CNC Milling
Machining centers, CNC mills, gantry mills
High-precision CNC milling for complex geometries, mechanism parts, and mold components. With 40+ years of shop-floor experience, we tailor tooling strategy and machining sequence to control deformation and meet tight tolerances.
Typical projects include: semiconductor vacuum chamber parts, robot joint mounts, mold mounting plates, production-line jigs, and structural brackets. For thin-walled parts, deep internal cavities, or multi-angle mating surfaces, we can integrate EDM or precision grinding to meet final tolerance.
Equipment
- Vertical / horizontal machining centers
- 3-axis and 4-axis CNC mills
- Gantry mill (suited for large structural parts)
- High-speed CNC mill (for aluminum volume production)
Applicable Parts
- Semiconductor equipment mechanisms, vacuum chamber parts
