Main cause for double tracking while knurling

Main cause for double tracking while knurling:

Double Tracking

Means that the knurling wheels are not tracking properly. In this situation, the wheels will create a different pattern than what the design was originally made for.

There are two main causes of this scenario:

  • The knurl wheel isn’t set deep enough into the workpiece. We recommend increasing the depth. The knurl depth should always equal 35 percent of the knurl pitch.
  • The circumference of the work piece blank is not a multiple of the knurl pitch. To correct this, you must change the before-knurl diameter of the part or select a knurl wheel with a different pitch.
