New bandsaw blades require a breaking in period before they are able to withstand the cutting forces and perform at maximum cutting capacity. This break in period is fundamental for honing a micro-fine radius on the tooth tip which prolongs blade life and reduces vibration.
To perform the break in the blade speed must be reduced from the original reference parameter given for the specific material and blade type to eliminate vibrations. If by reducing the speed you still encounter vibration, continue to slow the blade down until the vibrations disappear. Adjustment of the feed rate, instead, should be reduced as a percentage of the blade speed. The correct feed rates can be calculated using the SEKTOR CUTTING EXPERT.
The SEKTOR CUTTING EXPERT program has options for blades which are already prepared with the BREAK-IN or HONING treatments:
BREAK-IN treatment: A pre-treatment on the cutting teeth using tiny particles to lightly remove the finely-honed edge promoting the initial cutting ability for ductile metals, nickel alloys and wood.
HONED treatment: A pre-treatment on the cutting teeth using tiny particles to completely remove the finely-honed edge producing a micro-fine radius perfect for efficient cutting of annealed and tempered steel.

EXAMPLE OF THE BREAK IN PROCESS:
MATERIAL: AISI 316 DIAMETER: 400 MM
REFERENCE PARAMETERS:
BLADE SPEED: 60 m/min FEED RATE: 12 mm/min
BREAK-IN PARAMETERS:
BLADE SPEED: 42 m/min FEED RATE: 6 mm/min
After 30 minutes of cutting gradually increase step-wise first the blade speed followed by the feed rate as follows: 45-7, 48-8, 51-9, 54-10, 57-11, 60-12 obtaining after a few minutes the desired reference speeds.
