Custom Parts for Industrial Machinery are precision-manufactured components for OEMs, equipment builders and maintenance operations, produced with capabilities ranging from ultra-high precision finishing to large-format machining. Hansheng provides build-to-print manufacturing, advanced gear production and complex-geometry solutions for a wide variety of industrial applications.

Core capabilities

• Ultra-high precision machining: standard CNC turning/milling to ±0.01 mm, precision grinding to ±0.005 mm, and ultra-mirror finishing to ±0.002 mm.
• Advanced gear manufacturing: in-house skiving and hobbing (Kashifuji KPS30, Ningjiang YK3610Ⅳ) producing internal and external gears with gear profile inspection.
• Large-scale horizontal machining: heavy-duty horizontal machining centers capable of processing workpieces up to 2100 mm x 1060 mm for monolithic bases and large housings.
• Complex geometry solutions: Seibu Wire EDM (M50B) and 5-axis milling for intricate contours, hardened steels and conductive materials.
• Reverse engineering and CAD file support: typical accepted file formats include STEP (.stp), IGES (.igs), X_T, SolidWorks and 2D PDF drawings with tolerances.
