  • To grind concrete specimens, natural stones, tiles, block pavers, ceramic materials etc.
  • Large base table for grinding contemporaneously up to three 100 mm cubes, or three 150 mm cubes, or two 200 mm cubes and concrete/tile blocks of various sizes (see drawing of working area).
  • For cylinders up to dia. 160x320 mm
  • Motorized radial displacement in both directions by pushbutton or totally automatic with the 55-C0201/C version
  • Safety guard with door locking switch conforming to CE
  • Complete with clamping elements for cubes
  • Suitable for dry grinding procedure. See accessories
  • Diamond impregnated sectors available as alternative to abrasive
  • Ideal for surface preparation of rock samples using the accessory 45-D0534/B and 45-D0534/C
General description
General description
Used to grind and polish concrete specimens, natural stones, ceramic materials, etc.  Proposed in two versions:
  • 55-C0201/B standard version in which the radial displacement of the grinding head is motor operated and actuated by a push button.
  • 55-C0201/C Automatic version in which the radial displacement is fully automatic and controlled by travel limit switches.
All the other characteristics are identical.
The cube and cylinder specimens can be easily locked on the table and the grinding head, 330 mm dia., can be radially moved either manually or automatically in both directions so, the only manual operation requested is the lowering of the grinding head by the top hand wheel. The machine is supplied complete with safety chip guard that, when removed, stop automatically the machine, with coolant tank, motor pump and one set of abrasive sectors. Diamond grinding sectors are available on request (see accessories). The machine is supplied complete with clamping element for 100, 150 and 200 mm cubes. Clamping devices for cylinders and device for dry grinding procedure are also available on request (see accessories). The 45-D0534/B and 45-D0534/C  Core face preparation jigs can be easily fitted by the clamping element supplied with the machine.
