Benz will display four new tooling systems: its LinA and LinS broaching tools, C-axis angle head and the Mini Flex angle head.

Both the LinA and LinS broaching tools perform ID and OD broaching for keyways, splines, torx and hex shapes. The tools are said to reduce cycle time and increase machine tool life by eliminating wear and abuse on the guideways and spindle bearings.

The LinA system changes the live tool turret's rotary motion into a linear motion for broach and spline machining by lifting the tool off the material 0.006" on the return stroke for a polished surface finish and increased tool life. The user positions the Z axis to the start position and programs a constant X feed until broach depth is achieved at 1,000 rpm (1,000 strokes per minute). Its radial and axial models are available in both long- and short-stroke versions.

The LinS system enables broaching on machining centers without compromising spindle or spindle-bearing integrity, the company says. The torque arm is said to eliminate oscillating spindle conditions that can cause broach inserts to chip, and rotating the spindle at 50 rpm provides spndle and bearing protection during broaching operations. The LinS system can be adjusted to provide 360 degrees of rotation and can be used with a fourth axis to create splines, torx and hex shapes.

The company will also exhibit its C-axis angle head which can be automatically rotated to predetermined positions while mounted in the machine. Also on display will be Benz’s compact Mini Flex angle head for drill/tap machine tools, available in 90-degree or adjustable angle head versions.
