Straddle Knurling Holders for Swiss Machines

Conventional 'bump' knurling methods are undesirable for smaller diameter parts as the forces will deflect the workpiece. To control this problem, a straddle knurl holder should be used to provide support to the workpiece while the knurling operation is performed. Low profile straddle knurling holders are adjustable to accomodate a range of part diameters.

Specifically designed for Swiss-type machines, our low profile straddle knurl holders keep interference to a minimum within the tooling layout of most machines while enabling use of adjacent tool positions to maximize tooling capacity.

These holders are ideal for machines such as Citizen, Star, Tsugami, Tornos, Hanwha as well as Ganesh turning centers.
