    Abstract: A grinding machine has a base and a pair of work support bars journalled within the base. A table is journalled with the support bars in such fashion that it is axially movable along the parallel spaced bars and pivotable around one bar central axis while the other bar is radially displaced relative to the base. A pair of ramp surfaces having ramp planes disposed transversely to the pivot axis of the table are provided on the radially movable bar, such that a wedge feed is accomplished by relatively moving a powered wedging device along the ramp plane to thus radially move the movable bar, thereby causing table feed movement with respect to the base. A work support head stock is preferably carried on the base, and a wheelhead having a rotable grinding wheel is carried on the table, so that pivotal movement of the table causes relative feed movement of the grinding wheel with respect to a supported workpiece.

    Abstract: A grinding machine having a movable workhead for carrying a workpiece and a movable wheelhead for carrying a grinding wheel, the workhead and the wheelhead being axially movable along intersecting paths. The wheelhead is provided with a lead screw drive in which the screw is fixed against rotation and the nut carried by the wheelhead platform is rotated by a gear drive but is fixed axially. This drive is used to provide micrometric movement. The screw terminates at one end in a piston in a hydraulic cylinder, this providing piston/cylinder drive for large amounts of wheelhead movement. Workhead feed is provided by a rotatable and axially displaceable spindle drive by a step-by-step electric motor through a gear train that converts the rotary motion output of the electric motion to corresponding axial movement of the spindle. .Iadd.

    Abstract: A device for indicating the touching of a grinding wheel and a workpiece. On a shaft connected to a spindle of a grinding wheel there is fixed a radially slotted or gear wheel. On the shaft there is also rotatably mounted another identical slotted wheel, which is connected by means of a spring to the shaft, and a stable supporting plate provided with magnetic scanning heads situated over the respective gear wheels. The thus mounted slotted wheels, which are made of magnetic metal, such as steel, the scanning heads, and the phase meter function to detect changes in speed of the grinding wheel. The outputs of the scanning heads are connected to a phase meter, the output of which, after being amplified, controls the in-feed speed of the grinding wheel.

    Abstract: A grinding machine includes means for changing the feed rate of a grinding wheel relative to a workpiece when the grinding wheel approaches the workpiece. The grinding wheel is insulatedly mounted on a wheel slide which is moved by a feed device toward and away from the workpiece. An electrode device is mounted adjacent to the grinding wheel and is connected to an electric power source for generating a difference of potential between the grinding wheel and the workpiece. A detecting device detects the change of the difference of potential caused by the approach of the grinding wheel to the workpiece to generate a control signal. A control device controls the feed device so as to change the feed rate of the wheel slide in accordance with the control signal.
