These holders are designed to fit small to medium size CNC or manual machines. Compact Straddle holders are supplied as right-hand style, but may be reassembled as left-hand style. Right hand and left hand knurls can be used together to produce a diamond pattern. They also may be traversed to produce a long knurl pattern (beveled knurls are recommended when traversing). Straddle knurling produces much less side pressure than bump knurling. This reduces pressure on your machine and allows knurling longer parts or smaller diameter parts. Carbide pins and hex wrench are included. Knurls are not included.

Setup Procedure: Adjust the two screws on the top of the holder until the knurls just contact the work, then retract. Adjust the screw closest to the knurl a small amount tighter. Make a test roll. If the knurl pattern is too shallow, adjust again.

These holders are designed to fit medium to large size CNC or manual machines, and to roll more difficult jobs.  They are supplied as right-hand style, but may be reassembled as left hand style.  Use RH and LH knurls to produce a diamond pattern and traverse to produce long knurl patterns (beveled knurls are recommended when traversing).  Carbide pins and hex wrench are included.  Knurls are not included.

 

Setup Procedure:    Adjust the two nuts on the eyebolt until the knurls just contact the work.  Adjust slightly smaller and make a test roll.  If the knurl pattern is too shallow, adjust again.  Both nuts should be tight when adjustment is finished.
