  • Offered in 3 sizes (Machine size and application determine proper size selection)
  • Can be used in any position with 1:1 ratio capability

This attachment is mounted stationary on a screw machine while its internal live spindle and the rotary broach rotate with the workpiece at a synchronized 1:1 ratio by means of a spline shaft and pick-off gear. During constant rotation with the work piece, the corners of the rotary broach are continually changing contact points on the work piece (wobbling type action) easily producing broached forms and eliminating secondary operations.
