Problem 1: The short lifespan of corrugated board blades.
A : Is the grain size of the grinding wheel adequate?
Too coarse a grain size of grinding wheel? shortens the lifespan/performance time of blades.
B : Excessive grinding : the grinding interval is too short of the grinding pressure is too high.
Problem 2 : The edges of corrugated boards cut by blades show burrs and dents.
A : Please check the cutting edge of your blade.Is the cutting-edge sharp enough？
B : The corrugated board is too wet.

B : Unstable swing grinding wheels break the blades;please check the bearing of the grinding wheels.
C : The problem may be caused by collision with other hard objects.
Problem 4 : Chips on the cutting edge after the grinding.
A : Unstable swing grinding wheels may cause this problem , even break the blades .
B : A collision with hard objects may cause the chips on the cutting edge.
