Used to grind and polish rock and concrete specimens, natural stones, ceramic materials, etc.  Proposed in two versions:

  • Standard version in which the radial displacement of the grinding head is motor operated and actuated by a push button.
  • Automatic version in which the radial displacement is fully automatic and controlled by travel limit switches.

All the other specifications are the same.

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. This means that the only manual operation required is the lowering of the grinding head by the top hand wheel. The machine is supplied complete with safety chip guard that, when removed, automatically stops the machine. The standard configuration also includes the 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 the device for dry grinding operations are also available on request (see accessories). The Core face preparation jig can be easily fitted by the clamping element supplied with the machine.
