Claims

[Scope of utility model registration request]

A saddle is mounted on the bed so as to be slidable in the left-right direction, a table for mounting a workpiece is mounted on the saddle so as to be slidable in the front-back direction, a column is erected and fixed at the rear of the bed, and one of the columns is fixed. In a machine tool in which a spindle head is mounted on the side of the column so that it can be raised and lowered, and the spindle is mounted on the spindle head so that the spindle can be rotated and moved back and forth, the column is installed at the rear of the side opposite to the side on which the spindle head is attached. a tool magazine, a rail arranged in a substantially L shape from the front of the column to the other side between the spindle head and the tool magazine; A drive chain having a forward and reverse drive means and a central part of a tool changing arm having tool gripping claws at symmetrical positions at both ends are supported so as to be rotatable 180 degrees, and the drive chain moves the tool along the rail via wheels. An automatic tool change for a machine tool comprising a tool carrier movable between a magazine and a spindle head, and characterized in that the tool carrier is kept on standby on the other side of the column except when changing tools.
