A grinding fluid feeder apparatus for a grinding machine for machining a spiral bevel gear in which a tapered annular grinding portion is formed of conical grinding faces provided on the inner and outer circumferences of an annular grinding wheel and a tooth surface of a workpiece is ground by said conical grinding faces. The feeder apparatus includes a feeder block having a groove portion allowing the annular grinding portion to sink thereinto and a sump provided on a side surface of the groove portion, a grinding fluid feed passage communicating with the groove portion, and a cover plate provided at one of the openings of the groove portion on an end surface of the feeder block so as to abut on the annular grinding portion. The feeder block is disposed to have the other of the openings of the groove portion abut on a tooth space of the workpiece. |
