Efficient Broaching Technology for Keyways, Involute & Straight Sided Splines
The patented elmass® Technology is based on 4 key components:
Guided single tooth broaching tools with a life cutting tip are designed to broach internal keyways and splines of exceptional quality in through holes and blind holes. The tools are self-centering and force the cutting tip to be at 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 an accurate depth over the entire length of the cut. It is ideal to broach very long keyways or splines in small bore sizes.
A range of tool bars for different applications makes the system very versatile. This includes tool bars for through bores, blind bores and mass production.
The elmass® push broaches can be used in elmass® Vertical Broaching Machines as well as in any machine that makes a linear movement (e.g. pedestal drill, lathe, slotting machine, shaper).
Defined cutter geometry of the single tooth cutter offers an unrestricted design of shapes. This makes the elmass® Broaching Tools ideal to cut internal keyways, involute or straight sided splines, hexagons as well as many other shapes.
The unique shape of the cutters enables them to be re-sharpened many times without losing their shape or tolerance.
Purpose formulated cutting oil lubricates the guide bush and cutter during the broaching process, protecting the cutter from overheating. It also acts as a rust inhibitor for a reasonably long time.
Vertical Broaching Machines designed to operate the elmass® push broaches in the most effective way. The NC controlled broaching machines are offered with a wide range of options. This makes them ideal for the mass production of keyways and splines and very flexible for jobbing applications.
