TS 220 and TS 640 touch trigger probes
These touch probes are particularly effective for automatic workpiece
alignment, datum setting and workpiece measurement. The TS 220
transmits the triggering signals to the TNC via cable and is a cost-
effective alternative for applications where digitizing is not frequently
required.
The TS 640 touch probe (see figure) features infrared transmission of
the triggering signal to the control. This makes it highly convenient for
use on machines with automatic tool changers.
Principle of operation: HEIDENHAIN triggering touch probes feature a
wear resisting optical switch that generates an electrical signal as
soon as the stylus is deflected. This signal is transmitted to the TNC,
which stores the current position of the stylus as an actual value.
