CNC Machining Surface Finish Capabilities
Anodizing
Type II anodizing improves corrosion resistance and serves as a base for paint and other finishes. Results may vary by material.
• Dyeing available to modify surface color
• Type II coatings are less wear-resistant and may fade under UV exposure
• Custom colors available (RAL chart supported)
Passivation
Passivation is a chemical process that removes free iron from stainless steel surfaces to enhance corrosion resistance without altering appearance.
• Commonly used for stainless steel, especially in medical and food-grade parts
• No coating added; surface remains clear and metallic
• Improves stability of the protective oxide layer
Bead Blasting
Bead blasting uses high-pressure abrasive media (e.g. glass beads) to remove small burrs and create a uniform matte finish.
• Often paired with anodizing to enhance surface texture
• Does not alter part dimensions; ideal for appearance-critical components
• Matte effect may vary slightly by material type
Polishing
Polishing improves surface smoothness through mechanical abrasion, commonly used for decorative or high-tolerance parts.
• Capable of achieving mirror or semi-gloss finishes
• Not suitable for all geometries (e.g. narrow or deep holes)
• Compatible with stainless steel, copper, aluminum, and other metals
Turning Finish
Turning naturally produces concentric tool marks with high dimensional accuracy and a clean mechanical appearance, suitable for industrial parts without additional finishing.
• Directional texture based on tool path
• Surface roughness typically Ra 0.4–1.6 µm
• Can serve as a final finish or pre-treatment for further processing
Knurling
Knurling forms regular diamond or straight patterns by pressing, enhancing grip—commonly used for handles, knobs, and fasteners.
• Suitable for cylindrical metal parts
• Improves slip resistance and prevents loosening
• Pattern depth and style can be customized
Black Oxide
Black oxide is a chemical conversion coating applied to steel to improve corrosion resistance and create a uniform black appearance.
• Commonly used for tools, fasteners, and industrial parts
• Adds minimal thickness; does not affect dimensional fit
• Typically paired with oil to enhance rust protection
Nickel Plating
Nickel plating forms a uniform, dense nickel layer on metal surfaces to enhance wear resistance, corrosion protection, and conductivity—commonly used in electronic, electrical, and mechanical components.
• Available as electroless or electrolytic nickel plating
• Provides either bright or matte finishes
• Suitable for copper, steel, and stainless steel parts

Our CNC Machining Process
A Step-by-Step Guide to Precision Manufacturing
Our engineers start by creating a detailed CAD model of
the part, capturing all necessary specifications, including
dimensions, tolerances, and material properties.
The CAD model is then converted into a CNc program(G
code),which controls the movements and operations of
our machines, ensuring accurate execution of the design.
Once set up, our advanced CNC machines—such as 5-axis machining centers—carry out the material removal process with minimal supervision, shaping the raw material into the final component with precision.
After machining, all parts undergo rigorous inspection to ensure they meet the required tolerances and quality standards. We use advanced measurement techniques to ensure dimensional accuracy and compliance with specifications.
