BENZ Inc. has announced that it will present its LinTec family of broaching tools during Houstex 2015, February 24–26, at the George R. Brown Convention Center in Houston, TX. The company will demonstrate several new LinTec broaching tools, including the LinA Axial and Radial Broach, the LinA XL Radial Broach, the LinS Axial Broach, the LinA Haas Axial, and the LinA EMAG Axial at Booth #454 during the show.

Both the BENZ LinA and LinS broaching tools perform I.D. and O.D. broaching with the one tool. I.D. and O.D. keyways, splines, torx and hex shapes can all be machined with the same tool. Use of the LinA and LinS broaching tools also reduces cycle time and increases machine life by eliminating wear on guideways and abuse on spindle bearings.

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 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 the LinA radial and axial models, available in short, standard, long and XL stroke versions.

The BENZ LinA Broach for BMT and VDI applications is available in six different models engineered for specific applications. The LinA Radial FSS has a short .669” stroke, higher operating speed, greater stability, improved surface quality and can broach a .375” x .187” x .699” keyway in 5 to 7 seconds. The LinA FS Radial has a 1.259” stroke and can broach a .375” x .187” x 1.259” keyway in 6 to 8 seconds.  The LinA FSL Radial has a 2.007” stroke and can broach a .375” x .187” x 2.007” keyway in 7 to 9 seconds. The LinA XL is designed for large turning applications and large diameter parts, with a larger 3.937” working stroke and groove width up to .7874”.  Driven by an auxiliary motor, the LinA XL is a special broach designed for non-live tool lathe applications. 

The BENZ LinA Axial Broach is available in two different models and three different lengths. The LinA FSS, FS & FSL models for Haas Axial lathe applications have strokes of .669”, 1.259” & 2.007”.  The LinA Axial EMAG is designed specifically for the EMAG VL 3 lathe application.  

The BENZ LinS broaching tool system is a one-of-a-kind system that 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 the torque arm eliminates oscillating spindle conditions which will cause the broach insert to chip. 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 wood, plastics, composites and metalworking industries. The company manufactures tooling in Germany and offers sales and support for North America through its subsidiary, BENZ Inc., from its North Carolina headquarters.
