Method and machine tool for the finish machining of cylinder bores

摘要

A process for the finish machining of cylinder bores (11, 12, 31, 32, 17, 18) by machining on a machine tool, which a tool support (3, 25, 26) having at least in a direction of advance (4, 27, 28) is movable, in that the finish machining with a cutting tool (13, 14, 29) that a geometrically defined cutting edge (15, 30) and at the outer end of a tool spindle (8, 9, 23, 24) is provided, which can be driven to rotate by a motor in a housing (6, 7, 21, 22) is magnetically supported on the tool support (3, 25, 26) is fastened, by the movement of the cutting tool (13, 14, 29) in a direction orthogonal to the feed direction (4, 27, 28), in the spindle (8, 9, 23, 24) and the feed movement of the tool spindle (8, 9, 23, 24) in the orthogonal direction over the magnetic bearing assembly in the housing (6, 7, 21, 22), characterized in that the cutting forces on the cutting edge (15, 30) on the basis of..
