| Problem | Cause | Correction |
|---|---|---|
| Chatter in Radii | Poor quality coolant | Check coolant concentrator |
| Dull diamond in radii attachment | Check and replace | |
| Work head speed too high | Slow work head speed | |
| Too high stock removal | Reduce stock removal rate | |
| Flats Generated on Diameter | Wheel too hard | Use softer cutting wheel |
| Wheel out of balance | Balance wheel | |
| Steady rest deflection | Ensure rigid steady rest | |
| Poor Finish | Wheel too coarse or too soft | Use harder grade and/or finer grit |
| Improper wheel dressing | Use sharp, rigidly held diamond tool with point contact below center |
|
| Dress traverse too fast | Dress wheel finer | |
| Thrust Face Burning | One side burning - poor diamond dressing | Redress and/or redress at increased infeed |
| Both sides burning - poor diamond dressing | Use corner diamond dress & check for worn diamond | |
| Thrust Face Poor Geometry (stepped/taper) | Wheel too soft | Use harder acting, better corner holding wheel |
| Workspeed too high | Workspeed too high - Slow work speed | |
| Wheel speed too low | Increase wheel speed, check correct pully | |
| Tapered wall wheel too hard | Use softer acting wheel |
