Latest Patents

John S Sexton holds a patent for a semi-permanent peripheral grinding wheel. This innovative wheel comprises ultrahard abrasives such as diamond or cubic boron nitride, designed to overcome the serious problems caused by 'chatter'. The wheel features a hub that mounts the ultrahard abrasive, which is resiliently depressible radially inwardly of the wheel. It is engineered to have a radial static stiffness of no more than 1.5 × 10^6 N/m per mm of wheel width and a first radial natural frequency of at least 500 Hertz. The resiliency of the wheel may be enhanced by rubber pads between the abrasive and the hub or by using a hub made of resiliently deformable metal, such as 'RETIMET' sponge-like metal.
