SAW BAND TEETH STRIPPING: (usually caused by chip welding)
Saw band pitch too coarse for thin work section.
Work not held firmly to stop vibration.
Feed pressure too high.
Band speed too low.
PREMATURE DULLING OF SAW BAND TEETH:
Not breaking in saw band on first few cuts. Reduce feed pressure and speed on first
(2) Band speed too high, causing abrasion. Reduce speed.
(3) Saw band pitch too coarse.
(4) Wrong type coolant or no coolant used.
(5) Feed pressure too light. Increase feed.
(6) Coolant not covering saw band.
(7) Cutting rate too high.
(8) Faulty material such as heavy scale, inclusions, hard spots, etc.
(9) Material analysis incorrect.
(10) Saw band vibration.
(11) Chipped tooth lodged in cut.
(12) Chip welding.
(13) Operator's error.
(14) Inserts too large for blade width, allowing inserts to hit set teeth.
MOTOR RUNS BUT BAND DOES NOT MOVE:
(1) Broken drive belts or belts off pulleys.
(2) Over-oiling of variable pulley, excess oil has coated pulley and belts.
(3) Drive belt tension too low.
(4) Wrong size drive belts.
(5) Band tension incorrect.
(6) Transmission bad.
BAND SLIPS OFF WHEELS:
Upper wheel not aligned correctly, band does not track on center of wheel tire.
Too much coolant used or wrong type coolant used, causing band to slip off wheel
(3) Initial machine alignment wrong. See Chapter 1.
