Hyperion Materials and Technologies manufactures the very tough CSG and RB series diamonds. These man-made or synthetic diamonds are available as uncoated or coated. Additional information is provided below:
Nickel-based alloy coating [coating level 55 wt %]
This very tough diamond reduces wheel loading and minimizes workpiece burn when grinding tungsten carbide/steel combinations. Due to its toughness and impact resistance, CSG-II diamond is highly recommended for heavy duty grinding and applications with interrupted cut.
RB-I diamond is best suited for applications where free cutting capabilities, low cutting forces, and thermal stability are required. Tungsten carbide and PCD grinding are excellent matches for this diamond.
Nickel-based alloy coating [coating level 56 wt %]
This blocky crystal form provides long tool life in applications where high material removal rates in hard-to-grind materials are a priority. Very good results are delivered in applications that sustain interrupted cuts. RB-II diamond is recommended for tungsten carbide and PCD grinding.
RB-II 30 Diamond
Nickel-based alloy coating [coating level 30 wt %]
This diamond is similar to RB-II diamond but has a lower coating level. RB-II 30 diamond provides lower grinding energy and heat and is ideal where a balance of wheel life and grinding energy is critical.
Copper-based alloy coating [coating level 50 wt %]
RB-D diamond is a blocky crystal with a copper coating applied, which provides excellent performance in dry grinding or wet polyimide, tungsten carbide, and PCD grinding.
