摘要： An electric path (E) is formed by connecting a spindle (11), a tool (12), a table (4), a base (2), a column (5) and a housing (13) including a capacitor (C0) having the spindle (11) and the housing (13) as electrodes, and electric current is sent to the electric path (E) by a current generator (51). An electro-capacitance change is detected by measuring a current value in the electric path (E) by an electro-capacitance detector (52) to detect a state of a bearing gap between the spindle (11) and the housing (13). No multiple sensors are necessary and the spindle state detector (50) can be simplified.

摘要： A mechanism for detachably mounting any selected one of several attachments to a hollow spindlehead ram within which a spindle is rotatably supported by a hollow shaft, the latter being capable of both rotary and axial displacement relative to the ram. Both the hollow shaft and the selected attachment are coupled with the ram via Curvic coupling teeth. Further, in order to retain the attachment in positive engagement with the ram via the Curvic coupling teeth, a series of external locking teeth are formed on the hollow shaft at constant circumferential spacings for engagement with a series of internal locking teeth formed on the attachment. The hollow shaft forces the attachment against the ram via the interengaged locking teeth under hydraulic pressure.

摘要： A portion (14a, 14b) of a chip remover (14) is defined to be vibratory to give an NC machine tool (MT 1) a vibration transferable onto a surface (FS) of a work (13) under a finishing by the NC machine tool (MT1), a decision is made whether the NC machine tool (MT1) enters the finishing, and vibration of the vibratory portion (14a, 14b) is controlled, as the decision is true. A chip removal method and an NC machine tool equipped with a spiral chip remover (113) as a chip remover have various chip removal rules for determining permission/prohibition of the operation of the spiral chip remover (113). This spiral chip remover (113) operates based on commands described in a machining program. When a command in the machining program is executed, the permission/prohibition of the operation of the spiral chip remover (113) is controlled according to the chip removal rules.

摘要： A spindle 51 capable of controlling quantitatively the rotational angle around the center axial line itself is mounted with a turning tool 50; the spindle 51 and a workpiece are allowed to be relatively dislocated by an axial control along at least a plane perpendicular to the rotation axial line of the spindle 51 in such a manner that the relative movement locus L of the spindle center Cs to the workpiece conforms to a geometry to be machined and a required front rake angle .beta. is set, thereby allowing a mutual interpolation motion between the spindle and the workpiece to be performed; and the rotational angle of the spindle 51 is synchronously controlled with a required interrelation to the above-mentioned axial control, whereby the direction of the cutting edge of the turning tool 50 to the machined face of the workpiece is kept at a required direction at the full rotational angle position of the spindle 50 with the required front rake angle .beta., and the direction of the cutting edge of the turning tool 50 to the machined face of the workpiece W is kept at a required direction, and then the workpiece W is machined into a geometry determined by the interpolation locus L due to the above-mentioned mutual interpolation motion.
