3-D touch probes
With the various HEIDENHAIN 3-D touch probe systems you can:
„ Automatically align workpieces
„ Quickly and precisely set datums
„ Measure the workpiece during program run
„ Measure and inspect tools
TS 220, TS 640 and TS 440 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 (see figure) and the smaller TS 440 feature infrared
transmission of the triggering signal to the TNC. This makes them
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
control, which stores the current position of the stylus as the actual
value.
All of the touch probe functions are described in the
User’s Manual for Cycles. Please contact HEIDENHAIN if
you require a copy of this User’s Manual. ID: 670 388-xx.
Note that HEIDENHAIN generally does not accept liability
for the function of the touch probe cycles unless you use
HEIDENHAIN touch probes!
