Abstract
An abrasive grinding wheel having an annular grinding face depending from a substantially circular body includes a tubular inner wall which defines an axial bore configured to convey coolant in a downstream direction therethrough. The inner wall is coupled to a concave body portion terminating at an inner periphery of the annular grinding face. A flange having an outer periphery disposed, in representative embodiments, within about 20 mm of the inner periphery of the grinding face, is superposed with the concave body portion, to define a fluid flow passage between the flange and the concave body portion. The fluid flow passage is in fluid communication with the axial bore and with the grinding face, so that during operable rotation of the grinding wheel, coolant flowing downstream through the bore is conveyed radially outward into the fluid flow passage for delivery to the grinding face.
