Machine bed
Equipped with a machine bed made of “MICRO-GRANIT”.
The torsion-resistant machine bed impresses with its excellent damping properties (around 10:1 compared to gray cast iron) and very good thermal stability.
Table drive via toothed belt
Advantages of toothed belt drive to hydraulic table drive:
“Low maintenance – stays cold – quiet”
Machines from the Super-Rubin series are universally applicable
surface grinding machines that, thanks to their table drive via toothed belt, can be used perfectly
for both conventional pendulum grinding work and short-stroke pendulum grinding .
The table drive is characterized by its extremely quiet running and eliminates the
noises associated with the hydraulic pump.
This table drive eliminates the heat development that is inevitably present in hydraulic machines. The machine remains cold and therefore has a “positive” influence on the machine geometry, even over continuous use.
GRINDING PROGRAM NK
The NK grinding program enables the quick and optimal processing of workpieces with different machining dimensions. Depending on the workpiece to be processed, you can choose between a surface and plunge grinding cycle. An attached measuring system with 0.001 measuring accuracy records the grinding wheel infeed and controls the automatic grinding cycle with its subsequent electronics. This consists of different adjustable feed sizes for the grinding wheel.
Switching off the infeed when the target size of the workpiece has been reached, adjustable firing time, return of the disc and the machine table to the starting position.
The dressing amount of the grinding wheel is automatically compensated and displayed on the digital display of the Y-axis. The wheel wear caused by grinding is compensated for during dressing. The size of the processing feeds and the oscillation speed of the table can be adjusted to 15 levels on the control panel.
Roughing amounts: 0.002-0.03 mm
Finishing amounts: 0.001-0.015 mm
Firing strokes: 0 - 15
Lifting amount: optionally 0 - 3.0 mm or back to starting position
Micro handwheel: switchable for the Y or Z axis
