Precision Machining Services for Investment Castings: Your One-Stop Manufacturing Solution

Comprehensive Machining Capabilities

At China Metal Castings, we specialize in high-precision machining services to complement our investment casting expertise. Our state-of-the-art machine shop offers:

✔ CNC Turning & Milling (3-axis to 5-axis)
✔ Multi-Surface Grinding (OD/ID/Surface)
✔ Specialized Processes: EDM, Broaching, Thread Grinding
✔ Secondary Operations: Drilling, Tapping, Slotting, Reaming

Why Machining Matters for Cast Components?
Machining transforms raw castings into ready-to-assemble precision parts by:

• Achieving tighter tolerances (up to ±0.001″)

• Creating critical sealing surfaces

• Adding threads, blind holes & complex geometries impossible via casting alone
