Abstract:
The invention features a self-contained, portable apparatus for performing precision grinding operations on metal disks of up to, e.g., 54 inches in diameter. The apparatus can be attached to the surface of the disk to be refinished and is leveled using special precision leveling adjusters. During operation, the adjusters are turned in precision increments to set the depth of cut. The grinder is then rotated on an arm about the center of the disk, by the use of a hydraulically driven speed reducer, rotor, bearing assembly. In a further aspect, the invention includes a dressing assembly for performing dressing-truing on a vitreous wheel when the wheel is in grinding position. The in position dressing assembly dresses a grinding wheel at up to 0.00125-inch increments.
