materials & tools Milling without interruption No more height adjustment with varying panel thicknesses – with the Fibonacci jointing cutter from LEUCO. Its especially effective arrangement of the cutting edges prevents overcuts between the rows of teeth. This allows the cutter to continue working regardless of the material thickness. In addition, there is the long edge life, clean results and electricity savings of up to 15 %… The DIAREX jointing cutter is a safe bet for throughfeed sizing. The tool has proven itself to be an all-rounder. It masters a wide variety of materials, even challenging ones. In addition, the bionic geometry of the cutting edges patented by LEUCO ensures an exceptional level of cutter performance. Permanent setting Thanks to the unique arrangement of the cutting edges, modeled on nature itself, the Fibonacci DIAREX cutter does not produce any overcuts from one row of teeth to the next. This allows the user to continue production regardless of the material thickness – without having to readjust the height setting. This is an advantage over conventional jointing cutters, which have to be readjusted and always have an overcut area. Milling work carried with conventional cutters can result in reduced quality of the material’s top layer. Perfect surfaces The overcut-free arrangement of cutting edges ensures better cutting quality, eliminates the need to adjust the height of the tool and increases tool life. The special arrangement of the cutting edges provides a better cutting pattern. The high, 48 ° shear angle of the DIAREX jointing cutter’s cutting edges guarantees chip-free edges and surfaces. This all-rounder can handle a variety of materials, including sensitive and abrasive ones. Reduced vibration of the material Thanks to their bionic arrangement, the cutting edges enter the workpiece with maximum uniformity, which significantly changes the amount of vibration excitation. In turn, excitation of vibration during milling is minimized and unwanted vibrations are prevented. This also results in a smoother tool operation, which reduces the load on the motor, thus protecting the machine and reducing energy consumption – by up to 15 % in the case of the DIAREX jointing cutter. Low-noise design The unique design of the cutting edge also means that noise is generated at a lower frequency during use, which is perceived as more pleasant. further information: www.leuco.com Future-proof performance with carbide rods from Boehlerit As a European premium manufacturer, Boehlerit has always set standards in the development of highperformance carbide solutions. The company provides the material basis for maximum performance and precision, particularly in the field of rotary solid carbide tools for the most demanding applications. The company offers a wide range of carbide grades with different grain sizes. In addition to the proven ultra-fine grain grade HB30F, two ultra-fine grain grades are available: HB20UF and HB44UF. HB20UF is particularly suitable for machining composite materials and for HSC applications from 60 HRC. HB44UF is designed for rotary tools that machine hardened steels up to 62 HRC. A real highlight is the HB40T grade, which has been developed specially for roughing titanium. Titanium – known for its extreme strength and thermal stress – requires a cutting material with exceptional toughness and wear resistance. HB40T delivers exactly that – and as a bar material is perfectly suited for the production of robust shank tools. Typical fields of application: aerospace, medical technology, chemical and energy technology. XS10 – the grade for diamond-coated tools With XS10, Boehlerit has a carbide grade in its range that has been specially developed for diamond coating. Typical areas of application include precise graphite machining in mould making, the production of graphite electrodes and PCB machining in the electronics industry. However, XS10 also impresses with its tool life when machining composite materials, non-ferrous metals, aluminum alloys, cast materials or hardened steels. The XS10 grade is available from stock in diameters of 4, 5, 6, 8, 10 and 12 mm – either sintered or h6 ground. further information: www.boehlerit.com 14 no. 3, September 2025
Milling with precision and efficiency materials & tools URMA AG is expanding its range of precision tools with the MX boronite CBN face milling cutter, which has been specially developed for machining cast materials and hardened steel. Here too, URMA AG relies on its proven quick-change system, which is known for optimum handling and maximum precision. URMA AG, a Swiss company with over 60 years of expertise in the field of precision tools, has established itself as a leading expert in precision machining. Under the guiding principle “Innovation is Our Tool”, the family-owned company based in Rupperswil (Switzerland) develops and produces state-of-the-art precision tool systems. These are used worldwide in industries such as machine building, the automotive industry, the hydraulic sector, and aviation. Following the launch of the innovative “MX diamond” PCD face milling cutter, there was great demand for a face milling cutter for other materials. URMA AG fulfilled the customers’ wishes and used its many years of expertise in product development. The result is MX boronite, a modular cutting tool that offers the proven and exact RX interchangeable interface to ensure perfect axial run-out without readjustment when changing cutting edges. URMA thus relies on the same technology as the MX diamond. The cutting edges of the solid carbide cutting body are equipped with up to 10 CBN tips (cubic boron nitride) and are ideal for machining hard and abrasive metals. CBN is the second hardest material after diamond. Tools made of CBN are much more wear-resistant than other cutting materials. This not only enables greater shape and dimensional accuracy, but also the reliable machining of hard materials (steel of over 60 HRC). MX boronite belongs to the latest generation of face milling tools and guarantees lean production processes and automated production. With a feed rate of 0.05 to 0.3 mm per tooth and a cutting speed of up to 3,000 m/min, the MX boronite is ideal for mass production. Various geometries are available to meet individual requirements.
