Cutting Deviations
| Cutting deviations |
| Check verticality of the blades |
| Check parallelism of the blades to stroke direction |
| Check deflection of the blades |
| Check tension of the blades |
| Check condition of the segments |
| Sharpen blades |
| Increase down feed |
| Check amount of water |
| Insufficient output |
| Increase water supply |
| Use longer blocks |
| Choose smaller segment-spacing |
| Damaging machine vibrations (contact machine manufacturer) |
| Check fixing of the block |
| Chatter marks |
| Check deflection of blades, possibly increase |
| Check tension of the blades |
| Increase down feed slightly, especially when starting with new blades |
| Segment-spacing (change graduation) |
| Excessive wear at one end of the blade |
| Check horizontal fixing of the blades |
| Excessive wear at both ends of the blade |
| Increase deflection |
| Increase segmented length or reduce block lengths |
| Excessive wear at the centre of the blade |
| Reduce deflection |
| Choose smaller segment-spacing or use longer blocks |
| Increase water supply |
Chatter Marks
| Check deflection of blades, possibly increase |
| Check tension of the blades |
| Increase down feed slightly, especially when starting with new blades |
| Segment-spacing (change graduation) |
Excessive Wear at One End of the Blade
| Check horizontal fixing of the blades |
Excessive Wear at Both Ends of the Blade
| Increase deflection |
| Increase segmented length or reduce block lengths |
Excessive Wear at the Centre of the Blade
| Reduce deflection |
| Choose smaller segment-spacing or use longer blocks |
| Increase water supply |
Insufficient Output
| Increase water supply |
| Use longer blocks |
| Choose smaller segment-spacing |
| Damaging machine vibrations (contact machine manufacturer) |
| Check fixing of the block |
