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
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 and TS 640 (see figures at right) 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 TNC,
which stores the current position of the stylus as an actual value.
HR electronic handwheels
Electronic handwheels facilitate moving the axis slides precisely by
hand. A wide range of traverses per handwheel revolution is available.
Apart from the HR 130 and HR 150 integral handwheels,
HEIDENHAIN also offers the HR 410 portable handwheel.
