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.

Tool magazine device and machine tool

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.

Horizontal machine tool

A horizontal machine tool () includes a base frame () where workpiece support faces () for supporting a workpiece are formed at front portions; an X-axis saddle () attached to a back-face portion () of the base frame () through an X-axis movement mechanism () universally slidably in a left-right direction; a Y-axis saddle () attached to the X-axis saddle () through a Y-axis movement mechanism () universally slidably in an up-down direction; and a spindle device () attached to the Y-axis saddle () through a Z-axis movement mechanism () 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.
