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 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 is a cost-
effective alternative for applications where digitizing is not frequently
required.
The TS 640 touch probe features infrared transmission of the
triggering signal to the control. This makes it 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 TNC,
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. Nr.: 533 189-xx.
