Elmass (Australia) Pty. Ltd. operates a highly specialized contract broaching workshop. We broach internal keyways, splines, hexagons and many other shapes in blind bores and through holes. We are equipped with the latest Elmass broaching technology and work with most materials used in aerospace, general engineering, food processing, medical and chemical applications. We work to ISO 9002 Quality Standards and offer a fast turnaround at competitive rates.

Our Competitive Advantage

The Elmass Technology is based on guided broaching tools and vertical broaching machines. It offers many advantages and eliminates common problems such as misalignment of the keyway as well as vibration or deflection of the cutting tool which are associated with conventional broaching and slotting methods.

Our guided broaches are self-centering and force the cutter to be in a 90 degree angle to the bore. The eccentric guide bush inhibits any deflection of the tool bar. This results in a keyway or spline, that maintains the depth over the entire length of the cut.

The precision ground tips, which have a highly defined geometrical shape, cut with zero clearance. We carry a large range of standard tools in H9, P9 and JS9 tolerances. Tools of any other shape or tolerance can be made to your requirements within a few days.

Capabilities

We are equipped to broach internal keyways and splines within the following specifications in metric or imperial standards:

• Cutter width: 2mm to 36mm
• Keyway / Spline length: max. 400mm
• Bore Diameter: 6mm to 150mm
• max. work piece height: 650mm
• max. work piece width: 800mm

We carry a wide range of standard tools to broach keyway and splines. Not frequently used shapes and sizes can be made to order within a few days.
