Broaching Theory
Welcome to the world of rotary broaching, a Slater Tools exclusive, fast, and accurate method of producing internal and external polygon
forms on the end of a work piece while the machine spindle is rotating. Utilizing a free broach rotation and shear angle geometry results in
less thrust force than conventional broaching. The Rotary Broaching Toolholder is used on any CNC or manual turning, milling, drilling or
screwmachine, and can be mounted in any position on your machine.
Holder Use and Operation
In a turning or screw machine, the holder is stationary while its internal live spindle, along with the end cutting broach tool, rotates with and is driven by the workpiece rotation. While rotating
with the work spindle, the end cutting broach tool’s pressure and contact points are continually changing on the workpiece (a wobbling-type action) making broached forms easier to produce.
Support Data Sharpening of Broaches
Maintenance and trouble-shooting data are shipped with each holder order. Broach sharpening is available by Slater Tools, with same day shipping.
Broach Depth
The recommendedmaximumbroach depth is 1.5 x smallest dimension of form. When a broach depth exceeds the recommendedmaximum, Slater Tools offers an attachment for multi-spindle
machines. This attachment is synchronized with the spindle via. a splined shaft, driven by pick off gears, and mounts directly to the main tool endslide of a screwmachine.
Broach Toolholders
Slater Tools offers various holder sizes, available with straight and morse taper shanks.
Broach Blanks
All internal blanks have centers provided. External and internal blanks are hardened and ground. A design and manufacturing guide is sent with each Broach
Blank order.
