The causes of blade wear in slitters.
To determine the cause of slitter blade wear, look for the tell-tale signature wear patterns on blades that will help you differentiate between blade-to-blade wear, and web-to-blade wear.
Once the distinctive patterns of wear are classified, the solutions will be easier to recognize and implement without resorting to "taking a stab in the dark"' or applying an unnecessarily costly solution to a relatively simple problem.
A general rule of thumb for general-purpose slitting is that the texture of a slitter blade should be imperceptible to the "fingernail test"-an approximate microfinish of 8 or smoother. Blades with tip angles of 45 deg and sharper require even smoother surface textures.
