Gang Saw Blades Trouble Shooting

Problem Solution
Defaults with sawn slabs
Cutting deviations
  • check verticality of the blades
  • check parallelism of the blades to stroke direction
  • check deflection of the blades
  • check tension of the blades
  • check condition of the segments
  • sharpen blades
  • increase down feed
Chatter marks
  • check amount of water
  • check deflection of blades, possibly increase
  • check tension of the blades
  • increase down feed slightly, especially when starting with new blades
  • segment-spacing (change graduation)
Defaults with the gang saw blades
Excessive wear at one end of the blade
  • check horizontal fixing of the blades
Excessive wear at both ends of the blade
  • increase deflection
  • increase segmented length or reduce block lengths
Excessive wear at the centre of the blade
  • reduce deflection
  • choose smaller segment-spacing or use longer blocks
  • increase water supply
Insufficient output
  • increase water supply
  • use longer blocks
  • choose smaller segment-spacing
  • damaging machine vibrations (contact machine manufacturer)
  • check fixing of the block
