Grinding
When and where required (accurate geometry or size) after sintering
With help of a diamond wheel
After grinding :
Shape defect 10 to 50 microns (typical 20 microns PTV on a 1350 mm
diameter)
Planarity of a few microns
Typical Ra roughness 0.3 microns
Grinding machines capacity :
Flat : 2 x 0.9 m
Circular : diameter 3.5 m
