Sumitomo Electric Industries, Ltd. (head office: Chuo-ku, Osaka, President: Osamu Inoue, hereafter "our company") has developed and launched the high-efficiency, high-rigidity radius cutter SEC-Wave Radius Mill RSE Type for sale as of November 2021.

The turbine blades in aircraft and electrical generators use stainless steel as well as exotic alloys such as nickel-based heat-resistant alloys and titanium alloys. In machining turbine blades, the volume to be machined is large and from the perspective of machining efficiency, there is an increasing need for higher cutting speeds and feedrates.

In response to these needs, our company has developed the SEC-Wave Radius Mill RSE Type. The SEC-Wave Radius Mill RSE Type was designed to maximise the rigidity of the insert seat face on which the insert is located, exhibiting excellent durability even in high-load machining. In addition, the use of the newly developed ACS2500/ACS3000 insert grades (for exotic alloy machining) realises excellent stability and longer tool life. Apart from the high-precision 4-cornered ground type inserts, the lineup also includes highly economical M Class* 8-cornered inserts; both insert types can be used with the same cutter body depending on the application.

*M Class
Insert tolerance. Tolerances of corner height (±0.08mm to ±0.2mm), thickness (±0.13mm), and inscribed circle (±0.05 to ±0.15mm).
