3-D touch probes (Touch Probe Functions software
option)
The various HEIDENHAIN 3-D touch probes enable you to:
Automatically align workpieces
Quickly and precisely set datums
Measure the workpiece during program run
Measure and inspect tools
All of the cycle functions (touch probe cycles and
fixed cycles) are described in the Cycle Programming
User’s Manual. Please contact HEIDENHAIN if you

The triggering touch probes TS 220, TS 440, TS 444, TS 640 and
TS 740
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.
TT 140 tool touch probe for tool measurement
The TT 140 is a triggering 3-D touch probe for tool measurement
and inspection. The TNC provides three cycles for this touch probe
with which you can measure the tool length and radius either with
the spindle rotating or stopped. The TT 140 features a particularly
rugged design and a high degree of protection, which make it
insensitive to coolants and swarf. The triggering signal is generated
by a wear-resistant and highly reliable optical switch.
