3-D touch probes
If the Touch probe function software option is active, you can use
the various HEIDENHAIN 3-D touch probe systems to:
„ Automatically align workpieces
„ Quickly and precisely set datums
„ Measure the workpiece during program run
„ Measure and inspect tools
TS 220, TS 440 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 may be a
more economical alternative.
The TS 440, TS 444, TS 640 and TS 740 (see figure at right) feature
infrared transmission of the triggering signal. This makes them highly
convenient for use on machines with automatic tool changers.
Principle of operation: HEIDENHAIN triggering touch probes feature a
wear-resistant 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 an actual
value.
All of the touch probe functions are described in a
separate manual. Please contact HEIDENHAIN if you
require a copy of this User’s Manual. ID 661 891-10.
