Troubleshooting Guide
| PROBLEM | POSSIBLE CAUSE | SUGGESTED CORRECTION |
| POOR STOCK REMOVAL | Insufficient pressure applied wheel too coarse or hard inadequate abrasive | Increase pressure to use all available power,use finer grit and/or softer grade wheel |
| Grinding costs too high | Wheel acting too soft,low performance specification | Use harder and/or coarser wheel |
| Wheel loading or glazing | Grade too hard,grit too coarse,dirty,scale-covered parts | Try softer grade Try finer grit |
| Wheel dusty | Wheel too soft | Use harder grade |
| Wheel doesn\'t hold corner or wheel spalling | Wheel too coarse Wheel too soft | Use harder grade Use finer grit |
| Burning the workpieces | Wheel too hard Wheel glazed or loaded Grinding pressure too low Grinding pressure too high | Use softer grade Dress the wheel face Increase grinding force Reduce grinding force |
| Surface finish to rough | Wheel too coarse Wheel speed too low Worn machine bearing | Try finer grit Try higher speed machine(do not exceed the max. Operating speed of wheel Rebuild the machine |
| vibration | Wheel worn out of round Fault flanges Bent machine spindle Worn machine bearing | Try dressing the wheel Check flanges for flatness and burrs Check spindle run-out Rebuild machine |
| Wheel stalls or slows | Grinding force too high Wheel too hard Machine power too low | Reduce pressure or contact area Use softer grade wheel Replace machine with higher power grinder |
