Troubleshooting Guide
PROBLEM
Segment acting too hard
Segment acting too soft
Glazing and/or burning
CORRECTION
Increase rate of downfeed
Increase table rotation speed (watch amp-meter)
Dress more frequently
Consider reducing area of table load
Decrease rate of downfeed
Decrease table rotation speed
Check for abnormal machine vibration
Choose a softer grade
Increase table speed (watch amp-meter)
• Choose as coarse a grit size as possible in order to remove
stock as quickly as possible (in big chips).
• To maximize production, choose the hardest grade possible
that will not overload the machine.
