04 - SPECTRA

SPECTRA is the planetary calibrating machine designed by Pedrini for the thickness grinding of natural stone slabs such as marble, granite and quartzite. SPECTRA can process engineered materials as well.
SPECTRA is able to process slabs with a variable thickness from 10 to 100 mm and is available in two versions according to the slabs maximum machinable width.

SPECTRA B220ES
Maximum slab width: 2200 mm
Calibrating group diameter: 2350 mm
Independent tool-holding spindles: 24

SPECTRA B170ES
Maximum slab width: 1700 mm
Calibrating group diameter: 1850 mm
Independent tool-holding spindles: 18

Each SPECTRA calibrating group is composed of the exclusive Grifone head which uniformly works on the whole slab surface ensuring planarity and regularity of the final thickness.
The Grifone head is equipped with diamond tools radially placed on a circumference with a diameter larger than the processing width. The Grifone heads consist of a rotating structure on which a group of independent electro-spindles is mounted. Each electro-spindle is equipped with a 205mm-diameter diamond tool.
The slabs polishing lines that include SPECTRA can be customized to process just the slab upper surface or both surfaces.
