Wear On One Side Of Teeth

Only one side of teeth has heavy wear markings. Probable Cause : Worn wheel flange, allowing side of teeth to contact wheel surface or improper tracking on flangeless wheel. Loose or improperly positioned side guides. Blade not perpendicular to cut. Blade rubbing against cut surface on return stroke of machine head. The teeth rubbing against...

Body Breaking – Fracture Traveling In An Angular Direction

The fracture originates in the gullet and immediately travels in an angular direction into the backing of band. Probable Cause: An excessive twist type of stress existed. Guide arms spread to capacity causing excessive twist from band wheel to guides. Guide arms spread too wide while cutting small cross sections. Excessive back-up guide “preload”. Back

Butt Weld Breakage

To determine if the band broke at the weld, inspect the sides at the fracture to see if there are grind markings from the weld finishing process. Probable Cause : Any of the factors that cause body breaks can also​ cause butt weld breaks. Visit #5 Visit #15 Visit #16 Back

Discolored Tips Of Teeth Due To Excessive Frictional Heat

The tooth tips show a discolored surface from generating an excessive amount of frictional heat during use. Probable Cause : Insufficient sawing fluid due to inadequate supply,​ improper ratio and/or improper application. Excessive band speed. (Learn more) Improper feeding rate. (Learn more) Band installed backwards. Back

Gullets Loading Up With Material

Gullet area has become filled with material being cut. Probable Cause: Too fine of a tooth pitch – insufficient gullet capacity. Excessive feeding rate producing too large of a chip. Worn, missing or improperly positioned chip brush. Insufficient sawing fluid due to inadequate supply,​ improper ratio and/or improper application. Back

Chips Welded To Tooth Tips

High temperature or pressure generated during the cut bonding the chips to the tip and face of teeth. Probable Cause : Insufficient sawing fluid due to inadequate supply,​ improper ratio and/or improper application. Worn, missing or improperly positioned chip brush. Improper band speed. Improper feeding rate. Back

Tooth Strippage

Section or sections of teeth which broke from the band backing. Probable Cause: Improper Tooth Pitch. #1 Cause of tooth strippage Improper or lack of break-in procedure. Worn, missing or improperly positioned chip brush. Excessive feeding rate or feed pressure. (Learn more) Movement or vibration of material being cut. Section or sections of teeth which broke from...

Chipped Or Broken Teeth

A scattered type of tooth breakage on tips and corners of the teeth. Probable Cause : Improper break-in procedure. (Learn more) Improper blade selection for application. (Learn more) Handling damage due to improper opening of folded band. Improper positioning or clamping of material.  Excessive feeding rate or feed pressure. (Learn more) Hitting hard spots or hard scale in material. Back

Wear On Both Sides Of Teeth

The wear on teeth is smooth across the tips and the corners of set teeth have become rounded. Probable Cause : Broken, worn or missing back-up guides allowing teeth to contact side guides. Improper side guides for band width. (Learn more) Backing the band out of an incomplete cut. Back
