Abstract: A machine tool includes a trough which collects chips; a mobile unit which is located above the trough and moves in the longitudinal direction of the trough on a bed, is configured from a first beam member, a second beam member, and a connecting member connecting the first beam member and the second beam member, and is formed with a hollow that opens toward the trough from above; a first guide which supports the mobile unit in such a manner that the mobile unit is movable in the longitudinal direction of the trough; a second guide which faces the first guide across the trough, and supports the mobile unit in such a manner that the mobile unit is movable in the longitudinal direction of the trough; and a cradle, both ends of which are supported by the first beam member and the second beam member.

Abstract: An upright machining center is characterized in being provided with: x-axis guides for moving and guiding a table in the left-right direction on a bed; a column provided on the bed and provided with an opening that straddles the x-axis guides in the front-back direction so that a moving body, on which the table is provided, can enter therein in the left-right direction; a saddle, which is disposed on the upper part of the column so as to be movable in the front-back direction and for which a first y-axis guide that extends in the front-back direction on the right side of the left-right direction and a left second y-axis guide that is located lower and parallel thereto are provided; and a main shaft head, which is disposed on the left side surface of the saddle and moves in the vertical direction.

Abstract: A machine tool including a tool magazine (20) arranged in a storage region adjacent to a working region of a workpiece to store a working tool (31) for working the workpiece and a measurement tool (32) for measuring the workpiece; a spindle (10) to which the working tool and the measurement tool are attached in a detachable manner, the spindle being provided in a movable manner relative to the workpiece; a shutter (40) provided between the working region and the storage region in an openable and closable manner; a transceiver (51) attached to the measurement tool; and a communication module (52) arranged in the storage region to communicate with the transceiver of the measurement tool attached to the spindle.

Abstract: The present invention provides a safety device for a rotating feed rod, the safety device preventing the accidental rotation of the rotating feed rod and being provided with: a rotating member which is provided in any rotating shaft of a power transmission mechanism of the rotating feed rod and in which a plurality of openings are formed in the circumferential direction thereof; and at least two plunger pins which are disposed apart from each other in the circumferential direction of the rotating member in a housing of the rotating feed rod and provided to be movable forward and backward so as to be accepted in the openings of the rotating member. Even when the rotating shaft is indexed at an arbitrarily defined rotational position, at least one plunger pin among the plunger pins is accepted in the opening.

Abstract: The present invention provides a safety device for a rotating feed rod, the safety device preventing the abnormal rotation of the rotating feed rod and being provided with: a rotating member (102, 202) which is provided in any rotating shaft (50, 80) of a power transmission mechanism of the rotating feed rod and in which a plurality of openings (102a, 202a) are formed in the circumferential direction thereof; and at least two plunger pins (104, 106: 204, 206) which are disposed apart from each other in the circumferential direction of the rotating member in a housing (54, 62) of the rotating feed rod and provided to be movable forward and backward so as to be accepted in the openings of the rotating member. Even when the rotating shaft is indexed at an arbitrarily defined rotational position, at least one plunger pin among the plunger pins is accepted in the opening.
