Featuring a Super ZX multi-layered coating, the new grades AC510U
and AC520U from Sumitomo can be used for roughing, finishing, and
medium-cut machining of super alloy materials. The Super ZX Coating
consists of thin layers of TiAlN and AlCrN, alternately stacked up to
1,000 layers. As a result, high-speed capabilities and wear resistance
are achieved.
The AC510U grade is for finish turning of exotic materials, while
the AC520U grade is for roughing and medium-cut machining applications.
The grades are available in both molded and ground insert types.
Ground tolerance inserts provide high degrees of accuracy, reducing the
amount of parts scrapped. As a result, ground inserts can be used for
high-precision applications. Sumitomo Electric Carbide Inc., IMTS Booth
