Does your workpiece, after complex milling
operations, also need to be set up on a
lathe for several working steps? Do you
have to plan for machine capacity, make
tools, set up and fix the workpiece, and
measure the finished part? Here the TNC
640 helps you to save a great deal of time:
On a milling turning machine with the TNC
640, you machine the workpiece from a
single casting: milling, turning, milling, in
whatever sequence. After performing all
operations on one machine, you measure
the finished workpiece with a HEIDENHAIN
touch probe.
Multi-operation machining
– Milling and turning on one machine (option)
The TNC 640 offers you powerful functions
that enable you to switch the NC program
as desired between turning and milling
under program control. This enables you to
decide with complete freedom how and
when you want to combine the two
machining methods. And of course, the
operations switch back and forth regardless
of the machine and its axis configuration.
During switchover, the TNC 640 assumes
all necessary internal changes, such as
switching to diameter display, setting the
datum in the center of the rotary table, and
even machine-dependent functions such as
clamping the tool spindle.*
Programming as accustomed
You can program the turning operations—
as always—conveniently under dialog
guidance in HEIDENHAIN plain language.
Besides the standard path functions you
can also use FK free contour programming
to easily create contour elements not
otherwise dimensioned for NC. Beyond
this, you also have the contour elements
recessing and undercutting for turning
operations, which are supported by
expressive help illustrations.
If a contour exists in DXF format, you can
easily import it with the aid of the DXF
converters (option).
* The machine must be prepared by the machine tool
builder for this function.
