ROLL GRINDING METHOD AND REST Russian patent published in 2006 - IPC B24B1/00 B24B5/04 B23Q1/76 

FIELD: machine tool manufacture, possibly grinding articles such as rolls of rolling mill or paper making machine.

SUBSTANCE: roll with bearing assemblies is mounted in supporting base of rest with possibility of free motion towards tool by means of two devices rigidly joined with bearing assemblies. Worked surface of roll is based on horizontal correcting multi-step supports of rest that are arranged near bearing assemblies. Members of correcting supports are inclined by angles whose values are selected according to condition of guaranteed correction of harmonic components of non-roundness of profile in predetermined range of their spectrum. With use of tool onto rotating roll under one bearing assembly collar is formed with preset parameters of non-roundness. Under second bearing assembly similar collar is formed. At each revolution of shaft non-roundness is corrected. Then the whole working surface of roll is worked.

EFFECT: reduced non-roundness of roll surface, enhanced efficiency of working.
