2 Advanced Technologies for Gear, Spline and Rack Manufacturing See it in action The VARDEX Gear Milling Concept Advanced milling tools with multi-flute indexable carbide grade inserts for super fast machining. Offering a competitive alternative to the traditional ob system. Tailor-made inserts and holders designed per customer application, with the exact required profile shape (evolvent, involute or any other profile) to be transferred to the component. New Clamping System New stopper technology for guaranteed radial and axial run out s are pre-assembled on the toolholder and remain intact when changing inserts Gear Milling System Advantages Super Fast Machining At least 50% less machining cycle time over other methods Carbide inserts with full profile designed for single pass machining ing Long Tool Life Tough sub-micron grade coated inserts with up to 3 cutting edges es igh Accuracy & Quality Machining No need for additional machining igh quality surface finish Economical Solution Absolute Price/Performance advantage over existing technology igh Precision Machining Gears: Up to Class 7 according to DIN 3962, or Class 11 according to ANSI Involute Splines: According to DIN 5480 or ANSI B92.1 Straight sided Splines: According to ISO Simplified Machining Easy set-up and use on standard 3.5 axis CNC milling machines 2

3 Major Applications GEAR The VARDEX Gear milling tools are suitable for machining both straight and helical teeth covering modules from mm or DP SPLINE The VARDEX Spline milling tools are suitable for machining both involute or straightsided profiles, covering modules from mm or DP 48/96-4/8. RACK The VARDEX Rack milling tools are suitable for covering modules from mm or DP Gears, Splines and Racks can be machined with either Shell Mills, End Mills or Disc Mills.
