3D touch probe systems
The TNC provides the following features when
used in conjunction with a 3D touch probe:
.-
l Automatic workpiece alignment (i.e. compensa-
tion of workpiece misalignment)
l Datum setting
l Measurement of the workpiece during program
run
l Digitizing 3D surfaces (option)
l Tool measurement with the lT 120 touch probe
The TS 220 transmits signals via cable, the
TS 630 via infrared light.

Floppy disk unit
The HEIDENHAIN FE 401 floppy disk unit serves
as external memory for the TNC, enabling you to
store programs and tables on diskette.
With the FE 401, you can transfer programs that
were written on a PC to the TNC. Very large
programs that exceed the storage capacity of the
TNC can be “drip fed” block-by-block: The ma-
chine executes the transferred blocks and erases
them immediately, freeing memory for further
blocks from the FE.

The electronic handwheels give you manual
control of the axis slides. Similar to a conventional
machine tool, the machine slide moves in direct
relation to the rotation of the handwheel. The
traverse distance per handwheel revolution can be
adjusted over a wide range.
