Life-time of band saw blades mainly depends on a controlled break-in.
We recommend the following break-in procedure:

1.
1st step

Select the correct speed Vc (m/min) and cutting rate Vz (cm /min) based on cutting conditions chart.

2.
2nd step

You start with 70% of the regular cutting speed and 50% of the regular cutting rate.

3.
3rd step

If vibrations still occur, change the speed carefully until the vibrations stop. A permanent chip formation is important during the whole cutting process.

4.
4th step

After cutting approx. 400-600 cm2 or at least 15 minutes real cutting time for tubes and profiles you can first slowly turn up to the final speed and then up to the normal cutting rate.
