Grinding / Finishing phase
To grind / finish the profile previously created with the grinding wheel:
1)
Use a grinding wheel with the same radius as that of the grinding wheel used for removal.
2)
Perfect positioning of the grinding wheel so that it copies the shape previously created.
3)
The amount of material removed should not exceed 2/10 of mm (0,008 inches).

Polishing phase
Before polishing, it is essential to perform the grinding / finishing operations
In order to maintain the grinding wheels in good working condition:

Perfect positioning of the grinding wheel so that it copies the shape previously created.
3)
The grinding wheel must maintain minimum contact with the material. The amount of material removed should not exceed
1/100 of mm (0,00004 inches).
4)
Cooling water must be clean. Suspended dust resulting from the operations previously performed may damage the
