Cutting
Milling

Regardless of whether it is a roughing application or face milling on low-performance machines: Boehlerit offers four different face milling systems that cover the high demands of our customers through the optimal pairing of design, cutting materials and costs per cutting edge. For high machining volumes, Boehlerit also offers the option of choosing from one of two available high-feed milling systems in order to achieve high economic efficiency.

A multitude of machining possibilities requires a multitude of solutions. Based on many years of experience in the milling sector, Boehlerit has developed seven edge milling systems to date in order to be able to offer the optimal solution for each application. Thanks to the multifunctional nature of some milling systems, the range of applications can be increased, thus reducing costs, by simply changing the indexable insert.

With the DELTAtec 90P Feed, the company already has a versatile milling system in its portfolio and is now adding smaller-​format tools. The BALLtec copying tool was specifically developed for finishing - resulting in two new geometries, one for pre-finishing (N geometry with neutral rake angle), the other for fine finishing (F geometry with positive rake angle). The hardness and toughness behaviour of the newly developed grade BCH13M offers special properties in machining. This also brings with it a new geometry with convex helical cutting edges, and fits into the BALLtec programme with the designation FHF2. These tools may also be combined with the Vidat vibration-​dampening extension system by Boehlerit technology partner Bilz. Solid carbide extensions by Boehlerit may also be used. The BALLtec carrier tools are available in a high-​precision steel design and in a version with a solid carbide shaft.

The RHOMBICtec milling system is also suitable for finishing, but within a larger diameter (16 to 25 mm), and is suitable in particular for 90-​degree, plane surface, and contour finishing in die and mould making applications.The ISO 00P programme for roughing applications is also a complete novelty. The programme is extensive and contains a multitude of round indexable inserts for the machining of a wide range of steels as well as cast materials.When developing these three tooling systems, the Kapfenberg-​based carbide and tool experts focused on performance as the key element.

And the new cutting grades can certainly hold their own in this respect, for instance the extremely hard, ultra-​fine grain grade BCH03M with a cobalt content of just 3 percent, which, in combination with the RHOMBICtec system, is ideal for the finishing of even the hardest materials (up to 65 HRC). This grade is also available for the ISO 00P. Two grades that were specially developed for die and mould making complete the product range: BCH05M is CVD-​coated and, in combination with ISO 00P, particularly suited for high-​feed applications thanks to its stable cutting edge. The universal BCH10M grade is also available for BALLtec, RHOMBICtec and ISO 00P.

Solid carbide milling programme sets new standards

Boehlerit now offers a full-scale solid-carbide milling programme: with innovative technology and versatility, the Austrian carbide and tool specialist raises the bar for the entire industry, all the way to the most challenging machining applications.
The solid-carbide milling portfolio compiled by the Boehlerit cutting material specialists once more focuses on quality and performance, with a carefully thought-out blanks concept on the one hand and high-grade substrates and coatings on the other. This includes PVD coating as well as solid-carbide milling cutters with diamond coating, used for the machining of materials with a high silicon content. Given this level of versatility, there are virtually no limits to possible applications. For roughing applications with large cutting depths, for instance, the programme includes soft-cutting milling tools that require only little machine capacity. These tools are available in diameters from 3 to 20 mm and stand out for their high performance and long lifespan. In addition, the Styrian material specialists also offer standard solid-carbide milling cutters with a special substrate for machining hard materials of up to 58 HRC. Hardened materials (up to 65 HRC) pose an even greater challenge for tools: with this in mind, the Boehlerit developers have also included highly wear resistant solid-carbide milling tools for tool and mould makers. The solid-carbide range also includes tools for milling softer materials such as aluminium, copper or even plastic. 
With over 1000 products, this is Boehlerit's most extensive solid carbide milling programme to date. What they have in common is high performance, resistance and tool life - the characteristics that are expected from a carbide and tool specialist. In addition, it is possible for the customer to quickly realise individual special solutions.

Aluminium milling grades BWN10M and BCN10M - A cut above

Boehlerit, Austrian development pioneer for cutting materials made from carbide, is creating a strong impulse for the aluminium sector. At the EMO in Hanover, the Kapfenberg-​based company presented two additions to its existing aluminium programme in the form of the BWN10M and the BCN10M, both of which explore new avenues in terms of grades, systems and indexable insert design. The new cutting material solutions BWN10M and BCN10M are manufactured for the premium segment, leveraging the wealth of experience held by Boehlerit and fulfilling the most stringent quality requirements. They are intended as high-​end solutions for the milling of aluminium, aluminium alloys and non-​ferrous metals.

A strong signal in the field of special machining

Absolutely new in Boehlerit's milling programme is the VARIOtec tool system. This is ideally suited for turbine blade milling and also offers carrier bodies and cutting materials that are adapted for copy machining.
