3-D touch probes (Touch Probe Function 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

TS 220, TS 440, TS 444, TS 640 und TS 740 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.
TT 140 tool touch probe for tool measurement
The TT 140 is a triggering 3-D touch probe for tool measurement
and inspection. Your TNC provides three cycles for this touch
probe with which you can measure the tool length and radius
automatically 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.
