The new Horn DAH high feed milling system, available from Horn Cutting Tools Ltd., Ringwood, offers enhanced productivity for roughing operations.
Horn DAH has been specially developed for roughing with high feed rates at low cutting depth. The sophisticated geometry of the triple edged inserts ensure favourable distribution of cutting forces as it has been developed to direct cutting forces in the axially. This reduces the spindle load in shear and offers significant productivity and tool life advantages.
High feed milling strategies generally allow suitable tooling to absorb very high loads using tooth feeds of up to 1 mm per tooth, comparing favourably with the relatively low cutting depths of 0.5 to 0.8 mm for conventional tools.
HORN DAH milling cutters provide significantly better values. The special cutting geometry, which combines ‘soft’ cutting with fast plunging, enables cutting depths up to 1.2 mm, providing a clear advantage over competing tools. Depending on the material, feed rates up to 3 mm per tooth can be sustained with a maximum cutting depth of 1.2 mm
The triple-edged milling inserts are currently available in the carbide grade SA4B. This offers particularly high wear resistance for milling steel and cast materials, allowing DAH tooling to combine improved productivity with extended tool life compared with alternative tooling.
Along with other Horn milling systems the holders are titanium nitride (TiN) coated which minimises chip adhesion and works in concert with the internal coolant supply to ensure optimum swarf evacuation.
The shanks are available as end mills with Weldon toolholder and as industry standard threaded connection cutter with the MD holder design already proven in the DA system.
With cutting edge diameters of 20, 25, 32 and 40 mm, the new DAH milling system expands the product range of the Horn company for tool making, mould making and general milling applications in the direction of larger diameters and higher feed rates.
