Abstract

A spindle for tool heads used in calibrating, smoothing or polishing natural stone slabs and/or ceramic tiles, comprising: a tubular housing (3) in which the spindle body (12) is movable, the spindle body (12) including a shaft (31) carrying a rotary abrassive tool head at one end (32, 33), a cylinder actuator for setting the position of the spindle and its associated tool head on the metal supportstructure (2); two or more motors (21) drivingly connected to the spindle shaft through gearing (24, 25) for evenly spreading the mass thereof and the drive torque; a coolant supply line (29) to the abrasive tooling of said head through the hollow interior of the spindle shaft (27, 31); wherein said spindle body (12) is coaxial with said cylinder actuator (35) an rigidly connected to the piston rod thereof; moreover 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 clamping arrangement (7, 10) for locking the tubular housing (3) and the whole spindle (1) in a set position is provided.
