New Super-finishing Wheel “Keen Stone”

The Keen Stone achieves excellent cutting performance and consistent machined product quality through the fastidious pursuit of uniformity in wheel structure.
As there is very little chip deposition on the work surface, grinding volume can increase and consistent surface texture can be maintained.
In addition, Noritake is able to control the wheel structure, enabling us to provide wheels that are optimized for the grinding conditions.
