Abstract: A tool magazine device includes a rail that is annularly formed and that has a separation section at a part in a circumferential direction of the rail and a holding ring that is arranged coaxially with the rail and that is rotated by a driving motor. The holding ring is provided with a plurality of holding sections that are open in an axial direction of the holding ring. The holding sections are arranged in the circumferential direction of the holding ring. A tool pot is held to be insertable into and extractable from each holding section. A conveyance unit sends out the tool pot placed in the holding section to an exchange position and sends the tool pot into the holding section from the exchange position. A roller supported by each tool pot rolls on the rail in response to the rotation of the holding ring.

Abstract: Provided is a horizontal machine tool with a base frame including a base part and a saddle supporting part vertically standing on the base part; an X-axis saddle mounted on the back face of the saddle supporting part and capable of sliding in the left-right direction via an X-axis translation mechanism; a Y-axis saddle mounted on the X-axis saddle and capable of sliding in the up-down direction via a Y-axis translation mechanism; and a spindle device mounted on the Y-axis saddle and capable of sliding in the front-rear direction via a Z-axis translation mechanism. The horizontal machine tool is adapted such that a workpiece supporting member is installed on the base part in front of the saddle supporting part. This configuration can reduce the size and weight of the entire construction.

Abstract: A horizontal machine tool (1) includes a base frame (10) where workpiece support faces (11c) for supporting a workpiece are formed at front portions; an X-axis saddle (20) attached to a back-face portion (12b) of the base frame (10) through an X-axis movement mechanism (50) universally slidably in a left-right direction; a Y-axis saddle (30) attached to the X-axis saddle (20) through a Y-axis movement mechanism (60) universally slidably in an up-down direction; and a spindle device (40) attached to the Y-axis saddle (30) through a Z-axis movement mechanism (70) universally slidably in a front-rear direction. According to this configuration, it is possible to make a whole of the horizontal machine tool a small size and lightweight and to enhance machining accuracy of the workpiece.
