A workpiece set-up and inspection probe is in effect another
tool in the system. A probe cycle may be included at any
stage of the machining process.
Signals are transmitted between the probe and the machine
control, via the OMP and OMM + MI 12 or alternatively the
OMP and OMI.

OMM TANDEM MOUNTING
Installations with exceptionally long
spindle travel, may require a
second OMM to cover signal
reception over the full working
envelope of the probe.
The reception cones of OMM 1
and OMM 2 overlap, so they
act as one receiver.
REMOTE INDICATOR
When the probe contacts a surface
an MI 12 LED changes state and a
bleep is emitted.
If the MI 12 is hidden from the
operator, a remote lamp or bleeper
may be placed in a position where
it is easily seen or heard.
OMM TWIN MOUNTING
Each spindle of a twin
spindle machine can
accept a probe.
Although both OMM 1
and OMM 2 are
switched on, only one
probe may be used at
any one time.
