Diamond cutting tools

At the EMO trade fair, HORN's proven DA32 milling system will be on show with diamond-tipped inserts for the first time. This feature allows the tools to achieve outstanding results during shoulder milling, face milling, plunge milling and circular milling.

The highly positive geometry of the inserts ensures a particularly smooth cut. This keeps the stress exerted on the workpiece and the tool to a minimum. As a result, a long tool life and virtually burr-free machining are guaranteed – particularly when it comes to long-chipping materials. The wide finishing radius creates the very best standards of surface quality, even at high feed rates. The coolant supply reliably ensures targeted cooling of the cutting edges as well as safe removal of the chips away from the working zone.

Thanks to the special geometry for fibre-reinforced plastics, combined with the hardness and wear resistance of the CVD thick-film diamond cutting material, outstanding levels of performance are achieved. Tried-and-tested HORN diamond substrates guarantee that the cutting edges – produced using state-of-the-art laser technology – are able to work efficiently.

All this, combined with the exceptional rigidity of the quenched and tempered steel as well as the wear-resistant TiN coating of the various tool holders, is what really makes the benefits of the DA system come into their own. The cutter head, screwed shank milling cutter and the end mill in the DA32 system are available in cutting edge diameters from 20 mm (0.7874") to 63 mm (2.4803") and with between two and six DA32 inserts.

Diamond-tipped Supermini®- and mini tools complement the product range of Horn for bore machining. They are used for turning out, copying and grooving of aluminium, sintered tungsten carbide, ceramics or plastics. They also receive for non-ferrous materials used, which either highly abrasive substances due to their Silicon content or tend to span problems and building cutting education. The chip geometry developed for this purpose solves almost all process problems which can be caused by uncontrolled confused chips.

Super Mini tools with CVD-D or PCD-cutting edges are ex stock and, depending on the range of applications in three variants of geometry from bore diameter 1.5 mm. H0 geometry is used with a cutting angle of 0 degrees the machining of hard brittle materials such as hard metals, presintered ceramic materials, graphite, as well as short spanendem brass. The applications of H5 geometry, with 5 degree rake angle, are soft and abrasive materials. These include aluminium alloy with high silicon content and fibre-reinforced and other plastics with abrasive ingredients. Diamond as cutting material is successfully used without chip problems with precious and non-ferrous metals such as Platinum, Iridium, gold, tantalum, titanium, and sinter metals such as tungsten copper. The geometry of the HF is for cutting non-ferrous metals, like all aluminum alloys, application. This includes also copper with its alloys such as bronze, unleaded and lead poor and thus long-chipping brass. The geometry is used because of controlled chip fraction for the effective prevention of process problems due to confused chips.

With CVD-D - or PCD-tipped Super Mini and mini Horn program impresses with its unique features in the market segment of diamond tools: active Spangeometrien with the coolant directly to the cutting edge.
