CNC Machining Surface Finishes
CNC machining surface treatment refers to a series of physical or chemical treatment processes on the workpiece surface after the part is cut by a CNC machine tool (Computer Numerical Control). The main purpose of these treatments is to improve the appearance, function or durability of the parts to meet design requirements and practical application needs.
As Machined1
The surface of the parts formed after processing will have clear processing lines, and usually there will be surface treatments such as deburring and sharp edge removal.
Anodizing
It is the process of forming an oxide film on the metal surface by electrolysis.
Powder coating
The powder coating is sprayed onto the aluminum surface by electrostatic adsorption and cured at high temperature to form a coating.
Black Oxidation
Refers to the process of forming a dense, uniform, microporous black oxide film on the surface of aluminum through electrolysis.
Plating
The process of depositing a layer of metal or alloy on the surface of aluminum by electrolysis to improve conductivity, wear resistance, decorative properties or corrosion resistance.
Sandblasting
It is a pretreatment performed before metal surface preparation, metal priming, painting surfaces or bonding.
Heat Treatment
An important metal processing technology that changes the internal structure of metal parts by heating and cooling, thereby significantly improving their material properties.
Polishing
Chemical or electrolytic polishing to obtain mirror effect, often used for high-gloss parts.
Brushed Finish
A surface treatment method that uses a flat-pressed abrasive belt and a non-woven roller brush to form lines on the workpiece surface to achieve a decorative effect.
Electrophoresis
The electric field is used to deposit charged paint particles on the aluminum surface to form a uniform coating.
Passivation treatment
A surface treatment technology designed to enhance the corrosion resistance of stainless steel and other specific metal materials.
Milling/Grinding
Specific textures or geometric structures are formed by CNC machining or belt sanding.

CNC Machining Design Guidelines
Read our practical guide to optimize production efficiency. Kaierwo experts offer immediate feedback to ensure optimal results in CNC machining.
Feature
Explaination
Part size
Machined parts are limited by the machine envelope. 3 - axis machines usually have a larger build size than multi - axis ones.5 - axis machines, though with a generally smaller build size in some cases, offer greater flexibility for complex - shape machining within their working range.
Feature alignment
For 3 - axis machining, adding features to multiple faces is costlier; aligning features on one face helps.5 - axis machining enables easier and more cost - effective machining of features on multiple faces, reducing the need for strict single - face alignment.
Fillets
Internal fillets should be large (radius > 1/3 cavity depth for 3 - axis) to use large - diameter tools and prevent damage.In 5 - axis machining, the principle holds, but access to complex geometries brings some flexibility, yet sufficient radii to avoid tool damage remain key.
Wall thickness
Metal parts need a minimum 0.8 mm wall thickness, plastic 1.5 mm (3 - axis, as thinner walls vibrate/deform).5 - axis machining may reduce vibration; minimum requirements still apply, but might allow slightly thinner walls in carefully evaluated cases.
Cavity depth
For 3 - axis, cavity depth ≤ 4x width to reduce issues.5 - axis, with shorter tools and better access, can increase depth to 6 - 8x width (depends on material, tooling, geometry).
Holes and threads
For 3 - axis, hole/thread diameters match standard tools, hole depth ≤ 10x diameter.5 - axis can improve deep - hole machining, extending the depth - to - diameter ratio to 12 - 15x in favorable situations (material/tool quality matters).
Undercuts
3 - axis: T - slot undercuts 3 - 40 mm wide; dovetail undercuts best at 45/60 degrees.5 - axis: Handles more complex undercut shapes/angles, expanding design possibilities.
