高速进给的钢件槽铣削Full slot milling in steel at a high feed rate

2016年11月2日，慕尼黑—来自霍夫曼集团的全新GARANT MasterSteel SlotMachine是一种由硬质合金金属制成的粗加工铣刀，应用于高速进给时对钢件进行槽铣削。创新关节状外形带来极为紧密的切屑。所以，霍夫曼集团能以5个切削刃口来打造该铣刀。由此，在每齿进给速度恒定的情况下，该新型5刃铣刀的加工效率比传统4刃铣刀高出25%。正因有了创新的关节状外形，所以切削压更小，在负载恒定时，进给速度更快。由于切屑紧密聚合并且切削力较低，全新GARANT MasterSteel SlotMachine高性能铣刀尤其适用于对固体物件进行深槽铣削以及精密件加工。

Munich, 2 November 2016 – 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. 

基于其独特的几何构造，全新GARANT MasterSteel SlotMachine硬质合金铣刀加工时所产生的切屑既短且细，同时也极为紧密地辗绕在一起。这些切屑能轻易通过平直的排泄槽清除。切屑的定向排放增加了加工过程的可靠性，极其稳固的内径提高了工具的稳定性。

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.

GARANT MasterSteel SlotMachine允许刀具切入刀角度最大可达10度。切削刃口的设计融合了研磨，用以将脱刀风险降至最低。超细颗粒基质大大增加了破裂抗性；同时，增强涂层提升了耐磨特性，并降低了热传导率。不均匀的间隔确保顺畅的切削过程。

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.

全新GARANT MasterSteel SlotMachine硬质合金铣刀拓宽了GARANT MasterSteel的产品系列范围，目前GARANT MasterSteel系列包含现有的传统4刃铣刀以及GARANT MasterSteel PickPocket通用型铣刀，外加2种硬质合金钻头。有了这些产品，霍夫曼集团可为任何应用领域提供高性能的先进刀具。

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. 

GARANT MasterSteel SlotMachine 每齿进给速度可达0.1毫米，切削深度可达铣刀直径2倍。 铣刀直径可选范围4至20毫米，即刻就可通过霍夫曼集团网上商城www.hoffmann-group.com和常规销售渠道订购。
