BREAKING IN YOUR BAND SAW BLADES

Sharp cutting edges that have extremely small edge radii are the ideal prerequisites for high cutting ability and a long service life. This is ensured by breaking in the blades properly. See pictures above:

  1. New cutting edge with a very small edge radius
  2. Proper breaking in of the band saw blade creates a stable cutting edge
  3. Excessive strain due to improper breaking in leads to micro-breakages of the cutting edge

 

Before you use them for the first time:

BIMETAL BAND SAW BLADES

  • Determine the right cutting speed and feed rate (using the WIKUS bimetal cutting data slide rule, for instance) based on the material to be cut and its dimensions.

  • Important: Use a new blade with approx. 100% of the cutting speed (m/min) and approx. 50% of the feed rate  (mm/min)

 

CARBIDE BAND SAW BLADES

  • Determine the right cutting speed and feed rate (using the WIKUS carbide cutting data slide rule, for instance) based on the material to be cut and its dimensions.
  • Important: Use a new blade with approx. 75% of the cutting speed (m/min) and approx. 50% of the feed rate (mm/min)
  • Very important: band saw blades can be prone to vibration and vibration noise - Help: To resolve this issue, reduce the cutting speed (m/min) once again

 

  • With small workpiece dimensions, approx. 300 cm² of the material should be cut to break in the blade.
  • With large workpiece dimensions, we recommend breaking in over a period of about 15 min.
  • After breaking in, slowly increase the cutting speed (m/min) to the determined value and then gradually increase the feed rate (mm/min) to the value that you determined before.
