German tooling systems manufacturer, Benz Inc., is now offering two broaching systems that perform rotary and linear broaching for the machine tool industry. The Benz LinA broaching system provides linear reciprocating motion for turning centers, while the LinS system is used to perform linear broaching motion for machining center applications.

The Benz LinA broaching system changes the rotary motion of the live tool turret into a linear motion for broach and spline machining on turning centers. With the LinA in place, the programmer can position the Z axis to the start position and program a constant X feed until the broach depth has been achieved, at 1,000 rpm/1,000 strokes per minute. It utilizes an integrated feature that lifts the tool 0.006” off the material on the return stroke for a better surface finish and tool life. A typical 3/8” × 0.187” × 1.250” keyway would take almost 2 minutes to cut on a lathe. The LinA can machine the same feature in steel in 6 to 8 seconds. Benz offers both the LinA radial and axial models in long and short stroke versions. The LinA makes manufacturing ID and OD profiles extremely fast, easy and less abusive on the lathe.

The Benz LinS broaching tool system enables programmers to broach splines, torx, hex and keyways on their machining centers. The LinS provides broaching solutions without compromising either spindle or spindle-bearing integrity. By rotating the spindle at 50 rpm, the LinS provides spindle and bearing protection and eliminates oscillating spindle conditions while broaching from a variety of angles. The LinS can also be adjusted manually to provide 360-degree rotation and can be used with a fourth axis to create splines, torx and hex shapes.
