Operation
The operation and surface grinding can be done manually or NC controlled.
In manual surface grinding, the grinding wheel is infeeded after each surface grinding pass via
a servo motor using the electronic handwheel, or via pushbuttons on the control panel in jog
mode. The oscillation distance of the table to the left and to the right is set by adjustable end
stops, which cause the hydraulic cylinder to reverse the direction via the hydraulic hand lever
valve. The speed of this oscillation is infinitely adjustable with this hand lever valve. The oscilla-
tion is only possible if the electromagnet on the grinding table has been switched on before-
hand. The speed of the transverse movement in the transverse axis is infinitely variable via a
controller on the operating panel. The corresponding distance with return path in the trans-
verse axis to the rear and to the front is set via trip cams.
In NC-controlled operation, the grinding wheel is automatically infeeded after each surface
grinding pass in the Y axis according to the entered number of infeeds. The <HMI> (Human
Machine Interface) is a touch panel for entering the number of infeeds in the NC control and for
displaying information.

The surface grinding machine must only be operated under the following conditions:
The surface grinding machine is in proper working order.
The surface grinding machine is used as intended.
The operating instructions are observed.
All safety devices are installed and activated.
Eliminate or have all malfunctions rectified promptly. In the event of malfunctions, shut down
the surface grinding machine immediately and secure it against unintentional or unauthorised
commissioning. Notify the person responsible immediately of any modification.
