Too coarse grain size of grinding wheel: make a short working life time of knives
2. The edges of corrugated boards cut by knives with burr and dent
Please check the cutting edge of your blade. Is the cutting edge keen enough
the corrugated board is too wet ?
3. Break of knife
1) Improper assembly will cause the quick break of blades. Any improper touch of the

1) Unstable swing grinding wheels may cause this problem ,even break the knives
2) The strike of hard things may cause the chips on the cutting edge
5.The edge of corrugated board is not straight
Unmatched strength of knives for the corrugated board with high density
