Abstract: A centerless grinding machine comprising a grinding wheel on a rotational sleeve supported by a hydrostatic bearing means on a stationary spindle fixed to a grinding wheel table, a regulating wheel supported by a hydrostatic bearing on a spindle fixed to a regulating wheel table, and a blade for supporting a workpiece. Both wheel tables supporting the corresponding wheel are guided along a hydrodynamic sliding guide way to which a uniform pre-load is applied by hydrostatic bearings, and a servo mechanism is provided to compensate for frictional forces generated on the feed guide way, whereby it is possible to accomplish fine positioning of the corresponding wheel table and to grind the outer periphery of the workpiece with high precision and efficiency.

Abstract: A rotary table unit having a stationary base element and a table element rotatably mounted on the stationary base element is provided with hydrostatic and hydrodynamic bearing guides forming a composite bearing guide mechanism for enabling smooth and stable rotation of the table element under application of local load to the table element. The rotary table unit is also provided with a main drive motor for rotating the table element and an auxiliary drive motor for supplementing a drive force of the main drive motor in response to a change in load applied to the table element.

Abstract: A direct-acting table mechanism in which tables are driven without any contact by use of a hydrostatic fluid for thrust-transmitting the tables in their sliding direction. The tables are hydrostatically supported on hydrostatic guides on a bed, and differential pressures are supplied to the hydrostatically supporting portions to control the attitude of the tables. This table mechanism is of high degree of accuracy uninfluenced by errors in the feed screw system, high rigidity and thus permits highly stable fine feed.

Abstract: A measuring device for oblique angle which is wide in the range of measurement and is high in measuring accuracy, wherein an oblique table is controlled in such a way that the oblique table static-pressure supported is subjected to servo-control so that a detection signal of an oblique angle detector is zero, and an oblique angle is measured by the control signal.

Abstract: Disclosed is a method of producing a grinding wheel by electroplating. A part of the outer peripheral portion of a grinding wheel body is immersed in a plating solution. While rotating the grinding wheel body at a low speed, electric current is supplied to flow between an anode disposed in the plating solution and a cathode contacting the grinding wheel body, so that a pre-plating layer of uniform thickness is formed on the outer peripheral surface of the grinding wheel body. Plating operation is continued while adhering abrasive grains to the pre-plating layer to further cause a precipitation of a plating layer to temporarily fix the abrasive grains. The abrasive grains are then pressed by a pressing roller so as to be forcibly embedded into the pre-plating layer by making an effective use of plastic deformation of the pre-plating layer, thereby to obtain a uniform projection height of the abrasive grains from the surface of the grinding wheel.

Abstract: A servo control system which can automatically control a position of a hydrostatically supported member such as a table of a machine tool, rotary shaft or the like is disclosed. The system comprises a closed loop control system including a differential amplifier for effecting a subtraction operation between an amount of displacement of a member and an amount of reference signal and a servo amplifier delivering a control signal and a servovalve for supplying operating pressure upon receipt of the control signal to the member, whereby the position of the member is controlled by the pressure applied thereto.
