Cycles for milling and turning
HEIDENHAIN controls have always been
known for their comprehensive and
technologically sophisticated package of
cycles. Frequently recurring operations that
comprise several steps are also stored in
the TNC 640 as cycles. You program them
under conversational guidance and are
supported by valuable help graphics that
clearly illustrate the required input parame-
ters. Besides the well known TNC milling
and drilling cycles, the TNC 640 also offers
a wide variety of turning cycles, for example
for roughing, finishing, recessing, thread
turning and recess turning. The field-proven
HEIDENHAIN lathe controls provide the
software basis for the turning functions.
They enable you to very easily program
even complex turning operations at the
machine.
In the more sophisticated contour turning
cycles, the TNC 640 uses the same tech-
niques as are used for milling. Here, too,
there is no need for the TNC programmer
to learn new ways of programming—he
can continue to rely on what he already
knows and quickly find his way into the
world of turning on a milling machine.
