The oscillation of the bridge of a traditional polishing machine that moves several spindles at the same time represents a limit especially for irregular slabs. For this reason, SIMEC presents to the polishing market the ORBITAL series featuring an oscillating and independent movement of each spindle. As a matter of fact, in the ORBITAL polishing machines there is no longer a single oscillating bridge but several bridges on which the spindles move individually making movements on different axes, similar to the ones performed by a manual processing and above all perfectly reaching the edge of the most irregular slabs without having to lift the other heads and in this way tools totally spend more time on the material.
