| REAMERS TROUBLESHOOTING |
| Situation |
Causes |
Solution |
| Chatter |
Spindle run-out, Set-up, Operating parameters |
Minimize spidle run-out, Extremely right set-up, Decrease he
cuting speed and increase the feed rate
|
| Premature tool wear
|
Inappropraite material stock left in hole |
Approximately 3% of the reamer diameter should be left in
the hole
|
Flutes chipping, clogging,
or poor surface finish
|
Too much material stock left in hole. |
Use constant flow coolants |
