摘要： A device for detecting a position of an edge of a cutting tool includes a reference plate positioned to form a slit between the edge of the cutting tool and the reference plate. The slit extends in a direction transverse to the longitudinal direction of the cutting tool. A laser light source is provided to irradiate a laser light to the slit. A detecting device detects a diffraction pattern created through diffraction of the laser light by the slit. A processing device is provided to determine the position of the edge of the cutting tool based on an output signal of the detecting device.

摘要： An apparatus for machining a non-circular workpiece, wherein the profile data of plural sections of the workpiece stored in the profile data storage means are transformed into the frequency functions of 1 to n degree which is a function of the rotary angular velocity of the workpiece. The calculation means finds the amplitudes and the phases of each degree of the frequency function of each of plural intermediate sections by means of the interpolation according to the position between selected two sections based on the frequency functions of the selected two sections so as to obtain high frequency functions and low frequency functions which are then converted to high frequency and low frequency profile data. The machining apparatus actuates a linear motor in accordance with the high frequency profile data and actuates a PZT actuator in accordance with the low frequency profile data. The actuations of these actuators are accomplished in a synchronized relationship with the rotation of the workpiece to machine the workpiece into a non-circular shape whose sectional shape changes with respect to its axial position.

摘要： A feed mechanism is constructed with a piezoelectric actuator embedded in the front end of a square sliding shaft, which is supported by hydrostatic guide surfaces formed on a guide base for sliding motion in the axial direction. A cooling jacket having a helical channel on its outside surface is provided at the periphery of the piezoelectric actuator. A part of pressurized fluid fed to the hydrostatic guide surfaces is led to the helical channel of the cooling jacket through a cooling oil feeding channel formed in the sliding shaft, and fluid in the helical channel is drained to a low pressure space through an oil discharging channel formed in the sliding shaft.

摘要： A slide guided on a guiding member has at least one sliding surface in slidable engagement with a guiding surface of the guiding member. The at least one sliding surface is formed with an elongate supply grove extending in the sliding direction of the slide and is also formed with a plurality of hydrostatic pressure pockets arranged in the sliding direction of the slide. The slide is formed therein with passages which respectively provide fluid communications of the hydrostatic pressure pockets with the elongate supply groove, and a plurality of throttle elements are respectively fitted in the passages at portions of the same opening to the hydrostatic pressure pockets. A supply passage connected to an oil supply is formed in the guiding member and at the guiding surface, opens to the elongate supply groove for always communicating with the elongate supply groove irrespective of the sliding position of the slide.
