Below are examples of custom CNC milled components manufactured according to customer drawings, including plates, housings, covers and structural parts.
Different CNC milling methods are selected according to part geometry, tolerance requirements, machining surfaces and production quantity. Our team will review your drawings and recommend the most suitable process.
Milling Type | Suitable Parts | Precision Reference | Best For |
3-Axis CNC Milling | Plates, brackets, covers, pockets, slots and simple housings | Commonly ±0.01 mm | Cost-effective standard milled parts |
4-Axis CNC Milling | Multi-side parts, angled holes, cylindrical features and repeat production parts | Down to ±0.005 mm after drawing review | Fewer setups and better consistency |
5-Axis CNC Milling | Complex surfaces, angled features, impellers and high-precision components | Down to ±0.002 mm after technical review | Complex geometry and high-precision machining |
Xintao provides an extensive range of surface finishing options aimed at enhancing the surface characteristics of CNC-Milling parts.
