How To Eliminate Double Tracking of your Knurling Tool

Tech Tip: Dorian Tool

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In this situation, the wheels will create a different pattern than what the design was originally made for.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:

1. 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
2. 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.

Dorian Tool Developed a “Knurling Calculator Spreadsheet” that can calculate all of the parameters to avoid double tracking. Request an electronic copy by emailing us at: sales@fltechnical.com
