ABSTRACT:
A centerless grinding machine which comprises a grinding wheel, a regulating wheel, a blade and an inprocess gaging device and in which said gaging device includes a pair of feelers each having a contact adapted to contact each one of the wheels and the blade is provided with a rectangular opening or slot having dimensions sufficient to freely receive the contacts so that interference between the wheels, blade workpieces and contacts is prevented. One of said feelers contacts the periphery of said grinding wheel in a peripheral position below by the distance of center height of the workpiece and the other feeler contacts the periphery of said regulating wheel in a position below the position where the first-mentioned feeler contacts the periphery of the grinding wheel.
