Norton Paradigm diamond and CBN wheels from Saint-Gobain Abrasives are designed for high-performance grinding of carbide and round-tool fluting on high speed steel to decrease cycle times and cost per part. According to the company, the bond on the wheels enables one-pass flute grinding for round tool manufacturing operations. The wheels are positioned in the “Best” tier of Norton grinding products.
The wheels are truable both online and offline, and they are wear/load resistant for better grinding on 6- to 12-percent cobalt. A high grain retention and uniform structure provide a high G ratio (ratio of material removal rate versus wheel wear), increased wheel life and a higher removal rate, the company says. The wheels are also said to offer low specific cutting energy for faster grinding with a lower power draw and less burn.
Paradigm wheels are custom-manufactured to meet end-user requirements. The wheels are available for Anca, Makino, Rollomatic, Star, Walter and various other grinding systems. Diamond wheels are available for tungsten carbide, and CBN wheels are offered for high speed steel applications.
