STANDARDS: EN 12390-2 | ASTM D4543 | UNI 6132
Designed to grind and polish concrete cube and cylinder specimens,
blocks, natural stones, rocks, ceramic materials etc.
Specimens are easily fixed to the table by proper locking stirrups
(see accessories) allowing to grind at a time:
– n° 3 cube specimens 100 mm side, or
– n° 3 cube specimens 150 mm side, or
– n° 2 cube specimens 200 mm side, or
– n° 2 cylinder specimens Ø 100×200, 110×220, 150×300,
160×320 mm, or
– n° 1 block with max. dimensions 390×250 mm
The radial mouvement of the head is equipped with end of stroke
system, granting the fully automatic displacament in both directions.
The column is completely protected against the abrasive dust.
The vertical lowering of the grinding head is achieved with infinitesimal
adjustments by operating on the top handwheel having 0.05 mm
The machine, made from rugged plate, is supplied complete with
control panel, coolant/decantation tank (by water and emulsifying oil),
motor pump, set of abrasive sectors, safety chip guard that when
removed, stops automatically the machine.
The standard supply does not include the locking stirrups and the
diamond sectors (8 pieces) that must be ordered separately
Designed for grinding concrete cube and cylinder
specimens, blocks, natural stones, rocks etc.
