Having revolutionised the industry in the past with the Tiger·tec and Tiger·tec Silver coatings, the machining specialists at Walter AG in Tübingen are now making another technological advance. Walter is one of the world’s first companies to present a new technology platform: Tiger·tec Gold – with the WKP35G milling grade. Compared with the CVD aluminium oxide-coated grades currently in use, the new Tiger·tec Gold with a titanium aluminium nitride (TiAlN) coating once again boasts significantly improved properties – resulting in longer tool life, increased productivity and greater process reliability. This is partially due to the innovative, special “ultra low” coating process (ULPCVD) that Walter has used to establish tomorrow’s technology today.

The new TiAlN coating from Walter is their response to growing demands. The Walter developers have been using Tiger·tec Gold for some time now in special applications – and to great effect. They recorded markedly improved properties compared with other coatings: Considerably higher wear resistance on the flank faces, reduced formation of hairline cracks and greater resistance to plastic deformation. Numerous practical tests on steel and cast iron materials demonstrated considerably longer tool life – often by up to 200 %. In addition, the gold-coloured top layer also facilitates wear detection. Walter will be presenting this new technology to the public for the very first time at the AMB in Stuttgart

Stability is everything when it comes to porcupine cutters, a characteristic feature of the Walter BLAXX range.

Walter is now extending its high-end range: As are its fellow cutters for face milling and shoulder milling, the new Walter BLAXX F5038 porcupine cutter is also characterised by an extremely solid and therefore stable tool body.

In conjunction with the tangential, quadruple edge, system indexable inserts made of Tiger·tec® Silver cutting tool materials, the user thereby achieves top values in process reliability and cost efficiency. In comparison to conventional tool solutions of this type, machining times are reduced by up to 30 percent. What’s more, the accurately arranged, precision indexable inserts produce flawless and step-free shoulders that, to the greatest possible extent, make re-machining superfluous.
