CNC Milling Services

CNC milling is commonly used for prismatic and multi-sided parts such as housings, brackets, plates, fixtures and components that require controlled faces, pockets, slots or hole patterns. Final process selection depends on part geometry and drawing requirements.

Common options include aluminum, stainless steel, carbon steel, brass, copper, titanium and engineering plastics such as ABS, POM, nylon, PEEK, polycarbonate and acrylic. Material selection should consider mechanical requirements, machinability, finish and application conditions.

Tolerance capability depends on material, geometry, part size and individual features. For drawing-controlled metal features, certain dimensions may be evaluated down to ±0.01 mm where applicable. Final tolerances are confirmed after engineering drawing review.

CNC milling cutters are round rotating tools, so they cannot directly machine an absolute sharp 90-degree internal corner. Adding an appropriate internal radius improves tool access and can avoid unnecessary secondary operations.

A 3D CAD model is useful for geometry review, while a 2D engineering drawing should be supplied when the project includes critical tolerances, threads, surface requirements or other controlled dimensions.
