 Fixed End Rolling Holders

The End Rolling System tool holder in its normal configuration has enough adjustment for the Die to Knurl up to a 1.25 inch diameter. The slide can be reversed and now the maximum diameter is 2.50 in. When knurling on these larger diameters the tip of the Die isn't on the center of the part, but if the knurl band on the part is narrow an acceptable impression can be made. In general if the rate of pitch change on the part is within 10% of the rate of pitch change on the Die a good straight knurl will be made. The greater the deviation, the more 'S' shaped will be the impression.

FOR BEST RESULTS THE FOLLOWING CONDITIONS SHOULD BE FOLLOWED DURING SET-UP

  1. Center the tip of the knurling die close to the center of the part. 
  2. Select the knurl die with a pitch that closely matches the pitch of the part. 
  3. If knurl is 'Double Tracking' loosen button head screws and adjust slide a small amount.
