Abstract

The spindle (9) of a machine tool carries a boring device provided with a boring bar (1) and with a tool (2). The boring bar (1) is connected to a back plate (8) of the spindle (9) by means of torsion bars (3). A support arm (11) fixed to the boring bar (1) bears on a low gradient surface (14) of an adjusting body (16) which may be moved axially in a guide (17) by a thrust bar (23) to impact a radial motion to the tool (2). Facing the inclined surface (14) there is provided a second inclined surface (15) between which the support arm (11) is positively guided. The radial adjustment of the tool (2) allows the clearing of the tool (2) from a machined surface during the backward motion of the tool and the compensation of the wear of the tool during a following machining operation.
