TNC 320 - TNC 640 - DR. JOHANNES HEIDENHAIN GmbH

Workpiece measurement and automatic
compensation of tool data
Together with the TT 140 touch probe for
tool measurement (see page 25) the
TNC 320 can automatically measure tools
while they are in the machine. The TNC 320
saves the ascertained values of tool length
and radius in the central tool fi le. By
inspecting the tool during machining you
can quickly and directly measure wear or
breakage to prevent scrap or rework. If
the measured deviations lie outside the
tolerances, or if the monitored life of the
tool is exceeded, the TNC 320 locks the
tool and automatically inserts a
replacement tool.

Tool management
For machining centers with automatic tool
changers, the TNC 320 offers a central tool
memory for any number of tools. The tool
memory is a freely confi gurable fi le and
can therefore be optimally fi tted to your
needs. You can even have the TNC 320
manage your tool names. The control
prepares the next tool change while the
current tool is still cutting. This signifi cantly
reduces the non-cutting time required for
changing tools.
