Machine is: Koyo C4520F (Centerless Grinder)
Blade is looking good. Grinding Wheel and Regulating Wheel are new on the machine.
We are grinding the whole parts but sometimes we have a flat surface on the whole ground diameters.
Process is: Loader is picking part up - RW is staying during Grinding on same Position - Loader moves part on blade - GW is starting with grinding; after finishing the GW is moving back & Loader is going up to Home Position.
When we check the part we see a flat on the part sometimes.
Don't know why and how to prevent the flat.
Need Help please
