/// THE OPERATING CONCEPT The new multifunction handwheel makes work significantly easier and faster. The axes are selected and controlled by only one module to avoid the possibility of incorrect operation. The handwheel is also used as a potentiometer in order to carry out speed adjustments in automatic mode. /// Different grinding speeds can be entered depending on requirements: Optimised machining time or maximum surface quality /// No need for manual adjustment of radial and tangential clearance angles – which means that operating errors are avoided. Values can be entered as angles or absolute...
