1. The joint between the base body and the cutter head is worn
Reason: The material to be cut is very wear-resistant, and the cutting debris is mixed in the cut and cannot be discharged.
Solution: Use protective teeth in special positions on the substrate and use a cooling water flow with a higher pressure to enhance the chip evacuation effect.
2. The wear on both sides of the cutter head is uneven
Reason: Blade oblique cutting; The amount of water on both sides is not the same, and one side does not have enough water.
Solution: Check the inclination of the saw blade; Check the cooling water system.
3. The saw blade is out of circle
Cause: Shaft wear resulting in large clearance between the center hole of the saw blade and spindle or incorrect installation.
Solution: Replace the worn shaft or repair the center hole.
4. Saw blade deflection
Reason: The debris of the cut material is mixed in the cutting seam, which causes uneven force on the body; The diameter of the flange is too small or the diameter of the flange on both sides is inconsistent; There are foreign objects between the saw blade and the flange disc; Not installed properly.
Solution: Clean up the debris and enhance the chip removal effect; adjust or replace the flange; Follow the instructions to install it properly.
5. Broken bits
Reason: The bits are too hard; The saw blade feed rate is too fast.
Solution: Choose a saw blade with a softer bond according to the material to be cut; Reduce the feed rate of the saw blade.
6. The cutter head wears out too quickly
Causes: The bits are too soft (for the material to be cut); insufficient amount of cooling water; Insufficient power due to loose transmission belt or low voltage or improper speed; The saw blade is not perpendicular to the material being cut.
Solution: Select a saw blade with a harder binder according to the material to be cut; Check the cooling water system to ensure that the water pump is operating properly; Ensure the supply voltage; Check the spindle flange to ensure the verticality of the saw blade and the equipment; Check the rotational speed of the saw blade.
7. Loss of cutter head
Reason: The cutter head is twisted off by the sliding of the cut material during the cutting process; Subjecting the cutter head to a heavy blow; The flange is worn and cannot fix the saw blade, resulting in the distortion of the saw blade; The unrounding of the saw blade caused by the wear of the spindle makes the saw blade subject to a large impact; Superheating; The saw blade was subjected to a violent impact.
Solution: Firmly fix the cut material when cutting; Replace the flanges on both sides; replacement of worn spindles; Check the cooling water; Avoid hitting the saw blade when moving the device or the material being cut.
8. Blunt and cannot be cut
Reason: The saw blade binder is too hard; The lack of power is not able to make the saw blade cut normally, and the saw blade is not applied enough cutting pressure; The saw blade line speed is too high.
Solution: Choose a saw blade with a softer binder; Check the drive belt, voltage and motor; Make sure that an adequate and not too large cut-in pressure is used; According to the instruction manual of the equipment, select the corresponding diameter of the saw blade that matches it.
