- Wear at the joint of matrix and tool head
Reason: the material is very abrasion – resistant, cutting debris inclusion in the slot can not be discharged.
Solution: the use of protective teeth in special positions of the matrix, the use of high pressure cooling water flow can enhance the effect of chip removal.
- Uneven wear on both sides of the tool head
Reason: saw blade oblique cutting; The amount of water on both sides is different, and there is insufficient water on one side.
Solution: check the tilt of the saw blade; Check cooling water system.
- The saw blade is out of round
Reason: the center hole of the saw blade and the spindle clearance are large due to shaft wear or improper installation.
Solution: replace worn shaft or repair center hole.
- Saw blade deflection
Reasons: the material debris inclusion in the slit caused the body force uneven; The flange diameter is too small or the flange diameter on both sides is inconsistent; There is a foreign body between the saw blade and the flange; Not installed correctly.
Solution: clear debris and enhance the effect of chip removal; Adjust or replace the flange; Install correctly according to instructions.
- Damaged knife head
Reason: the blade binding agent is too hard; Saw blade feed speed is too fast.
Solution: choose the saw blade with soft binder according to the material to be cut; Reduce the feed speed of the saw blade.
- The tool head wears away too fast
Reason: the knife head bond is too soft (for the material being cut); Insufficient cooling water; Power shortage due to loose belt or low voltage or improper speed; The saw blade is not perpendicular to the material being cut.
Solution: according to the material is cut to choose the use of a harder mixture of the saw blade; Check the cooling water system to ensure the normal operation of the pump; Ensure supply voltage; Check the flange of the spindle to ensure the verticality of the saw blade and equipment; Check the speed of the saw blade.
- The knife head is lost
Reason: during the cutting process, the cutting material slides to twist off the tool head; To whack the head of a knife; whack. Flange wear can not fix the blade, resulting in blade distortion; The circular loss of the saw blade caused by the wear of the spindle makes the saw blade suffer great impact. Overheating; The saw blade came under heavy impact.
Solution: firmly fix the material to be cut when cutting; Replace the flange plates on both sides; Replace the worn spindle; Check cooling water; Avoid bumping the saw blade when moving equipment or cutting materials.
8, blunt, not cutting
Reason: the saw blade binding agent is too hard; Insufficient power can not make the blade cut normally, the blade is not applied enough cutting pressure; Excessive blade speed.
Solution: choose a saw blade with a softer binder; Check the belt, voltage and motor; Ensure adequate and not excessive cutting pressure is used; According to the instruction of the equipment to choose the corresponding matching.
