3 Getting started
3.1 Device description
LaboForce-50 is a control panel/specimen mover unit which can be mounted on the following
machines for semi-automatic materialographic preparation (grinding/polishing): LaboPol-20,
LaboPol-30 and LaboPol-60.
The operator selects the grinding/polishing surface and the cooling fluid/abrasive suspension to
be applied.
A holding device for the preparation of specimens must be used with the specimen mover. The
holding device holds 4 specimens.
3 Getting started
LaboForce-50 7
The specimen mover head has pressurized feet which can be adjusted individually to keep the
specimens in place.
The operator decides which holding device should be used and the specimen force is adjusted
individually on the pressurized feet from the mover head to keep the specimens in place.
The operator sets the rotation speed of the preparation disc before starting the process.
The operator starts the machine by pressing the Start button on the control panel.
Cooling water is applied automatically when the operator opens the water tap. The operator applies
other fluids manually or by using a separate dosing unit.
The operator stops the machine by pressing the Stop button on the control panel.
The operator cleans the specimens before the next preparation step or inspection.
The machine must always be used with the splash guard in place.
If the emergency stop is activated, the power to all moving parts is cut.
