Break-In Procedures

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

1st Step: Select the correct speed Vc (m/min) and cutting rate Vz (cm/min) based on cutting conditions chart
2nd Step: You start with 70% of the regular cutting speed and 50% of the regular cutting rate
3rd Step: If vibrations still occur, change the speed carefully until the vibrations stop. A permananet chip formation is important during the whole cutting process.
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.

Above cutting chart refers to average settings. Figures might differ depending on blade type, band saw machine type, condition of thematerial to be cut (surface, heat treatment, standard, ...) and the required cutting specification (tolerances, service life, ...). Please notice that the ultimate service life can only be achieved after correct break-in. If your material is not listed please do not hesitate to contact us for further information.
