Function
The 3-stage surface grinding cycle allows you to machine a surface that is wider than the
wheel itself. The surface concerned is ground using the oscillation method/intermittently.
Y infeed takes place at the X and Z reversal points (left/rear, right/rear, left/front or
right/front).
Intermediate dressing, interruption and use of the handwheel are all supported.
The keys will only ever respond at the end point.
At the end, the tool retracts to the starting position.
A higher infeed amount can be used at the start of machining.
Once contact has been detected using an acoustic emission sensor, the tool will retract by
the acoustic emission sensor infeed amount minus the grinding infeed amount.
If no acoustic emission sensor input has been configured, the cycle will immediately switch
to the handwheel at the start of the operation.
