Whereas carbide suffers a significant loss of hardness at around 800°C, the hardness of CBN remains almost unchanged at temperatures up to 1,200°C. Another significant advantage is good chemical resistance, even at these high temperatures.

The ultra-hard material is capable of smooth machining even during interrupted cutting when hard turning and grooving. By extending its existing standard ranges of Supermini 105, Mini 11P, 229 and 315 systems, Horn is able to deliver the CBN tools quickly from stock.

Tooling manufacturer, Horn has introduced a new carbide insert grade, SG66, for turning components from steel that has been case hardened to 58 HRC.

The Supermini system is available in left- and right-hand versions with different corner radii. The CBN-tipped variants are for internal machining from a diameter of 2mm. Different lengths of solid carbide body are available. Tools in the Mini family can be used from an internal diameter of 6.8mm and are also available in left- and right-hand versions.

The single-edged tool type 315 is for external grooving from a width of 0.5mm. In the cutting insert system 229, the previous CBN substrate CB 50 is replaced by the higher performance substrate CB 35. Inserts are available with two different corner radii and cutting widths from 3mm to 6mm.

“The new premium series roller cone drill bit line advances our popular standard line of roller cone bits into the premium markets, bringing reliability and cost effectiveness to our customers in their more demanding applications,” says Hossam Elbadawy, Tercel CEO. “We are very proud of this industry leading seal design which extends our bearing life beyond anything else available on the market today.”

Tercel’s premium bearing roller cone bit line has precision machined bearing races that are matched to provide the optimum fit and finish for extended operations, even with parameters of higher RPM (revolutions per minute) and heavy WOB (weight on bit). The bearings are designed and machined for reliability and consistency.

CBN is the second-hardest material after diamond. Tools made from CBN wear much more slowly than other cutting materials when used appropriately. It is consequently possible to achieve higher dimensional and profile accuracy, even when machining hard materials such as steel up to 70 HRC.

As the Advanced Engineering show approaches, there are fresh announcements of cutting-edge technologies and products to be showcased at the upcoming event at the NEC in Birmingham on October 30 and 31. As a result, this year’s exhibition is shaping up to be a must-attend for engineering and manufacturing professionals, offering a glimpse into the f...

The seal system is designed to provide optimal configuration and a specially formulated extreme pressure synthetic lubricant that extends the bearing life. Specially formulated tungsten carbide hard facing is applied to all surfaces of the steel tooth cutting structure as well as on the shirttail tip and leading edge on all TCI (tungsten carbide insert) and steel tooth premium bits to provide extra protection in challenging formations. For additional security, flat top TCIs are pressed into the gauge surface of each steel tooth cone.

Horn has announced an expansion of its product portfolio to include tools tipped with cubic boron nitride (CBN) for machining difficult materials, such as superalloys and hardened steels.

Tools made from CBN wear much more slowly than other cutting materials when used appropriately. It is consequently possible to achieve higher dimensional and profile accuracy, even when machining hard materials such as steel up to 70 HRC. There are no different grades of CBN. Differentiation between tools is down to the CBN volume fraction, the fillers, grain size and the ceramic/metallic binder phase (cobalt/nickel). This results in different CBN substrates. Hard machining is usually carried out without coolant, as these cutting materials have high heat resistance and the elevated temperature within the chip formation zone has a positive effect.

In a significant move to streamline mechanical testing and enhance material insights, Airbus is collaborating with Plastometrex to support the standardisation of PIP (Profilometry-based Indentation Plastometry) – the innovative mechanical testing technique developed and commercialised by the Cambridge-based technology provider.

The NeoMill-Alu-QBig indexable insert milling cutter from Mapal stands for top performance in high-volume milling of aluminium. The tool manufacturer thus offers a very economical solution for use on high-performance machines, such as those found primarily in the aerospace industry.
