Knurled holders for machine tools
Knurling-head
This three wheeled form knurling tool performs knurlings on small diameter workpieces. Three knurl jaws are moved by a synchronizing ring that allows an easy adjustment to the workpiece´s diameter. The coupling between the shank and the head has an auto adjusting system to compensate differences between the turret and the chuck of the machine.
To apply for: Face-knurling for axial feedAxial: AA, GE 30°, GE 45°
Machinse types: Conventional, CNC, multi-spindle, sliding head and Swiss type lathes.
Knurl holder “Conical”
This form knurling holder enables conical knurlings on right- and left-handed lathes especially in DIN-72783. The modular system allows the use of several different shanks keeping the same components. A threaded spindle enables easy adjustment to the workpiece´s diameter and an auto-centering system compensates a possible disalignment between the turret and the machine axis.
Mechanical stress is stood by the holder and not transmitted to the bearings of the machine. Even the bending risk in the workpiece is eliminated as each knurl’s pressure compensates one with each other.
Axial: KAA, KBL 30°, KGE 45°
Machines types: Manual, automatic, Swiss type, multi-spindle and CNC Lathes
Internal holder “Bore”
Internal Holders are intended to be used boring bar style (off center). Each of them has flats on diameter of shank to allow mounting in tool post. Maximum depth that can be knurled will vary with toughness of material to be knurled.

Shank conical knurl dies with TIN coating
knurling holder “Fixed” and “Adjustable”
The fixed and also the adjustable face-knurling holder are available in a standard or heavy duty version. The buildup of the fixed and the adjustable holder is the same, the adjustable holder allows to double the knurl up to a diameter of 64 mm. When knurling on these larger diameter the tip of the die is not 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.
