Plunge grinding NC sequence program
CAUTION!
Risk of breaking the grinding wheel!
The transverse axis feed in automated plunge grinding is switched off. An adjustment in
the transverse axis must not be made with the handwheel.
There is only infeed of the grinding wheel in the Y axis.
The automatic downward feed of the grinding wheel can be activated by at least one rough
grinding number if the fine grinding number is not set to 0.
The function "Infeed on one side only" or "Infeed of the grinding wheel on both sides" after each
oscillating movement can be selected in the <HMI>. This function can only be used for plunge
grinding.
After completion of the entered sequence steps, "sparking" occurs without infeed of the grinding
wheel. The grinding head is then raised and the hydraulic pump is switched off to stop the oscil-
lating movement of the table.
The NC sequence program for plunge grinding is started by setting the
operating mode selector switch <SA4> to <automatic <HMI>
Press push button <SB6> to start the sequence program.

the master switch.
