At an online press conference held at Trumpf’s in-house INTECH exhibition earlier this year, top managers discussed the impact of artificial intelligence (AI) both on the products the company supplies to its customers and on its own manufacturing processes.

The new line of inserts deliver a variety of performance and benefits through constant refinement and R&D work. This has created a new sintered substrate containing both micro and medium grain CBN particles, but with an ultra micro-particle binder.

“One of his most important legacies, however, is the outstanding team he has built at Element Six, which has a wealth of knowledge, expertise and passion, as well as a clear vision of where the key opportunities for the business lie in the future,” Cleaver continued. “Synthetic diamonds have the potential to transform the world of technology, and Walter’s successor will work closely with the leadership team to ensure Element Six remains at the forefront of innovation in the advanced material solutions sector.”

In today's manufacturing landscape, sustainability has emerged as a pivotal focus. As industries face increasing pressure to reduce their environmental impact, the integration of sustainable practices presents both challenges and opportunities.

This new binding technology in the substrate offers high heat resistance and prevents sudden fracture by eliminating the potential for linear crack development. With the cutting forces being dispersed radially by the new binder formula, BC8220 excels when machining extremely hard steels. Additionally, the new substrate enables a wider range of applications, provides greater chipping resistance and wears less.

Above this layer is an additional TiAlN ceramic layer that provides excellent chipping and crater wear resistance. Together with a gold coloured, TiN top layer for easy identification of used edges, BC8220 achieves high performance and reliability over a wide range of hardened steel machining applications.

The latest technology has also been applied to a specially developed, multi-layer ceramic PVD coating that the BC8220 grade utilises. This all new multi-layer coating includes a TiAlN bottom layer that greatly improves adhesion between the base layer and the CBN surface and provides exceptional peeling resistance.

For the effective light-to-medium continuous and interrupted turning of high hardened steels, Mitsubishi Materials has developed a new and innovative coated PCBN insert grade, BC8220.

Over the past decade, Element Six has successfully navigated a wide range of challenges and opportunities, fulfilling many strategic developments, including broadening its oil & gas product offering to a wider customer pool, accelerating the market penetration of tungsten carbide and synthetic diamond solutions, and the expansion of CVD production capabilities to satisfy growing markets in semiconductors, defence and high-power laser applications.

At depths of cut up to 0.8mm and at cutting speeds up to 250m/minute means a wide range of applications can be covered by a single grade. This brings a simplification of choice for the production programming and reduces inventory costs.

The initial launch of BC8220 will include an extensive range of negative geometries with multiple cutting edges in CNGA, CNGM, DNGA, DNGM, SNGA, TNGA, VNGA and WNGA types, plus positive CCGT, CCGW DCGT DCGW TPGB CPGB VBGW VCGW geometries.

Element Six (E6), part of the De Beers Group, has announced that Walter Huehn will stand down as Chief Executive Office, effective January 31, 2023. The process to recruit Huehn’s successor is reportedly underway.

Two chipbreakers, BF and BM complete the series. The BM type is designed for easy and effective removal of carburised layers at depths of cut up to 0.8mm. The BF type is now available as a standard item and can be combined with a wiper geometry for producing first class surface finishes.
