A machine tool (10) intended for machining components on site comprises a frame (12) mounted on bearings (14, 16). Each bearing (14, 16) comprises an inner fixed bearing (14C, 14D, 16C, 16D) clamped to a work piece (22) and an outer rotatable bearing (14A, 14B, 16A, 16B). The frame (12) supports one or more spindles (74) having two cutting tools (82, 84) which are driven by air motors (76) through gear boxes (78). The frame (12) is driven by an air motor (60) through a reduction gear box (56) and annular gear (54). The bearings (14, 16) are both split to enable the machine to be assembled around a work piece (22) so that the tool can machine diameters (22A, 22B).
