Abstract: A machine tool has a mechatronic assembly which has a machine spindle and has a tool head which is held on the machine spindle and which has a basic body and also at least one working slide, which is adjustable relative to the basic body, for holding a tool. The mechatronic assembly contains an electric adjusting motor which acts on the working slide. The machine tool has a support device which holds the mechatronic assembly and which has an articulated joint arrangement at which the mechatronic assembly can be pivoted at least about a first axis and about a second axis which differs from the first axis.

Abstract: The invention relates to a machine tool (100), in particular for machining valve seats (102) on cylinder heads. The machine tool (100) has a mechatronic assembly (10) which has a machine spindle (12). The machine tool (100) comprises a tool head (18) which is held on the machine spindle (12) and which has a basic body (20) and also at least one working slide (22), which is adjustable relative to the basic body (20), for holding a tool (23). The mechatronic assembly comprises an electric adjusting motor (24) which acts on the working slide (22). The machine tool (100) has a support device (106) which holds the mechatronic assembly (10) and which has an articulated joint arrangement (110) at which the mechatronic assembly (10) can be pivoted at least about a first axis (114) and about a second axis (116) which differs from the first axis (114).
