Polishing head for surfaces of stone material

摘要

A polishing head (1) is described, for plane surfaces of stone material, composed of: a slow transmission assembly (2); and a series of quick transmission assemblies (3) connected to a series of tool-carrier assemblies (4) arranged on a circumference (6) orthogonal to a main axis of the head (1) constituted by a central shaft (20); in which the tool-carrier assemblies (4) are adapted to move at an absolute peripheral speed that comprises a high radial component.
