Our AS9100D-certified workshops handle components from 1mm to 3m diameter, offering: Surface grinding (0.1-0.8μm Ra finish) Cylindrical grinding (ID/OD capabilities) Centerless grinding (for high-volume production) Tool & cutter grinding (for complex geometries) Jig grinding (for mold precision machining)
What is Grinding Finish?
A mechanical material removal process where:
Abrasive wheels remove microscopic material layers
Achieves ultra-precise dimensional accuracy
Creates superior surface finishes vs conventional machining
Key parameters:
Surface finish: Ra 0.1-0.8μm
Dimensional tolerance: ±0.005-0.02mm
Roundness: ≤0.001mm
Flatness: ≤0.003mm/m
Grinding Advantages
- Ultra-precision - Achieves tolerances impossible with milling/turning
- Superior finish - Reduces friction and wear in moving parts
- Material versatility - Processes hardened steels (HRC 60+), ceramics, composites
- Process stability - Maintains consistency across production runs
- Cost-effective - 30-50% faster than EDM for precision features
Notes
- Material limitations: Not recommended for soft materials
- Pre-treatment: Stress relieving recommended for critical parts
- Post-treatment: Deburring usually unnecessary
- Certification: PPAP documentation available
Grinding Applications
- Aerospace: Turbine blades, fuel nozzles, landing gear components
- Medical: Implant surfaces, surgical instrument joints
