Surface Treatment for CNC Machined Parts

Surface treatment for CNC machined parts enhances performance, durability, and aesthetics. Common processes include polishing, which smooths surfaces for a shiny finish; anodizing, which increases corrosion resistance, especially for aluminum; and powder coating, providing a durable, decorative layer. Electropolishing improves smoothness and corrosion resistance, while passivation creates a protective oxide layer on stainless steel. PVD and electroplating offer decorative and functional coatings, such as gold or chrome. Other treatments like sandblasting, brushing, and black oxide improve surface texture, while heat treatment strengthens the material. These treatments optimize parts for specific industrial applications.

Suggestions for Low Volume Machining

low volume CNC machining design guidelines emphasize material selection, uniform wall thickness, achievable tolerances, and accessible features. Key principles include avoiding sharp corners, minimizing material removal, and ensuring proper hole design and symmetry to optimize machining efficiency, cost, and part quality.

Items	Suggestions	Reasons
Draft Angle	1° to 3° (depending on material)	Ensures easy removal from molds, prevents part distortion, and aids in molding and casting processes.
Hole Size	Tolerance: ±0.2 mm for small holes, ±0.5 mm for large holes	Achieves proper fit and function, especially for threaded holes or parts requiring tight assembly.
Tolerance Control	±0.05 mm for precision parts, ±0.1 mm for general parts	Ensures parts meet functional requirements, with tight tolerances critical for assembly and fit.
Wall Thickness	1 mm to 5 mm depending on material	Ensures part strength without material wastage and allows for efficient cooling in casting and molding.
Surface Finish	Ra 1.6 to 3.2 µm (for CNC machining)	Achieves smooth surfaces that reduce friction, improve appearance, and ensure proper function.
Radii and Fillets	Minimum radius: 0.5 mm	Reduces stress concentrations, improving strength and durability, especially in load-bearing parts.
Interference Fit	H7 for holes and g6 for shafts	Ensures precise fits for press-fit components, reducing the risk of malfunction and wear.
Corner and Edge Design	Minimum radius: 0.5 mm	Prevents sharp edges, reduces risk of injury or damage during handling, and improves product life.
Assembly Clearances	0.1 mm to 0.3 mm clearance between mating parts	Ensures proper assembly and function without binding or excessive friction between parts.
Stacking & Alignment Features	Use of alignment pins or slots	Guarantees accurate assembly, prevents misalignment during prototype testing or production.
