Abstract (en)

[origin: EP3628442A1] A multi-tool aggregate unit (TU1) for a polishing head (H1) of an electronically-controlled polishing machine, for polishing edges of plate of stone material or synthetic material, such as for finishing operations in the mass production of kitchen tops or the like, comprises an aligned series of polishing tools (11) adapted to carry out progressively finer machining operations, the tools being arranged according to an order corresponding to the progression of the machining operation, with a tool (11) for the most coarse machining operation arranged at one end of the series and a tool (11) for the finest machining operation arranged at the opposite end. The supporting structure (9) of the multi-tool aggregate unit (TU1) rotatably supports a single driving rotating shaft (12) which is connected in rotation with all the tools (11) by means of a gear transmission (13,14). The driving rotating shaft (12) has an end conical shank (12A) configured to be removably connected in rotation within an end conical receptacle of a motorized spindle of a polishing head (H1) of the polishing machine, so that said spindle drives in rotation all the tools (11) of the multi-tool aggregate unit (TU1) while at the same time supporting the weight of said multi-tool unit. The supporting structure (9) of the multi-tool aggregate unit (TU1) is configured to engage the spindle supporting body to prevent a rotation of the supporting structure (9) of the multi-tool unit around the axis of the spindle.
