Rotating head with grinding wheels having oscillating segments, in a machine for polishing and lapping marble, granite and hard stone

摘要

The invention relates to the sector of machines for polishing marble, granite and hard stone in general. More precisely it relates to a rotating head with grinding wheels having oscillating segments, comprising a duct 6 able to convey, by means of the centrifugal effect, a lubricating fluid to moving mechanical members forming part of the head. The rotating head ensures perfect lubrication of all the moving parts and is also modular in the sense that it envisages the possibility of varying the number of elements supporting the grinding wheels 3 without having to make substantial modifications to the rotating head.
