Sumitomo Electric Industries, Ltd. (Head office: Chuo-ku, Osaka, President: Osamu Inoue, hereafter "our company") has developed and launched new milling grades XCU2500 and XCK2000 for sale as of February 2021.

As milling is a process that involves intermittent contact between the tool and work material; not only will the tool require wear resistance but also the chipping resistance to withstand the impact of contact with the work material. New coated carbide grades for milling, XCU2500/XCK2000, apply the newly developed Absotech™ X coating, which combines high wear resistance and excellent fracture resistance, to realize overwhelming long tool life while contributing to reduced tool costs.

「XCU2500/XCK2000」


1. Features

■ Excellent wear and fracture resistance

XCU2500/XCK2000 apply the Absotech™ X coating, newly developed with our proprietary technology, on a tough carbide substrate. With proprietary structural control technology, Absotech™ X comprises layers of AlTiN with different aluminum content stacked at the nanometre level, displaying high hardness and outstanding wear resistance even with a high aluminum content of over 80%. In addition, the application of proprietary surface treatment technology imbues the coating with high compression stress, realising excellent fracture resistance. With at least twice the wear resistance and three times the fracture resistance of conventional materials, amazing long tool life can be realised.

■ Supports various machining operations

XCU2500 offers outstanding performance, regardless of cutting speed, on various work materials such as steel, cast iron, stainless steel, etc. XCK2000 realizes amazing long tool life in high-speed machining of cast iron.
