Machine: Factors that influence the blade-life of a band saw blade

The following machines factors make an impact on the blade-life besides breaking-in of a new band saw blade, the blade stability as well as the blade length:

Regular cleaning and maintenance of the machine

• Every time the band saw blade is replaced
• Removal of collections of chips near the saw frame and the band guides
• Check the condition and position of the chip brushes

Condition check of the sawing machine

• Impellers (bearings, contact surface): Shut down the machine and check the distance between the band saw blade and the collar of the impeller
• Condition of the guides
• Band backing guides
• Guide is too long: Deviation of the band saw blade leads to a cutting sequence, possibly a broken band
• Side band guides (flat guide and roller guide)
• Pre-tilt damping rollers

Insert a new band saw blade

• Place the band saw blade with tooth protection on the impellers and feed into the band guides
• Tighten the band saw blade and check the band tension - Recommended band tension: 250 - 300 N/mm²
• Remove the tooth protection and use the band saw blade in idle, set the chip brushes at the same time
• Break-in a new band saw blade
• Band stability, band length
   

Note

Correct band tension is extremely important for the life span of a band saw blade and the precision of the cut. If the band tension is too low, it will lead to a cutting sequence. If the band tension is too high, the band may break
