General description
Modular design with central unit, monitor and control panel. Display of vertical axis position.
• Control panel with numerical keyboard and screen operation.
• 2 independent programmable axes with the programmable parameters::
o traverse limits
o roughing depth
o Finishing depth
o quantity of excess material
o number of burnout strokes
o Retract position
o Machining depth between dressing passes
o Dressing pass
o Percentage of wheel wear
o Compensation for wheel holder sag
o Compensation for lead screw backlash
• Customized machine control panel, electromagnetic table control, grinding head on/off, mode selection (square, continuous, manual), cross feed adjustment
