3-D touch probes
The various HEIDENHAIN 3-D touch probes enable you to:
Quickly and precisely set datums
Measure the workpiece
Measure and inspect tools
The triggering touch probes TS 220 and KT 130
These touch probes are particularly effective for datum setting and
workpiece measurement. The TS 220 and KT 130 touch probes
transmit the triggering signals to the TNC via cable.
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.
