Abrasive-belt conversion wheel for cylindrical grinders

摘要

A conversion grinding wheel frame for an abrasive-belt to secure thereto for replacing a conventional stone grinding wheel used on a cylindrical roll grinding machine. The abrasive-belt conversion wheel is secured to a spindle of the grinding machine by a wheel clamping assembly. The abrasive-belt conversion wheel frame having an engagement working surface and a mounting surface with both surfaces having apertures therethrough traversing from a chamber within the abrasive-belt conversion grinding wheel frame. Fluid under pressure in the chamber escapes through the apertures to the working surface and mounting surface. The pressure of the gas expands the abrasive-belt while being mounted onto the abrasive-belt conversion grinding wheel frame. The mounting surface is diametrically tapered in relation to the working surface to afford initial engagement of the abrasive-belt which further assists mounting the abrasive-belt onto the working surface.
