TiN 涂层和无涂层多边形不重磨式粉末冶金高速钢刀片是英国Edgar Allen Tools 公司与Bradford 大学合作发展的一种最新工具材料,这种刀片的名称叫Supersint,已在1980年国际机床展览会上展出。刀片压制成形后,按类似制造硬质合金的制造原理进行烧结。Allen 公司已解决了烧结时产生气孔的问题,并已成功地将试验结果用于生产。Edgar Allen 生产的粉末冶金高速钢刀片有四种牌号,可供车、铣、切螺纹、切断和成形加工使用。Supersint GH 和GT 刀片有TiN 涂层,供制造硬度和韧性要求较高的刀
TiN Coated and Uncoated Polycrystalline, Non-reworked Powder Metallurgy HSS Blades are the latest tool material developed by the British company Edgar Allen Tools in partnership with Bradford University. Supersint, a blade of this kind, has been manufactured at the 1980 International Machine Tool Show At the show. After the insert is press-formed, it is sintered according to a manufacturing principle similar to the production of cemented carbide. Allen Corporation has addressed the issue of porosity during sintering and has successfully used the results of the trial for production. Edgar Allen powder metallurgy high-speed steel blades are available in four grades for car, mill, thread cutting, cutting and forming. Supersint GH and GT inserts have a TiN coating for making knives requiring high hardness and toughness
