The recent trend in the Indian stone industry is marked by the arrival of automatic stone polishing machine for granite, slate, limestone etc. These machines are available in different configurations starting from 6-head, 9-head, 12-head, and upto 16 or 24 heads. The multi-head automatic stone polishing machine, offers high rate of production per hour, and reduce the turn around time for turning rough slabs into polished finished material.
The basic principle of the machine is the same. The rotating polishing heads are attached to a bridge, which controls the oscillating movement. Each head is equipped with a motor, and a revolving head, on which the abrasives are mounted. Sensors sense the edges and contours of the slab. The stone is passed below these heads on a conveyor belt. The heads then are act on the stone, and rise above once the edge passes below them. The pressure with which the heads act are also controlled individually.
The series of abrasives are mounted onto the head with the nearest head to the input trolley having the roughest grit, and the head nearest to the exit trolley having the finest grit, or buffing wheel. Generally an 8inch disc is ideal to be mounted onto the polishing head. The following video shows you the process of one such machine.
