Precision CNC machining services in Hefei including milling, turning, EDM, and grinding for prototype and production components.
Hefei has a well-developed CNC machining industry serving local manufacturers across automotive, electronics, medical devices, and industrial equipment sectors. Machine shops in Hefei offer a comprehensive range of precision machining capabilities with experienced programmers and machinists.
CNC machine shops in Hefei typically offer 3-axis, 4-axis, and 5-axis CNC milling centers capable of handling parts from small precision components to large structural parts up to 2000mm. CNC turning centers with live tooling enable complete part processing in a single setup. Wire EDM and sinker EDM are available for hardened materials and complex cavity geometries.
Machine shops in Hefei work with a wide range of materials: aluminum alloys (6061, 7075, 2024), steel (1018, 4140, 4340, A2, D2, H13), stainless steel (303, 304, 316, 17-4PH), titanium (Grade 2, 5), brass, copper, bronze, and engineering plastics (Delrin, Nylon, PEEK, PTFE).
Standard machining tolerances are ±0.05mm for most features. Precision machining achieves ±0.01-0.025mm. Tightest tolerances (±0.005mm) are available for critical features using jig grinding and wire EDM processes.
Many CNC shops in Hefei offer additional services including surface finishing (anodizing, passivation, powder coating, plating), heat treatment, assembly, and inspection with CMM and optical measurement systems.
