Hoffman group announced full slot milling in steel

The new GARANT MasterSteel SlotMachine from the Hoffmann Group is a solid carbide roughing end mill which achieves high feed rates when slot milling from solid in steel. The innovative knuckle form profile produces extremely compact swarf. Therefore, the Hoffmann Group was able to construct the milling cutter with five cutting edges. As a result, at a constant feed rate per tooth the new five-edge end mill achieves 25 percent higher process efficiency than a classic four-edge end mill. Thanks to the innovative knuckle form profile, the cutting pressure is lower and higher feed rates can be obtained with a constant load. Due to the compact chips and the lower cutting forces, the new GARANT MasterSteel SlotMachine high-performance end mill is particularly suitable both for milling deep slots from solid and also for machining delicate components.

Based on its unusual geometry, the new GARANT MasterSteel SlotMachine solid carbide end mill produces chips that are very short, very fine and particularly tightly rolled. These are easily cleared by the flat chip-breaker recesses. The directional chip discharge increases the process reliability, the extremely sturdy core diameter the tool stability.

The GARANT MasterSteel SlotMachine permits plunge angles up to ten degrees. The cutting edge design includes honing to minimise the risk of break-aways. The ultra-fine grain substrate greatly increases the resistance to breakage; whilst the enhanced coating also optimises the wear characteristics and reduces the rate of heat input. The unequal spacing ensures a smooth cutting action.
The new GARANT MasterSteel SlotMachine solid carbide end mill extends the GARANT MasterSteel product range, which currently includes the existing classic four-edge end mills and also the GARANT MasterSteel PickPocket universal end mill plus two solid carbide drills. With these the Hoffmann Group offers state-of-the-art high-performance tools for every application.

The GARANT MasterSteel SlotMachine achieves a feed rate per tooth up to 0.1 millimetre at a cutting depths up to twice the tool diameter (2xD). It is available with cutter diameters from 4 to 20 millimetres and can be ordered immediately both from the Hoffmann Group eShop www.hoffmann-group.com and the usual sales channels.
