ADJUSTABLE END ROLLING HOLDERS
FOR SCREW MACHINES AND AUTOMATICS

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.
 

FIXED END ROLLING HOLDERS
FOR MANUAL & CNC LATHES



This End Rolling tool holder is the same as the adjustable system shown above but it is a single piece square shank unit with the die remaining in a fixed position. Ideal for use in manual & CNC lathes where adjustment is not needed.

END ROLLING OVER A STUB

CORRECT - INDIVIDUALLY ENGINEERED


Each job is unique and is individually engineered accordingly. The body is custom made based on part specifications with a normal delivery time of about 5-7 days. Please call (800) 433-4933 for pricing and additional information.



UNIVERSAL - USES KP & MT SERIES

In situations where the knurl band is narrow or the impression need not be exact, the universal end rolling design may be the answer. Designed to use stock knurling dies (see KP & MT), the head is adjustable to roll on different diameters.


BUMP - USES ML SERIES

The above holder, which uses ML Series, counterbored knurls, can be used on both conventional and CNC lathes.
