How do I decrease slitting dust?


There are classes available that span several days detailing best slitting practices. So, without getting into all of the details this question deserves, here are some quick tips on things you should check to decrease slitting dust:

  1. Blade sharpness. You're probably thinking this one is obvious and perhaps it is. However, it makes a lot of sense to have scheduled maintenance program in place to sharpen blades to make sure they are kept at their optimum performance.
  2. Are you shear slitting at the proper cutting depth? Typically, the greater the overlap of slitting blades, the more slitting dust will be generated.
  3. Keep top and bottom blade run-out to a minimum. You should measure the radial and axial run-out of both your top and bottom blades. Take necessary steps to decrease run-out and slitting dust will decrease.
  4. Are you slitting at the proper knife pressure? Discuss your slitting knife holders with your supplier and determine the best slitting pressure to cut your web.

Paying attention to these factors and operating your slitting process with optimum settings will decrease your slitting dust.
