For Flute Grinding / Flute MAX
・Resin bond with heat-resistant properties reduces loss brought up by grinding heat. ・Because of heat-resistant resin bond and special filler, good grinding ability and profile consistency can be maintained even in the high heat condition such as creep feed grinding. ・Compared with conventional resin bond wheels, higher feed rate and longer dress interval are available, which improves machining efficiency and reduces costs. This resin bond wheel combines sustained sharpness and long life through the use of heat-resistant resin and a special filler uniquely formulated for this wheel. It demonstrates excellent sharpness and shape retention in creep feed grinding of flute on various tools such as endmills, drills, and reamer. ■Features Demonstrates High Performance in High-Load Grinding Using Water-Soluble Grinding Fluid

Demonstrates High Performance in Heavy Grinding RESIACE is an ultra-heat-resistantresin bond wheel that maximizes the characteristics of the highest heat-resistant resins used in functional materials for aerospace applications. It delivers extremely high performance in grinding, which has been thermally degraded by conventional resin bonds. ・The very high heat resistance protects the bond from becoming deteriorated due to heat under severe grinding conditions. ・Since the good sharpness lasts for a long time and the shape truing intervals are extended the grinding efficiency can be improved and cost can be reduced. ■Features
