“VEGA” Porous Vitrified Bond Wheel for Wafers Finishing Grinding

“VEGA” Porous Vitrified Bond Wheel for Wafers Finishing Grinding

Higher surface roughness realized by intermediate processing and final processing of silicon and SiC wafers
■Higher surface roughness is realized by the combination of ultra-fine diamond abrasive grains and vitrified bonds of large and fine porous combination structure.
■Spontaneous blade generation is realized and cutting quality is maintained by bonds that can make ultrafine shredding.
■Stable high-quality surface and low processing cost can be realized.

“DEX” diamond wheels for forming difficult-to-cut materials

“DEX” diamond wheels for forming difficult-to-cut materials

These wheels are designed for high shape precision forming of, for example, motor cores. Wheels of the most appropriate specifications are available for not only magnetic materials such as neodymium-iron, but also for ferrites, ceramics and glass.

“Lenelas” diamond high-elasticity wheel for finishing

“Lenelas” diamond high-elasticity wheel for finishing

This wheel has high abrasion resistance because it uses a high-elasticity resin bond made with a special bonding agent. It realizes surface roughness of the same level as final lapping or polishing in a short period of time. By varying the bond content, it can be used to process different materials such as glass, metal, and ceramics. There are two types of bonds available: "RN" bond for better grinding performance and "RP" bond for better surface roughness.
