    摘要： A bell-crank lever (24) is pivotally attached to a spindle head (10) in such a manner that it pushes down an upper end (18a) of a drawbar (18) for loading and unloading a tool, which is provided within a rotating spindle (14) received in the spindle head (10) of the machining center. An end portion of one of the arms of the lever (24) is arranged so that it can engage with a guide cam (28), and an end portion of the other arm is formed as a projecting spherical pressure end portion (24a) which is not connected mechanically to the upper end (18a) of the drawbar (18). The lever (24) is constantly urged toward the guide cam (28) by a spring means (32).

    摘要： Described is a novel spindle mounting assembly for use with a computer numeric controlled (CNC) machine, such as a drill tap machine. In one example an auto changer spindle mounting assembly includes a collar with a gas inlet. The collar defines a collar opening therethrough to create a passage between the first side of the collar with the second side of the collar. The collar further includes a passage in fluid communication between the gas inlet and through a nipple to the collar opening. The mounting assembly includes a manifold body with a gas outlet adapted to mate with the gas inlet of the collar, the manifold body defined a passage in fluid communications between, the gas outlet and a manifold body inlet. Also included is at least one extension bar, adapted to mechanically fasten to the manifold body to a computer controlled machine.

    摘要： The present invention provides a machine tool which reliably prevents the rotation and the movement of a turning tool to be attached to a rotatable main shaft via a tool holder with a simple configuration, and which permits a turning process with high process precision, and provides such a tool holder.
    In a machine tool (1) that attaches tools (3) for rotation process and turning process via a tool holder (30) to an end part of a main shaft (20) which is supported by a main-shaft head (2) and rotates about its central axis, a rotation locking flange (31) is provided on an outer circumference of the tool holder (30) holding the tool (3) to widen outward in a radial direction. Two engaging holes aligned on a circumference of a circle coaxial with the tool holder (30) are formed in the rotation locking flange (31), and the engaging holes are engaged with two engaging projections (23) projecting from a lower face of the main-shaft head (2), and thereby the rotation and the movement in a radial direction of the tool holder (30) are prevented.

    摘要： The position of a feed shaft is monitored and the average moving speed and moving frequency of the feed shaft are obtained every position correction unit time. A correction value delta n is obtained using an approximate expression from the obtained speed and frequency (c7 and c8) and updated. A position correction value for a command position is obtained from the correction value and the command position is corrected by the position correction value. When the power is turned on again, an initial correction value is obtained from the power off time and stored (c1 - c6). A position correction value for a command position is obtained from the initial correction value and the command position is corrected by the position correction value. Since the correction value is obtained by using the approximate expression, no sensor is necessary and hence the thermal displacement can be corrected at all times. If the change of the correction value is large (c10), the thermal displacement value is measured with a sensor to obtain a correction value (c11 and c12) to improve the precision. The number of measurements with the sensor is reduced and the machining time can be reduced.
