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

■

Digitize 3-D surfaces (option), and

■

Measure and inspect tools

TS 220 and TS 630 touch trigger probes
These touch probes are particularly effective for automatic
workpiece alignment, datum setting, workpiece measurement and
for digitizing. 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 630 features infrared transmission of the triggering signal to
the TNC. 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.

During digitizing the TNC generates a program containing straight
line blocks in HEIDENHAIN format from a series of measured
position data. You can then output the program to a PC for further
processing with the SUSA evaluation software. This evaluation
software enables you to calculate male/female transformations or
correct the program to account for special tool shapes and radii that
differ from the shape of the stylus tip. If the tool has the same
radius as the stylus tip you can run these programs immediately.

TT 120 tool touch probe for tool measurement
The TT 120 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 120 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.

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.
