Abstract:
A method of grinding cutting blades with a grinding wheel having first and second grinding edges. The method comprises rough grinding at least one surface of the cutting blade with the first grinding edge and finish grinding at least one surface of the cutting blade with the second grinding edge.
Abstract:
A method of grinding a cutter for skive-machining a work and a device for grinding the skive-machining cutter which method and device allow formation of a better gear with a cutting operation. The target of grinding is a skive-machining cutter in which a plurality of helical groove portions are formed. A first grinding step is effected for grinding one of a pair of blade lateral faces facing the groove portion. A second grinding step is effected for grinding the other of the pair of blade lateral faces. Then, a third grinding step is effected for forming a blade tip face to be continuous with the blade lateral face formed in the first grinding step and the blade lateral face formed in the second grinding step.
Abstract:
THE DISCLOSURE EMBRACES A GRINDING APPARATUS OR MACHINE ESPECIALLY ADAPTED FOR GRINDING THE TEETH OF TOOTHED CUTTERS OR WORKPIECES WHEREIN THE RAM CARRYING THE GRINDING WHEEL IS RECIPROCATED IN A STRAIGHT LINE, THE GRINDING APPARATUS INCLUDING A UNIVERSALLY MOUNTED WORKPIECE OR CUTTER SUPPORT FOR GRINDING TEETH OF VARIOUS ANGULARITIES, THE CUTTER BEING AUTOMATICALLY INDEXED BETWEEN SUCCESSIVE GRINDING STROKES AND THE GRINDING APPARATUS AUTOMATICALLY BROUGHT TO REST UPON COMPLETION OF GRINDING OPERATIONS ON A CUTTER OR WORKPIECE.
Abstract:
A coolant delivery apparatus for a machine tool wherein the position of the coolant delivery apparatus is controllable such that coolant may be delivered to the machining contact zone of a tool even though the location of the machining zone of the tool may change such as during machining of a workpiece, or from one workpiece to another.
Abstract:
A fixture is disclosed for grinding involute teeth profiles in a gear blank. Each tooth is generated by reciprocating the gear blank tangentially with respect to the grinding edge of a rotating wheel while oscillating the blank about its axis as the axis is constrained to move in a plane that is parallel to the axis of the grinding wheel.
