Pedrini Gresline M644 Thickness Calibrating, Levelling, Polishing Machine

The gauging/levelling machine M644CV makes use of Pedrini patented exclusive technology to remove up to 3.600.000 mm3 per minute of tiles surface layer, causing no tiles break.
As examples, M644CV performs 0.8 mm deep thickness gauging/levelling operation at the speed of 7.5 mt min on 600x600mm tiles and 11 mt/min on 400x400mm
At machine entry ,the unit D.G.S. ( Deep Grooving System) removes 85% of tiles surface layer with the use at deferred time of two diamond discs sets ,that dig parallel grooves ,very close each other ,at levelling depth .
The remaining 15% ,represented by very thin ridges ,is removed through a number of Aquila heads ,equipped with diamond satellite tools , that generate a finish degree that can be attached by semi fine grit abrasives in the next polishing phase .
