1 Introduction
TNC Accessories
3D Probe Systems
The TNC features the following functions for the
HEIDENHAIN 3D touch probe systems:
• Automatic workpiece alignment (compensation
of workpiece misalignment)
• Datum setting
• Measurements of the workpiece can be per-
formed during program run
• Digitizing 3D forms (optional)
The TS 120 touch probe system is connected to the
control via cable, while the TS 510 communicates
by means of infrared light.
Floppy Disk Unit
The HEIDENHAIN FE 401 floppy disk unit serves as
an external memory for the TNC, allowing you to
store your programs externally on diskette.
The FE 401 can also be used to transfer programs
that were written on a PC into the TNC. Extremely
long programs which exceed the TNC's memory
capacity are “drip fed” block by block. The machine
executes the transferred blocks and erases them
immediately, freeing memory for further blocks
from the FE.
Electronic Handwheels
Electronic handwheels provide precise manual
control of the axis slides. As on conventional
machines, turning the handwheel moves the axis
by a defined amount. The traverse distance per
revolution of the handwheel can be adjusted over a
wide range.
Portable handwheels, such as the HR 330, are
connected to the TNC by cable. Built-in hand-
wheels, such as the HR 130, are built into the
machine operating panel.
An adapter allows up to three handwheels to be
connected simultaneously. Your machine manufac-
turer can tell you more about the handwheel
configuration of your machine.
