Abstract: The invention relates to a machine for machining the ends of pipes which, for control purposes, is assigned at least one computer unit and in the case of which the tools (13) are arranged displaceably such that they can engage radially in relation to the pipe in a tool head (11) which is driven by a motor (4) via a main spindle (10) guided through a headstock (6), the tool head rotating coaxially about the fixedly clamped pipe end, wherein the tools are arranged in tool holders in the form of slides (14A, 14B; 15A, 15B; 16A, 16B) and adjacent slides together mesh with a toothed wheel which is formed with weight compensation. According to the invention, the tool head (11) is formed with integrated advance motors (17) assigned to the slides (14A, 14B; 15A, 15B; 16A, 16B), and each slide is assigned a measuring device (24).
