ABSTRACT:
The work rolls of a planetary rolling mill are subject to high wear and must, therefore, be frequently reground to assure precision of the material rolled. With a life of the work rolls of about six hours, the expenditure of about 12 hours of a mechanic solely for the removal and reinstallation of the 48 rolls of a roll frame represents a considerable cost factor. To substantially reduce the time and expense of regrinding, a complete planet roll with cages and chocks is removed from a roll stand and clamped into a grinding device having a grinding wheel, and then the work rolls are ground, one after the other, in an installed state.
