Abstract (en)
[origin: WO03097297A2] The spindle comprises a tubular housing (3) in which the spindle body is movable, the spindle body including a shaft (31) carrying a rotary abrasive tool head, and a cylinder for setting the position of the spindle on the metal structure (2); an electric motor and a drive connecting said motor to the spindle shaft; wherein, instead of said motor/drive assembly, two or more motors (21) are provided which are drivingly connected to the spindle shaft through gearing (24, 25) for evenly spreading the mass thereof and the drive torque, as well as for allowing the coolant supply line (29) through the hollow interior of the spindle shaft (27, 31); the spindle body (12) is coaxial with said cylinder actuator (35) an rigidly connected to the piston rod thereof; said tubular housing (3) can be swung around a spherical surface (4) supporting the end flange (5), the other end having a spherical guide band (8) for guiding the latter end across a mating cylindrical surface (9); and a clamping arrangement (7, 10) for locking the tubular housing (3) and the whole spindle (1) in a set position is provided.
