German tooling systems expert BENZ Inc. is now offering two broaching systemsLinTec Broaching Tools that perform rotary and linear broaching for the machine tool industry. The new 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.

“Both the BENZ LinA and LinS broaching tools are innovative in that they enable machine shops to perform linear I.D. & O.D. broaching with the one tool,” explained John Roasa, National Sales Manager of BENZ Inc.’s Metal Division. “ID and OD keyways, splines, torx and hex shapes can all be machined with the same tool. Use of the LinA and LinS broaching tools reduce cycle time and increase machine life by eliminating wear on guideways and abuse on spindle bearings.”

The new 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 1000 rpm/1000 strokes per minute. It utilizes an integrated feature that lifts the tool .006” off the material on the return stroke for a better surface finish and tool life. A typical 3/8” x .187” x 1.250” keyway would take almost two minutes to cut on a lathe. The LinA can machine the same feature in steel in 6 – 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 is one-of-a-kind and 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.

BENZ Inc. is the technological leader for the production of innovative machining heads for the metalworking industry. The company manufactures tooling systems in Germany and offers sales and support for the United States and Canada through its subsidiary, BENZ Inc., from its Charlotte, NC headquarters.
