Title:
MACHINE TOOL
Document Type and Number:
WIPO Patent Application WO/2018/109974
Kind Code:
A1
Abstract:
A horizontal machining center comprises: a main spindle to which a tool can be mounted; a tool clamping device (41) that clamps the tool to the main spindle; a tool clamp detector (44) that detects the clamped state of the tool by the tool clamping device (41); a tool exchanging mechanism (42) that exchanges the tool mounted to the main spindle (22); and a control unit (52) that operates the tool exchanging mechanism (42) to exchange a first tool with a second tool that is the same type as the first tool when the clamp state of the first tool in the main spindle (22) is detected to be abnormal with the tool clamp detector (44). By virtue of such a configuration, a machine tool is provided for which productivity is not significantly reduced even if the tool clamp state is detected to be abnormal.
