| Problem | Cause | Correction |
|---|---|---|
| Breakdown of root width poor thread form | Soft, coarse wheel | Use finer, hard wheel |
| Poor coolant flow | Direct coolant to point of contact | |
| Poor diamond dress | Dress from point to edge of wheel, take lighter dress cuts, replace or tighten diamond | |
| Burning or discolored work piece | Poor coolant supply | Redirect to point of contact |
| Too heavy infeed | Reduce infeed | |
| Slow work speed | Increase infeed | |
| Lead error | Wheel deflection (Resin only) |
Use vitrified wheel |
| N/A | Use a thicker resin wheel | |
| N/A | Use larger flanges | |
| Poor finish or chatter | Diamind lines (Even scatches) |
Use slower diamond feed, or lighter feed |
| Rough surface | Lighten, or slow up work speed | |
| High work speed | Slow work speed |
