Abstract
An improved grinding apparatus includes a base (100) upon which a headstock (20) is mounted. A carriage (500) is movable along ways (101, 102) disposed on the base. A wheel slide (63) on the carriage rotatably support a grinding wheel (71). A first mounting plate (80) extends beneath a first footstock (400) and a first set of steadyrests (300) to a location adjacent to a headstock (20). While a workpiece is being ground, a second set of steadyrests (300) and a second footstock (400) are mounted on a second mounting plate (80). When the grinding operation has been completed, the first mounting plate is disconnected from the base (100) and removed from the grinding apparatus with the first set of steadyrests (300) and footstock (400). The second mounting plate (80) with the second set of steadyrests (300) and footstock (400) accurately positioned thereon are then inserted into the grinding apparatus.
