quality. A backing layer to the abrasive allows the Genis CF core to be reused up to three times to reduce the cost. Another interesting option for such applications is the new Noritake (Mason, OH) vitrifi ed CBN Mega-Life wheel. Also claiming a “high strength” bond and longer dressing cycles (making it “long-life”), the wheel has demon- strated impressive results in cam profi le grinding, with material removal rates up to 282 mm3

second in FC250 chilled cast iron using a 350-mm diameter wheel running at 80 m/s. In a contour grind of SCM435 (48 Rockwell), a 380-mm diameter
be open. As Senior Sales Engineer Mark Smith says “the bond bridges are almost wiry looking, leaving huge voids. I call it Swiss cheese. It’s almost like milling rather than grinding.” And Asahi can adjust the porosity for the application.

Asahi’s AeroMetal bond is so open and wiry Senior Sales Engineer Mark Smith calls it “Swiss cheese.” The metal bond can hold either diamond or CBN grains from 40 to 1000 µm.
Mega-Life wheel had a stock removal rate of 183 mm3

the wheel (traverse grinding) at a wheel speed of 120 m/s. That was a 3.5× improvement in the G-ratio versus the previous wheel.
Rough Grinding SIC Wafers with “Swiss Cheese”
Asahi Diamond America (West
Chester, OH) also has a new porous bond for better chip evacuation. As its name suggests, AeroMetal features a metal bond for excellent grit retention and wear resistance, but it’s designed to
