Problem Cause Correction
Burn Roll speed too slow Increase roll RPM
Wheel too hard Reduce wheel speed, use softer grade
Wheel needs dressing Dress wheel open with plenty of coolant
Chatter Spindle bearing failure Check bearings for quality and alignment
Roll speed too fast Reduce roll speed until vibrations stops
Inadequate lubrication of roll necks Pour oil on roll necks, check condition of work rests
Wheel too hard Reduce wheel speed, use softer grade
Poor quality finish Contaminated coolant Filter coolant and clean regularly
Grit collection in guard Clean and flush inside guard periodically
Traverse too fast Reduce traverse rate
Poor wheel dressing Dress correctly before finish operations - use adequate coolant before dressing
Roll speed too slow Increase roll RPM
Infeed too heavy Reduce infeed for last few passes
