摘要： PURPOSE:To improve the roundness of a stone by projecting on the inner peripheral face of a stone chip a plural number of very small mount with their seats positioned at a constant radial distance from the outer peripheral face of the stone chip, having these seats brought into contact with a metal disk and letting the inner peripheral face of the stone chip stuck on the metal disk. CONSTITUTION:A plural number of very small mounts 7 having their seats 7a positioned at a constant radial distance from the outer peripheral face of a stone chip 3 are projected on the inner peripheral face of the stone chip 3. A single stone layer is formed by bringing the seats 7a into contact with a metal disk 1 and sticking the inner peripheral face of the stone chip 3 on the metal disk 1. Since the mounts 7 allow concentric and high precision positioning and adhesion of stone chips 3 on the metal disk 1, the roundness of the stone can be improved. Furthermore, the peeling force acting on the adhesion plane due to the centrifugal force applied to the stone chips can be lessened to permit a high speed grinding as the stone layer consists of a single layer with a minimally required thickness only.

摘要： PURPOSE:To perform phase indexing while spindle is held rotating by furnishing a locating device for a phase converting shaft between this and the body of a chuck and by coupling a phase indexing motor with the shaft of a harmonic differential unit installed between the spindle and phase indexing shaft. CONSTITUTION:When a phase indexing motor 18 is operated in the condition that the spindle 2 is rotating, a shaft 17 will rotate to allow a harmonic differential unit 16 to rotate a phase indexing shaft 12 in a phase different from that of the spindle 2. The rotation is transmitted to a phase converting shaft 6, which is located on the body of the chuck by a locating device 11 in a position determined according to the phase angle of a crank pin P. This enables phase indexing while the spindle is held rotating, which should lead to enhancement of the production efficiency.

摘要： PURPOSE:To automatize a series of boring operation by attaching a tool holder to the tip of a hollow spindle driven by a belt, and changing positions of a concentric hollow rod and a concentric solid rod in the axial direction so as to fore them to make sizing and attachment/detachment of a tool, respectively. CONSTITUTION:A spindle 20 having, a head member 34 attached on its top displaceably in DE direction is rotated by a driving mechanism 12. Inside the spindle 20, rod members 22, 24, 28 are placed, 22 and 24 are fitted and fixed and are rotated together with the spindle 20. The member 28 does not rotate and engages with 24 by means of an engaging mechanism 26. And when it is moved in AB direction by a cylinder mechanism 14, its tip enters in and exits from an inclined bush 32 and changes the position of the head member 34 in DE direction. A holder member 28 is mounted on the head member 34 by a clamp mechanism 36, and is attached and detached as a result of the position change in AB direction caused by the unclamp mechanism 16 of an unclamp rod 30 placed inside rod members.

摘要： PURPOSE:To decide whether the operation of a variable vane is proper or not at the time of assembling by artificially bringing about the actual operation state of a turbocharger to test the switching state of the variable vane. CONSTITUTION:Receiving bases 14, 16, and 18 are provided on a base 12 of a test equipment 10, and a turbine part 100 of a turbocharger 110 with a variable vane is placed there and is held and fixed by a fixing part 28. A pressing part 34 is controlled to press and turn the variable vane 120, and the extent of displacement of the variable vane 120 is measured by a measuring part 36. By this equipment 10, the turning force equal to the pressure with which the exhaust gas of an engine presses the variable vane 120 is applied to the variable vane 120 to bring about the operation state of the turbocharger 110 from idling to acceleration, and the extent of displacement of the variable vane 120 is measured to decide whether the operation is proper or not. Thus, it is discriminated whether the operation of the driving part which operates the variable vane 120 through a link mechanism is proper or not.

摘要： PURPOSE:To make it possible to automate the first infeed of a grinding wheel to a workpiece to be ground with an exchanged grinding wheel by detecting by the sensor provided to a dress device that a dresser is brought into contact with the outer periphery of the grinding wheel to measure the outer diameter of the grinding wheel by use of the feed amount of the grinding wheel. CONSTITUTION:A dresser 46 is cross fed by a servo motor 49 after exchanging grinding wheels and positioned at an original position D0 above a grinding wheel 31. In the next step, when fed downward by a servo motor 48 and brought into contact with the other periphery of the grinding wheel 31 making a servo motor 5 become ON state, the dresser 46 stops its longitudinal feed according to the detected signal. And the radius R1 of a grinding wheel 3/1 is operated and measured on the basis of the longitudinal feed amount from the original position D0 of the dresser 46 to a present position D1. Then, the measured radius R of the grinding wheel 3/1 is judged to be proper or not, and if it is proper, dressing is performed, and if it is not, the reexchange of a grinding wheel is commanded and the grinding wheel 3/1 is exchanged to a grinding wheel 3/2. Thus, the diameter of the grinding wheel can be measured quickly and exactly after its exchange and the infeed of the grinding wheel can be automated.
