Abstract
The invention relates to a machine for creating non-cylindrical bore surfaces having a machine spindle (5), to which a machining tool (2-06, 3-04) can be connected, onto which a feed movement is transferred via a feed means (1-10). A direct axially parallel acting linear drive (1-06) is provided in the tool fitting unit (1) associated with the machine spindle (5) for fine feeding, the feed movement of which overlaps the first mentioned feed movement, and the actuating means (1-05) of which acts upon a feed (1-03) that is disposed together with the machining tool (2-05, 3-04) and the means for deflection (1-031, 1-032) of the feed movement in a tool unit (2, 3) that can be exchanged on the tool fitting unit (1).
