Despite considerable knowledge of construction machines and proper cutting techniques, we can not eliminate all kinds of problems occurring during work. We present simple examples of the most common mistakes made by operators.
Why the shield overheats excessively?
| No sufficient cooling is provided | Ensure adequate water and check the pumps. When cutting dry, remember to cool at idle, and we should use much shorter and shallower cuts. |
| Incorrect selected blade for the workpiece | We should always use the dial as intended. We recommend choosing blades according to the table of applications. |
| Cutting speed was too high | Reduce feed speed and pressure. |
why does the blade don't want to cut?
| The disc is too hard for the material being processed | The disc should be selected in accordance with the table of applications. |
| Insufficient drive power of the power cutter | Check the V-belt mounting and engine power. |
| Blunt shield | You can try to sharpen the blade by cutting the material with an abrasive structure or replace the disc. |
why does the blade wear excessively?
| The blade is used for purposes other than intended (eg cutting the material with an abrasive structure with a tile disc) | Choose the disc according to the table of applications and consider what we will cut most often. |
| The blade is not sufficiently cooled | Check the pump and clean the water supply system. |
Why is the blade resonating and deforming?
| The pressure of the disc on the material is too large | Reducethefeedspeedand reducethe pressure. |
| The blade overheats during dry cutting | In this case, always remember to periodically cool the disc at idle. |
| The resulting disk stresses | Check the mounting flanges. They may be too small or with different diameters. Always use flanges of the same size. |
Oval wear of the blade?
| Too hard bond | Replace the disc and select it according to the application table. |
| Worn grooves on the drive shaft through the poorly tightened disc | Replace the worn shaft. |
| Worn flanges or shaft | It is recommended to replace worn parts and check that the collar presses the disc properly. |
WHY DO segments fall off during the cutting process?
| The shield is bent | The pressure flanges have probably been worn down. Consider replacing them. |
| Radial run-out | Everything points to a damaged bearing or shaft, it is recommended to repair the power cutter. |
| Cutting speed is too high | Reduce feed speed and pressure. |
WHY DURING THE CUTTING THE DISK blade broke?
| The disc is too hard for the material being processed | Always choose the disc according to the table of applications. |
| Excessive pressure during cutting, frequent wedging or twisting of the blade may lead to material fatigue | Work with even feed and make cuts in a straight line. |
| Cutting speed is too high | Reduce feed speed and pressure. |
| Insufficient water supply, use of dry cutting discs without cooling at idle speed | Water flow when dry cutting. |
WHY DURING CUTTING Segments break?
| The disc is too hard for the material being processed | The disc should be selected in accordance with the table of applications. In this case with a softer binder. |
| Cutting speed is too high | Everything points to a damaged bearing or shaft, it is recommended to repair the power cutter. |
Uneven wear of the segments during cutting
| Insufficient cooling water or poor saw position | Clean the blade cooling system and make sure that the pump is supplying water in the right quantity, then check that the water hits the edge of the blade. |
| Worn shaft, worn bearings, mounting hole on the disc larger than the shaft, dirt or damage to the flanges | Replace the bearings or shaft and check and clean the flanges. |
Undercutting blade, what could be the reason?
| Cutting material with a high abrasive structure | This is a phenomenon that unfortunately we can not completely eliminate. It is recommended to supply more water and use shields with protective segments. |
| Continuous cutting of material, cooling water leaking from the expansion joint (road cutters) | The cutting depth should be reduced (it should be slightly smaller than the thickness of the material being cut). |
The mounting hole has been calibrated?
| Poor setting of the dial | Insert the disc on the shaft correctly and then tighten the mounting flange. |
| Badly mounted flange, so that the blade rotates on the shaft | Tighten the fastening screw. |
| Badly mounted flange, so that the blade rotates on the shaft | It is recommended to replace worn parts and check that the collar presses the disc properly. |
