1.1 The TNC 426 B, the TNC 430
HEIDENHAIN TNC controls are workshop-oriented contouring
controls that enable you to program conventional machining
operations right at the machine in an easy-to-use conversational
programming language. They are designed for milling, drilling and
boring machines, as well as for machining centers. The TNC 426 B
can control up to 5 axes; the TNC 430 can control up to 9 axes. You
can also change the angular position of the spindle under program
control.
An integrated hard disk provides storage for as many programs as
you like, even if they were created off-line or by digitizing. For quick
calculations you can call up the on-screen pocket calculator at any
time.
Keyboard and screen layout are clearly arranged in a such way that
the functions are fast and easy to use.
Programming: HEIDENHAIN conversational and ISO formats
HEIDENHAIN conversational programming is an especially easy
method of writing programs. Interactive graphics illustrate the
individual machining steps for programming the contour. If a
production drawing is not dimensioned for NC, the HEIDENHAIN
FK free contour programming carries out the necessary calculations
automatically. Workpiece machining can be graphically simulated
either during or before actual machining. It is also possible to
program in ISO format or DNC mode.
You can also enter and test one program while the TNC is running
another.
Compatibility
The TNC can execute all part programs that were written on
HEIDENHAIN controls TNC 150 B and later.
