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 |
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 |
