Broaching Tools Perform Linear I.D. and O.D. Broaching with One Tool

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.

The BENZ LinTec broaching tool lineup includes the LinA Axial and Radial Broach, the LinA XL Radial Broach, the LinA Haas Axial and the LinA EMAG Axial.

The BENZ LinA broaching tool performs I.D. and O.D. broaching with 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 broaching tool also reduces cycle time and increases machine life by eliminating wear on guideways and abuse on spindle bearings," said a company spokesperson.

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," said a company spokesperson. "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," said the spokesperson. 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" and 2.007". The LinA Axial EMAG is designed specifically for the EMAG VL 3 lathe application.
