Abstract (en)
[origin: EP2165804A2] The machine has a clamping device (10) for fixing the machine at an end of a tube (2), and a grinding system (5) arranged at the clamping device. The grinding system is arranged outside of the tube, and has a grinder (20) movable along three axes (A, A', R, R', T, T') relative to the clamping device. The grinding system has distance sensors (80, 81) i.e. laser sensors, for measuring distance between the grinder and the tube at different positions along one of the three axes, and connected with the grinder. Another grinding system (5') is arranged within the tube. An independent claim is also included for a method for surface processing of ends of tubes.
