The PG-9x20DHD centerless grinder was designed to form ceramic components such as unfired carbide by plunge grinding. The traditional process of sizing carbide is to thrufeed the part in the hard state post sintering. This method requires many passes and a large grinding machine in order to achieve the tight tolerances required for drills. Glebar solved this problem by shaping the carbide in the soft state to near net size. As a fragile component, the consistency of chalk, care needs to be taken in handling the part while it is being ground and the PG-9X20DHD does this very well. The parts are then sintered and thru fed on a conventional grinder such as the GT-610. This unique process reduces throughput time, reduces the fallout rate and allows the ground carbide to be reclaimed and reused. The machine has also been adapted to point quartz glass used to produce fiber optic cable. Additionally it is used to grind wood components such as drumsticks.
