Pedrini Supernova B065MV/B080MV/B100MV Calibrating/Polishing machine for marble and travertine strips

Machine for calibrating and polishing marble and travertine strips. It is available with a number of calibrating and/or polishing heads varying according to the needs. All the versions with polishing head are equipped with movable beam with adjustable width and speed. Available working width: 650, 800 and 1000 mm. Independent calibrating heads with cast iron structure, polishing heads rising and lowering driven through double pneumatic piston. Spindles ROTOR and counterpressure system are standard equipment on all polishing heads.
CONTINUOUS BELT POLISHING MACHINE FOR MARBLE, TRAVERTINE AND STONES. This highly efficient machine has been designed for thickness gauging and polishing of strips with trimmed ends and max width dimensions 650 mm. The selection of the operational elements which form Supernova B065MV, their top level efficiency and reliability are the result of an experience which has matured throughout the technological evolution of more than 1,000 polishing machines manufactured in the past 25 years by Pedrini. The new Supernova B065MV, reinforced with exclusive technology, achieves top production speeds, whilst reducing consumption, maintenance and depreciation.
All components have undergone structural inspection through the FEM (Finite Element Method). The structural component surfaces are protected with three coats applied after sandblasting, while the small parts undergo a cataphoresis corrosionproofing treatment.
The polishing plates are driven through patented ROTOR spindles, that have been built as mono block systems with controlled vertical sliding. ROTOR spindles direct drive system avoids radial stress on the spindle bearings, increases their life signifi cantly whilst saving about 15% of the absorbed energy and does not need maintenance. The mono block system has the centre of gravity on the spindle rotation axis and its considerable weight, that is controlled by counter-pressure, stabilizes polishing plate action. quality with the lowest tool consumption. The ROTOR spindles are equipped with an easyto-use individual device for the precision centring to the processing plane. The polishing plates, that are utilized within optimal operative conditions, realize the best polishing
