摘要： An automatic tool changing device capable of cleaning a contact surface of a spindle, which is to be in contact with a tool holder, with a simple structure. The device includes a turret having a plurality of grippers on its outer circumference and holding the tool holder by means of the grippers. At the time of tool change, the grippers grip and pull out the tool holder fixed to the spindle. Rotation of the spindle causes the turret to rotate through a spindle gear, a turret gear, and a decelerating device, to thereby select a tool. At this moment, a coolant is spouted from a nozzle portion of a manifold toward a spindle taper hole in which the tool holder is interfitted and washes the taper hole. Due to the rotation of the spindle, the coolant is spouted onto the whole circumference of the taper hole, and the surface to be in contact with the tool holder is surely washed. Therefore, it is possible to perform the cleaning with a simple structure in which the nozzle portion is arranged near the spindle without machining the spindle and the tool holder.

摘要： A numerically controlled machine tool performs machining by rotating a rotational tool attached to a tool holder mounted on a spindle, with keys fitted into key grooves in the tool holder. The numerically controlled machine tool includes predetermined-amount rotating unit for stopping the tool holder at a predetermined rotational position and then rotating the tool holder by a given amount, and a distance sensor which is installed apart from the tool holder and measures a distance to the outer surface of the tool holder. The predetermined-amount rotating unit stops the tool holder at a rotational position at which the key grooves do not face the distance sensor, then rotates the tool holder by the given amount. The distance sensor measures the distance to the tool holder while the tool holder is rotating. The measurement result is compared with a reference distance or distances to discriminate between normal and abnormal rotational run-out of the tool holder.

摘要： For a spring sliding on the drawbar, the coil spring is used; the removal work for keeping the inner diameters of the coil springs aligned is performed such that the clearance between the outer diameter of the drawbar and the inner diameter of the coil spring becomes a minimum; and the coil springs are caused to be guided integrally with the drawbar. By doing so, the movement of the center of gravity of the spring that is caused by repeated rotational operation of the main spindle or repeated tool clamping operation will be reduced and the amplitude by vibration will be made smaller.

摘要： A tool holder is attached to a spindle by the contacting of the projecting cone part and end surface of the tool holder with the recessed cone part and end surface of the spindle respectively. A toroidal cone section is provided on the inner side surface of the recessed cone part of the spindle so as to protrude inward. The diameter of the toroidal cone section is formed smaller than the diameter of the section of the projecting cone part of the tool holder that abuts the toroidal cone section.

摘要： A feeder for a machine tool adapted to move a table relative to a saddle by rotation of a motor includes a ball thread nut fixed to the saddle and a ball thread shaft that engages with the ball thread nut in a rotatable manner but is immovable in an axial direction of the ball thread shaft relative to the table. The motor is fixed to the table and the ball thread shaft is coupled to the motor. A sum of a movable distance of the table relative to the saddle and a length of the saddle in the axial direction is shorter than a length of the table in the axial direction. The feeder further includes rails fixed to the table on its surface where the motor is fixed and bearings that are fixed to the saddle and bear the rails.

摘要： A stationary machine tool column supports a spindle head to be movable in an axial direction of the spindle. A table on which a workpiece is mounted is moved in directions orthogonal to the axial direction of the spindle. A cutting liquid feed device is fixed to the column through a support member and includes a cutting liquid nozzle and a shower nozzle. The cutting liquid nozzle is adapted to discharge cutting liquid toward a tool mounted to the spindle. The shower nozzle is adapted todischarge cutting liquid as a curtain of fluid to surround a cutting area.

摘要： A fixed first sleeve and a movable second sleeve are arranged in a center through hole of a main spindle. Balls at the rear end of the second sleeve engage a recessed slope of the first sleeve and a recessed slope of a draw bar, thereby amplifying the urging force of a spring for urging the draw bar upward. Balls at the distal end of the second sleeve hold and pull in the head of the pull stud with the amplified force. The pull stud has an axial through hole and a hole that connects with the through hole and opens sideways. Compressed air passes through these holes, thereby cleaning the respective taper surfaces and end faces of the main spindle and a tool shank. Switching means is used to close the hole that opens sideways, whereby a cutting fluid is allowed to flow through the axial through hole only.
