POWERFUL GUIDANCE AT NEW DEPTHS
Walter presents the X·treme Evo Plus drill with Krato·tec® in 8 × Dc
Premium tool manufacturer Walter is presenting its X·treme Evo Plus drill from the DC180 Supreme product family – in 8 × Dc for the first time. The drill with through coolant and four lands is distinguished by extraordinarily good guidance in the drill hole. It consequently enables high precision, even for greater drilling depths and interrupted cuts, while increasing process reliability.
The same applies to the polished flutes which optimise chip evacuation (e.g. for stainless materials), as well as the straight cutting edges which likewise offer an increased level of reliability and stability. The Krato·tec™ multi-layer coating, specially developed for drilling and reaming tools, achieves the highest cutting speeds and increases tool life by about 50% when compared to other products on the market. With the 8 × Dc version, the AlTiN layer is designed as a tip coating in Walter’s own WJ30EYgrade for the first time.
The DC180 Supreme drill can be used universally for a multitude of applications in all ISO materials from the P, M, K, N, S and H groups. In addition to the standard dimensions (dia. 3–20 mm), Walter also offers the solid carbide drill as a special tool with intermediate dimensions and as a step drill. With the Walter Xpress service, users also benefit from a reduced delivery time (max. three weeks). Due to its productivity and wear resistance, the DC180 Supreme can optimise the costs of complex ISO M and S machining operations in the long term, for example in the aviation industry or with components for the automotive industry. The Krato·tec™ coating boasts additional advantages in terms of tool life and process reliability.
NEW SPECIALIST J PROFILES FOR AEROSPACE
Walter is expanding its threading tool sizes in the standard range
Walter is expanding its existing portfolio for J profiles with extensive new dimensions for the Paradur® Ti Plus and Paradur® Ni 10 blind-hole taps, for the Prototex® TiNi Plus for through-hole threads as well as the new TC630 Supreme thread milling cutter.
Users can now obtain practically any thread size in the standard range in the profiles MJ, UNJC and UNJF. Thanks to their high load-bearing capacity, threads with the J profile are preferred in the aerospace sector (e.g. for engine components) since this involves difficult-to-machine materials such as titanium (on the “cold side” of the engine) or nickel-based alloys (on the “hot side”). The tried-and-tested Walter tool families have been specially specified for these exacting requirements, for example with appropriate coatings or helix angle geometries.
All four tools have an extremely stable design and guarantee high process reliability in difficult-to-machine materials. The Paradur® Ti Plus for titanium machining is impressive due to stable cutting edges and its highly wear-resistant, titanium-free ACN hard coating that prevents the formation of built-up edges. It also enables a very long tool edge life and excellent thread quality. Paradur® Ni 10 for nickel-based alloys is particularly suitable for both cost-effective and reliable machining of difficult materials such as Inconel 718. Prototex® TiNi Plus is ideal for the universal machining of challenging titanium and nickel alloys with one tool; whereby the newly added TC630 Supreme orbital thread milling cutters are specially designed for components made of stainless steels and high-tensile materials such as titanium or Inconel with the highest demands on process reliability. They are therefore impressive – even in unfavourable conditions – thanks to their versatility in practically any material. Overall, Walter offers its customers one of the most comprehensive ranges for J profiles.
THE FULL RANGE FOR GROOVING APPLICATIONS
Walter Tiger·tec® Gold grades WSM13G, WSM23G, WSM33G and WSM43G
With the new grades WSM13G, WSM23G, WSM33G and WSM43G, Walter is not only expanding its Tiger·tec® Gold range for grooving applications, but also making it suitable for universal use from grooving and parting off to groove turning in virtually every material.
The multi-layer Tiger·tec® Gold PVD coating of the inserts was specially developed for the main types of wear that occur when grooving. What makes them so special is the combined TiAlN and TiSiN multi-layer coating, which makes the layers very hard and resistant against both flank face wear and plastic deformation. This is complemented by a special post-treatment process which ensures smooth rake faces, less friction and improved toughness. Walter is offering the grades in four versions with different levels of hardness or toughness. The WSM33G universal grade is suitable for 80% of grooving applications in steel and stainless or heat-resistant alloys.
If the level of wear is too high, users can choose from two harder grades for ISO M, S and P materials: The WSM13G is suitable for finishing and medium machining with uninterrupted cuts. The WSM23G is suitable for stable conditions, high cutting speeds and when oil is used as the cooling lubricant. For highly heat-resistant materials, such as Inconel 718, the WSM13G achieves maximum tool life in combination with 150 bar precision cooling. If a tougher grade is needed, the WSM43G for interrupted cuts, low cutting speeds or unstable conditions is the ideal choice. Walter is offering the grades for all its grooving systems: As a single-edged SX insert with positive engagement and self-clamping system, as a four-edged MX cutting insert with tangential clamping and dowel pin location and as a double-edged DX18 with positive engagement in the insert seat (from an insert width of 1 mm). All three offer outstanding friction and wear protection characteristics, thanks to the patent-pending TiSiN/TiAlN multi-layer coating and excellent wear detection due to the gold-coloured TiSiN top layer.
