Band Saw Trouble Shooting Chart

Blade Effect

Probable Cause

  • Incorrect Blade
  • Band tension too high
  • Excessive Feed
  • Incorrect Cutting Fluid
  • Wheel diameter too small for blade width
  • Wom or chipped pressure block
  • Blade rubbing on Wheel Flange
  • Teeth in contact with work before starting saw
  • Side guides too tight

Solution

  • Check tooth selection
  • Reduce band tension, refer to operators manual
  • Reduce feed pressure
  • Check coolant recommendations
  • Use narrower blade
  • Replace wom pressure blocks
  • Adjust wheel alignment
  • Allow blade clearance above work
  • Refer to operators manual
  • Blade on machine backwarde
  • Improper blade break-in procedure
  • Hard material or heavy surface scale
  • Material is work hardening
  • Improper cutting fluid or mix ratio
  • Speed or feed too high
  • Install blade correctly
  • Refer to recommended procedures
  • Check material hardness and surface condition
  • Increase feed pressure
  • Follow coolant mixing procedues
  • Check cutting recommendations
  • Worn or missing chip brush
  • Improper or lack of cutting fluid
  • Wrong coolant ratio
  • Excessive feed or speed
  • Incorrect blade pitch
  • Replace or adjust chip brush
  • Check coolant flow and fluid type
  • Check coolant type and ratio
  • Reduce feed or speed Use proper tooth
    selection
  • Indexing while blade in work
  • Blade not high enough before index
  • Saw head drifts into work while neutral
  • Adjust index sequence
  • Adjust height selector
  • Check hydraulic cylinder
  • Excessive back-up guide preload
  • Low blade tension
  • Incorrect blade (carbon steel type)
  • Excessive feed rate or pressure
  • Damaged or wom pressure block
  • Guide arms spaced too far apart
  • Blade rubbing band wheel flanges
  • Adjust pressure blocks
  • Refer to operators manual
  • Switch to a Bimetal blade
  • Reduce feed rate or pressure
  • Replace pressure block
  • Adjust guide arms closer to work
  • Adjust wheel alognment
  • Blade binding in cut
  • Side guides are too tight
  • Work loose in vies
  • Feed to heavy
  • Guide arms too far apart
  • Adjust feed or use heavy set blades
  • Adjust guides
  • Adjust vises
  • Reduce feed pressure Adjust guide arms closer to
    material
  • Incorrect blade
  • Heavy feed too fast speed
  • Lack of cutting fluid
  • Blade installed backwards
  • Use proper tooth selection
  • Refer to cutting recommendations
  • Adjust coolant flow or ratio
  • Install blade correctly
  • Material loose in vise
  • Incorrect tooth pitch
  • Feed too fast
  • Speed too fast
  • Adjust vises
