Having problems with your cutting or grinding processes? Here are some common symptoms and causes of incorrect applications, and how to correct it.
Possible CausesSolution
Cutting time is too longInrease feed speed or grinding pressure
Drive power is too lowUse a more powerful machine
Disc is too hardSelect a softer bond
Material cross section is too great for the disc diameterWork with a saw cut / work with a smaller material diameter
Cutting disc is too wide for the material/applicationUse a thinner cutting disc
Possible CausesSolution
White cutting surface: disc hardness is too lowSelect a harder bond
Peripheral speed is too lowIncrease peripheral speed
RPM decrease is too greatReduce grinding pressure or use a more powerful machine
Possible CausesSolution
Workpiece is not mounted properlyMount the material closer to the cutting site
Grinding pressure is too greatReduce grinding pressure
Disc width is too thin for the material/applicationIncrease disc width
Disc is completely worn downReplace disc
Possible CausesSolution
Machine is operated incorrectlyAvoid lateral pressure on the disc
Incorrect wheel flange diameterUse wheel flange with identical diameters
Cutting-off wheel is used for grindingCutting-off wheels may not be used for grinding!
Material is not properly affixedMount the material closer to the cutting site
Possible CausesSolution
Disc periphery is burnedSelect a softer bond, decrease grinding pressure
Material is not properly affixedMount the material closer to the cutting site
Possible CausesSolution
Wheel flange is dirty or worn outClean wheel flange or replace wheel flange
Bearing is defectiveReplace machine or replace bearing
Bore dimension and mount do not matchUse proper bore dimension or use a reducer ring
Possible CausesSolution
Wheel flanges are of different sizesUse wheel flanges that have the same diameters
Machine is operated incorrectlyReduce lateral pressure on the disc
Cutting-off wheel is used for grindingCutting-off wheels may not be used for grinding!
