摘要： A grinding machine for machining workpieces includes a workpiece headstock and two grinding headstocks. A first grinding headstock has two grinding spindles each with one grinding wheel for grinding first and second planar and non-planar external surfaces. A second grinding headstock has a grinding spindle having a grinding wheel for grinding a central bore in the workpiece, and a clamping device to clamp the workpiece. First, the bore and the first planar and any non-planar external surface are ground on one side of the workpiece. Then, the workpiece is clamped in the bore. The second planar external surface can then be ground in the same grinding machine with one of the grinding wheels of the first headstock. The clamping device attached to the second grinding headstock is such that the central axis of the clamping device is exactly aligned with the central axis of the workpiece headstock.

摘要： A computer controlled grinding machine grinds a cylindrical region and an annular shoulder of a rotatable workpiece. Relative movement is effected between the workpiece and a grinding wheel along a line of action which subtends an angle of approach of less than 90 degrees to the Z axis of rotation of the workpiece. Such an angle of approach enables the wheel to grind the annular shoulder of the workpiece simultaneously with grinding the cylindrical portion.

摘要： A wafer is rotated on its axis, which is biased with regard to an axis of a grinding wheel, and revolves around an axis which is biased with regard to the axis of the wafer and the axis of the grinding wheel. In this state, the grinding wheel is abutted against the surface of the wafer. Thus, all abrasive grains on the grinding wheel can act on the whole surface of the wafer.

摘要： A process for manufacturing a field replaceable laser writer spindle assembly having a shaft with two ball bearings and a spindle head, comprises the steps of preloading both ball bearings to a predetermined level. The spindle head is rotated about a longitudinal axis of the spindle assembly, and a reference surface of the spindle head is ground to a predetermined tolerance for minimizing runout of the reference surface for producing the field replaceable spindle assembly.

摘要： A grinding tool adapted to be mounted on an end of an arbor and rotated thereby about an axis in contact with a workpiece is unitarily formed with a head and a foot. The head has a frustoconical front end face centered on the axis, turned away from the arbor, and tapering away from the arbor. It also has a frustoconical back face centered on the axis, turned toward the arbor, meeting the front face at an outer circular edge centered on the axis, tapering toward the arbor, and forming with the front face an acute angle. The foot has a frustoconical outer surface centered on the axis, meeting the back face at a front inner circular edge centered on the axis, tapering toward the front edge, and forming a right angle with the back face. The front and back faces of the head meet at the outer edge at an angle of about 45.degree..

摘要： A numerically controlled grinding machine provided with an angular type grinding wheel and a numerical controller for controlling the feed of grinding wheel based upon a control signal from a measuring head which measures the diameter of a cylindrical side of a workpiece. The grinding wheel is moved along an inclined path to grind the cylindrical side and a radially inner portion of the shoulder of the workpiece, simultaneously. In response to the control signal from the measuring head, the feeding of the grinding wheel is stopped. Then, the numerical controller detects the difference between a target position and a actual position of the grinding wheel along an axis of a work spindle. Further, the numerical controller compensates another target position to grind the radially outer portion of the shoulder for the difference. Thereafter, the grinding wheel is moved to the compensated target position so as to grind the radially outer portion of the shoulder.

摘要： A method of grinding a curved corner portion of a workpiece by a grinding wheel having a curved edge surface whose radius is smaller than that of said curved corner portion. The grinding wheel is movable along a path extending at an acute angle to the axis of rotation of the workpiece. First, the grinding wheel is relatively moved to a first grinding start position. Then, the grinding wheel is moved inwardly to an advanced position along the path so as to perform a plunge grinding operation, and is subsequently retracted to the grinding start position. After that, the grinding wheel and the workpiece are relatively moved so as to move the grinding start position to the next grinding start position along a curved arc which is in parallel with the curved corner portion of the workpiece. The above plunge grinding operation is repeatedly performed from each grinding start position thereby grinding the curved corner position.
