Troubleshooting Guide
Important Facts
Guides and guide arms
Check and adjust the guides regularly.
Check if worn out and replace if necessary.
Position guide arms as close to the workpiece as possible.
Band wheels
The wheels have to be kept in good condition and should be properly aligned.
Machine | Chip brush | |
| ||
| Check that the chip brush is properly adjusted and | |
| change it regularly. | |
| Band tension | |
| The correct band tension is needed to get a straight cut. | |
| Measure with the Bahco tensionmeter. | |
| Coolant/Cutting fluid | |
| The coolant is needed to lubricate and to cool. | |
| Check the concentration with a refractometer | |
| Use a good coolant. It should reach the cut with | |
| low pressure and with a generous flow. | |
Data | Band speed | |
see chart on page 8. | ||
| The band speed has to be correctly chosen, | |
Cutting | Check the band speed using the Bahco tachometer. | |
Feed rate | ||
| ||
| The feed rate has to be chosen so that the teeth of | |
| the bandsaw blade can work properly, see page 8. | |
| Tooth pitch | |
| The selection of the right pitch of the blade is just as | |
Blade | important as choosing the correct feed and speed. | |
See page 9 and 10. | ||
| ||
| Tooth shape | |
Bandsaw | Every tooth has its ideal application. | |
To select the right one, consult page 11. | ||
| ||
| Running in | |
| A new bandsaw blade should be run in to obtain maximum | |
| bandsaw tool life. (see page 7) Never saw in old kerf. | |
| Blade life | |
| All blades wear out eventually. Look for signs of wear. | |
| Surface | |
Workpiece | The surface quality of the workpiece will strongly | |
influence the life of the blade. If the surface is bad, lower | ||
| ||
| the band speed. | |
| Clamping | |
| Make sure the workpieces are securely clamped. This is | |
| especially important when cutting bundles. | |
| Do not use bent or damaged workpieces. |
