parts. It supports 3-axis, 4-axis, and 5-axis machining, enabling the production of parts with complex geometries, tight tolerances, and excellent repeatability. CNC machining works with a wide variety of metals and engineering plastics, making it ideal for both rapid prototyping and low-volume production. At Imago, we combine advanced equipment with deep process expertise to deliver high-quality, reliable results for demanding applications.

Surface Finishes & Post-Processing
| Image | Surface Finish | Description | Process | Applicable Materials |
|---|---|---|---|---|
 |
As Machined | Standard CNC machined surface finish with a uniform 3.2 μm (126 μin) surface roughness. This baseline post-CNC machining process cleanly eliminates sharp edges and burrs left from milling, turning and other CNC cutting operations, ideal for functional parts without extra decorative coating requirements. | CNC machining, Sheet metal fabrication | Metals, Plastics |
 |
Sand Blasting | Common pre-treatment step for CNC machined metal components. High-pressure equipment propels abrasive blast media onto workpiece surfaces to strip old coatings, surface contaminants, oxidation layers and machining residues, creating a uniform matte base for subsequent anodizing, plating or powder coating on CNC parts. | CNC machining, Sheet metal fabrication | Metals, Plastics |
 |
Anodizing | Specialized electrochemical surface finishing widely applied to CNC machined aluminum parts. The anodizing reaction generates a tough, anti-corrosion oxide film bonded to the metal substrate, significantly boosting the durability, wear resistance and weather resistance of CNC aluminum workpieces while supporting customizable color tinting. | CNC machining, Sheet metal fabrication | Aluminum |
 |
Electroplating | Widely used protective & decorative surface treatment for CNC machined metal components. The electroplating process utilizes electrical current to deposit uniform, tightly bonded metal coatings onto CNC workpiece surfaces by reducing dissolved metal ions, enhancing rust resistance, hardness and visual appeal of CNC machined steel, copper and alloy parts. | CNC machining, Sheet metal fabrication | Metals |
 |
Painting | Liquid paint coating service for finished CNC machined components. Custom paint layers are applied to CNC metal and plastic workpieces to deliver vivid aesthetic upgrades, alongside a protective barrier against scratches, oxidation and environmental corrosion for general CNC machining projects. | CNC machining, Sheet metal fabrication, Injection molding, 3D printing | Metals, Plastics, Wood |
 |
Powder Coating | Eco-friendly dry surface finishing solution for CNC machined metal parts. This solvent-free powdered paint process delivers thick, uniform, long-wearing protective coatings with superior chip, scratch and corrosion resistance, a top durable finish choice for industrial CNC machined workpieces. | CNC machining, Sheet metal fabrication, Injection molding | Metals, Some Plastics |
 |
Brushed Finish | Mechanical abrasive polishing finish for CNC machined stainless steel, aluminum and alloy parts. Controlled linear brushing creates a consistent unidirectional satin texture on CNC workpieces, balancing subtle decorative texture and moderate scratch resistance for consumer hardware CNC components. | CNC machining, Sheet metal fabrication | Metals |
 |
Polishing | Precision surface smoothing process for CNC machined metal parts. Polishing eliminates fine machining scratches, surface blemishes and tool marks to achieve a mirror-bright reflective finish, serving both aesthetic upgrades for visible CNC parts and functional performance improvements for precision CNC machined components requiring low-friction smooth surfaces. | CNC machining, Sheet metal fabrication | Metals, Some hard plastics |
