BENZ Inc. To Feature Linear Broaching Systems and Solidfix® Tool Changing System
At IMTS 2014, German tooling systems expert BENZ, is displaying 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. Additionally, the company will present its innovative Solidfix® Modular Tool Changing System.
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 both the LinA radial and axial models in long and short stroke versions. The LinA makes manufacturing I.D. and O.D. 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.
Also on display at IMTS 2014 Is the innovative BENZ Solidfix® Modular Tool Changing System. The proprietary BENZ Solidfix® enables users to change tools quickly using adapters that hold a variety of tools instead of requiring a labor-intensive manual tool change or adding an expensive automatic tool changer. The patented BENZ Solidfix® modular quick-change system lets the user preset tools for precise, repeatable cuts and change tools in 10 – 20 seconds. It requires no special tools, can be operated with one hand, incorporates both a 180-degree clamp lock and ejection features, and contains no screws to lose.
Instead of traveling to a tool changer rack, the spindle can be programmed to move to a home position where the operator can quickly change tools and resume the routine. It helps reduce set-up time by 90% and enables users to produce additional parts every day. Its rigid, compact, balanced design also provides large multi-surface contact with high-torque and high-speed performance.
