Common problem and solution for cut-off wheel

Solution
● The cutting wheel consumption fast
Select and adopt the models with high hardness level
Decrease the grinding pressure
● The inner bores of cutting disc craze
Move forward and backward evenly, and exert pressure along the diametrical direction.
Use the grinding disc in grinding process.
Avoid to exert pressure in side direction.
Apply the flange plate with the same diameter in inner side and outer side.
● The edge crazes while the abrasion wheel is cutting
Replace the flange plate with large diameter and generally the diameter of flange plate should be required to reach 1/3 of that of the abrasion wheel.
Adjust the pressure of the flange and abrasion wheel to a reasonable level.
Decrease the load while cutting and reduce the pressure inside direction.
Replace the flange plate with large diameter and generally the diameter of flange plate should be required to reach 1/3 of that of the abrasion wheel.
● The fracture of workpieces is burnt severely
Adopt the abrasion wheel of low hardness level and high efficiency.
Replace it with high work rate.
Adjust the tightness of the belt.
Adopt the abrasion wheel of low hardness level and high efficiency.
