Agreement to Supply Kennametal’s breakthrough KM4X spindle connection

Kennametal and Sumitomo Electric have signed a licensing agreement under which Sumitomo Electric will provide and support Kennametal’s new and advanced KM4X spindle connection solution to Sumitomo Electric customers globally. Sumitomo Electric, a leading global supplier of electric wire, optical fibers and cutting tool products, sees significant benefit for its manufacturing customers.

By combining high clamping force and optimized interference levels, KM4X™ by Kennametal provides a robust connection, extremely high stiffness, and bending load capacity for greatly improved performance in machining high-strength alloys and other materials.

The continuing development of high-strength, lightweight materials such as titanium alloys, Inconel, and new aluminium alloys are eagerly sought by manufacturers in many industries, including aerospace and defence, energy, and transportation. These new materials present significant machining challenges in themselves. Add the competitive pressures in these global industries, and finding advanced manufacturing solutions becomes a top priority.

The limits of machines
“In most cases, the tool-spindle connection determines how much material can be removed on a given operation,” says Doug Ewald, director, global product management, tooling systems at Kennametal. “This is because this interface must withstand high loads and yet maintain its rigidity. With the ongoing advances in cutting tools and machining centers, a spindle connection that makes the best utilization of available power possible is an important consideration to investigate early in production planning.” “This is a full-system partnership between companies,” says John Jacko, vice president and chief marketing officer at Kennametal. “With the KM4X spindle connection and Sumitomo Electric’s innovative technology, there is no reason why companies should hold back investigating high-torque, high-speed machining capabilities for both existing and new equipment. This means achieving the maximum potential of your machine tools.”
