Machining sample / selection reference
At ZHD Precision, we provide a full range of CNC milling surface finishes that enhance both functionality and appearance, improving durability, resistance to corrosion, and aesthetics as part of our comprehensive CNC machining process.
Selected finish
Anodizing
Finish decision
A dedicated electrochemical oxidation process for aluminum parts. Classified into standard and hard anodizing, it forms a dense protective oxide film to enhance surface corrosion resistance and wear resistance.
Applicable Materials
Full Range of Aluminum Alloys
Surface Color
Available in a variety of colors, including natural, silver, black, blue, and red.
CNC milling tolerances define how precisely part dimensions are controlled during machining.
Our precision CNC milling services follow ISO 2768-m for metals and ISO 2768-c for plastics, delivering stable, repeatable dimensional accuracy across 3-axis, 4-axis, and 5-axis CNC milling.

Process selection is reviewed around geometry, datum relationships, surface condition and the final assembly interface.
Optimize your drawings using our CNC milling design guidelines for wall thickness, corners, cavities, holes, slots, undercuts, coating allowance and curved profiles. Proper design cuts deformation, tool wear and additional expenses, ensuring custom parts with stable tolerances, improved manufacturability, faster lead-time and reduced part costs.
Prevent deformation and machining instability caused by walls that are too thin.
Maintain uniform wall thickness at 1.5–3.0 mm for aluminum parts and 2.0–4.0 mm for steel parts to avoid deformation and machining instability.
Avoid sharp internal corners; use minimum fillet radius ≥ R0.8–R1.5 to match standard end mill tools and reduce tool wear.
Share the CAD model before release so wall thickness, radii, tool reach, finishing allowance and datum strategy can be reviewed together.
