Concave wear

When you see a concave wear ring around the blade, it is typically caused by excessive side-load established during operator set up, vibration from the speed of the material running between the blades, or from excessive run-out. Side-load, the most common cause, is the amount of force used to get the upper and lower blade to come into contact. Side-load is often determined by operator instinct, where the operator has a tendency to increase side-load whenever a slitting issue is encountered or an adjustment is desired. This can lead to excessive side-load, which actually makes your slit quality worse and degrades blade life.
