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.

“Today’s high-temp alloys were engineered to hold up under some of the worst conditions on the planet,” explained v.p. - Operations Matt Osburn. “When you’re machining, those same high-strength properties become barriers to productivity. They can chew through conventional cutting tools in no time.”

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.

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.

“With increased demand for high-temp alloys in the aerospace and energy industries, Inconex M8 Series tools will fill a real need for longer tool life,” according to IMCO sales manager Tim Elfreich. “It’s a big step ahead.”

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 chip-creating design was explained by IMCO’s application support team leader Steve Avers. “Each cutting edge is specially shaped to reduce edge-wearing stress in the cutting zone. An added benefit of the new design is much smaller chips that can be easily flushed from the work zone.”

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.

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.

Inconex M8 Series tools are designed with high-strength properties and a special “chip-creating” design to break through those barriers, and keep cutting. These tools feature a carbide core with 20% higher transverse rupture strength and six flutes with optimized rake and relief angles for maximum cutting edge engagement. Advanced AlCrNX coating protects the tools’ specially engineered cutting edges from the intense heat generated in the cutting zone.

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.

Aston Martin’s plan to continually improve its supply chain sustainability has been boosted by £6m of UK government funding for a project supporting the development of lightweight, sustainable aluminium castings for future Aston Martin vehicles.

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 new Inconex line is a real breakthrough in productivity for machining in Inconel, Hastalloy, Waspalloy, and similar high-temp alloys,” according to IMCO president Perry Osburn.

IMCO Carbide Tool is introducing a new high-performance end mill designed specifically to overcome the challenges of machining in high-temp alloys. Following extensive product testing versus an array of competing product designs, as well as against IMCO’s Omega-6 series end mills, the cutting tool developer is claiming its new Inconex M8 series end mills will last up to three times longer than the competitor’s best designs, and twice as long as its own Omega-6 products.

In doing so it has extended its comprehensive range of turning inserts. The grade incorporates the company's state-of-the-art coating technology that provides outstanding wear resistance, as well as a product that improves productivity and usability.
