Abstract
A grinding apparatus includes an upright casing with a plurality of horizontal mounting frames and a worm journalled between a top and bottom of the upright casing. Several grinding devices are respectively mounted on each of the mounting frames and can perform different grinding operations. Each of the grinding devices is connected to the worm via transmission devices. Axial rotation of the worm correspondingly moves the grinding devices in order to complement with a radius of curvature of the curved plate that is fed to the apparatus.
