Kamano Iron Works

Inner and Outer Dual-Use Knurling Tool

Kamano Iron Works’ knurling holder allows knurling on both the inside and the outside of workpieces. Tactile sensors measure the blade position in the same way as conventional inner and outer knurling tool holders.

A special feature of the dual-use knurling tool holder is that after attaching the cutting edge to the inner holder mount of the numerical control lathe, no adjustment is needed to the height of the cutting blade regardless of the lathe model. Additionally, the Kamano Iron Works’ holder can handle knurling up to within 50 mm of the end face.

The knurling tool is equipped with a medium-sized straight knurling wheel also capable of producing cross-hatched knurls. For cross-hatching, the blades are set in the left and a right wheel, angled in one direction for a first knurling pass. The blade angle is then changed and knurling repeated to form the cross-hatched pattern. Using two holders, both left and right blades can be attached for cross-hatching in one pass. Additionally, some manufacturers supply single knurling wheels designed for cross-hatched knurling.
