Having problems with your cutting or grinding processes? Here are some common symptoms and causes of incorrect applications, and how to correct it.
Issue: Cutting surface is blue
| Possible Causes | Solution |
|---|---|
| Cutting time is too long | Inrease feed speed or grinding pressure |
| Drive power is too low | Use a more powerful machine |
| Disc is too hard | Select a softer bond |
| Material cross section is too great for the disc diameter | Work with a saw cut / work with a smaller material diameter |
| Cutting disc is too wide for the material/application | Use a thinner cutting disc |
Issue: Disc wear is too high
| Possible Causes | Solution |
|---|---|
| White cutting surface: disc hardness is too low | Select a harder bond |
| Peripheral speed is too low | Increase peripheral speed |
| RPM decrease is too great | Reduce grinding pressure or use a more powerful machine |
Issue: Crooked Cut
| Possible Causes | Solution |
|---|---|
| Workpiece is not mounted properly | Mount the material closer to the cutting site |
| Grinding pressure is too great | Reduce grinding pressure |
| Disc width is too thin for the material/application | Increase disc width |
| Disc is completely worn down | Replace disc |
Issue: Disc breakage
| Possible Causes | Solution |
|---|---|
| Machine is operated incorrectly | Avoid lateral pressure on the disc |
| Incorrect wheel flange diameter | Use wheel flange with identical diameters |
| Cutting-off wheel is used for grinding | Cutting-off wheels may not be used for grinding! |
| Material is not properly affixed | Mount the material closer to the cutting site |
Issue: Disc periphery is frayed
| Possible Causes | Solution |
|---|---|
| Disc periphery is burned | Select a softer bond, decrease grinding pressure |
| Material is not properly affixed | Mount the material closer to the cutting site |
Issue: Disc jumps
| Possible Causes | Solution |
|---|---|
| Wheel flange is dirty or worn out | Clean wheel flange or replace wheel flange |
| Bearing is defective | Replace machine or replace bearing |
| Bore dimension and mount do not match | Use proper bore dimension or use a reducer ring |
Issue: Bore hole is broken
| Possible Causes | Solution |
|---|---|
| Wheel flanges are of different sizes | Use wheel flanges that have the same diameters |
| Machine is operated incorrectly | Reduce lateral pressure on the disc |
| Cutting-off wheel is used for grinding | Cutting-off wheels may not be used for grinding! |
