RVG™ Diamond Abrasives

 

Resin Bond Diamonds are highly cost-effective abrasives that significantly increase the grinding wheel’s productivity and workpiece quality, enabling toolmakers to develop consistent high-performance tools that provide exceptional workpiece dimensional accuracy and surface integrity while minimizing total cost per part.

 

Longer-Lasting Grinding Wheels

 

One of the most significant cost factors in a grinding operation is the relationship between wheel performance and the costs incurred to attain optimal performance capabilities. RVG diamonds help enhance the material removal rate while decreasing the abrasive concentration on the "cutting zone," leading to slower grinding rates and longer cycles when grinding challenging materials. Wheel manufacturers can count on their wheels, offering tool users a predictable grinding output, leading to faster turnaround times and higher productivity.

 

Deliver Superior Surface Integrity

 

With proprietary processes for producing each RVG abrasive grade, toolmakers achieve a more robust edge finish for their workpieces. Tool users can count on utilizing the resin and vitrified grinding wheels to produce cleaner and faster cuts while minimizing scrap waste.

 

 

 

Hyperion offers several different resin and vitrified bond grinding diamond abrasives, from highly friable to extremely tough diamonds. Each product specifically focuses on providing exceptional bond grinding performance for non-ferrous material tools.
