BENZ Inc. will present its LinTec family of broaching tools. 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 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. According to the company, 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 1,000 RPM/1,000 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. According to BENZ, 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 - 7 seconds. The LinA FS Radial has a 1.259" stroke and can broach a .375" x .187" x 1.259" keyway in 6 - 8 seconds. The LinA FSL Radial has a 2.007" stroke and can broach a .375" x .187" x 2.007" keyway in 7 - 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 and FSL models for Haas Axial lathe applications have strokes of .669", 1.259" and 2.007". The LinA Axial EMAG is designed specifically for the EMAG VL 3 lathe application.
The BENZ LinS broaching tool system is, according to the company, 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," said a company spokesperson. "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° rotation and can be used with a fourth axis to create splines, torx and hex shapes.
