In the rough

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 axially. Horn claims that 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 1mm per tooth, comparing favourably with the relatively low cutting depths of 0.5mm 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 1.2mm and, depending on the material, feed rates up to 3mm per tooth can be sustained with a maximum cutting depth of 1.2mm

The triple-edged milling inserts are currently available in the carbide grade SA4B which offers particularly high wear resistance for milling steel and cast materials, allowing DAH tooling to combine improved productivity with extended tool life.

Along with other Horn milling systems the holders are titanium nitride (TiN) coated which minimises chip adhesion and works in conjunction 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 cutters with the MD holder design already proven in the DA system.

With cutting edge diameters of 20mm, 25mm, 32mm and 40 mm, the new DAH milling system expands Horn's product range for toolmaking, mould making and general milling applications in the direction of larger diameters and higher feed rates.
