<p>PURPOSE:To increase the number of heads and speed for the exchange thereof without any increase in installation area by exchanging a ganghead between a turning body for vertical indexing about a horizontal axis and a revolving body for forward indexing thereafter upward about a vertical axis. CONSTITUTION:A predetermined ganghead H hooked to a turning body 25 is indexed to a downward position B, advances as mounted to a drive head 12, hooked to the turning body 25 after machining a workpiece and then the head to be used is indexed to the downward position B. An unnecessary head H is indexed to an upward position A, hooked to the guide support 50 of a transfer device 40, Indexed to a forward position C through the turning of a turntable 41 about a horizontal axis 45 and hooked to the revolving body 33 of a magazine 30. And a head H to be used next is indexed to the forward position C through the turning of the revolving body 33, hooked to the guide support 50 of the transfer device 40 and hooked to the revolving body 25 through the turning of the turntable 41.</p> |
