The TNC7 controls on the two machines ensure perfect machining processes. Tobias Grötzinger says the high-resolution simulation graphics are one of the highlights of the TNC7. Before he executes any NC programs on the machine, he always runs them through the control's simulation even though the programs from the design department were already simulated in the CAM system. "Only this way can I be sure that really all machine parameters are taken into account. And the extended possibilities of the TNC7 and simple touchscreen operation provide me with such deep insights that I really can check each detail in advance." If the control's simulation shows Tobias Grötzinger any possibilities for optimization, he reports them to the design department: "We don't make any changes at the control. We do that in the CAM system to ensure data consistency."

One of the main tasks of the day-shift specialists is proving-out new job orders on the machine, including measuring all workpiece blanks. This preparatory work ensures that the late-shift and night-shift colleagues can concentrate on filling the pallet system with workpieces for subsequent orders.

Tobias Grötzinger still performs these measurements manually with a handwheel and the TS 460 touch probe from HEIDENHAIN. But the automated cycles of the TNC7 assist him during workpiece setup.

The TNC7 makes not only job preparation very easy, but also the insertion of new tools. Tobias Grötzinger explains, "We insert new tools manually. The TNC7 makes it so easy to enter the data that we don't need an automated workflow." And here's something else the metal cutting mechanic really likes about his daily work with the new control: "Even with all the precaution we take, every so often a tool breaks. I can find the affected tool in the new tool tables of the TNC7 in a flash and then quickly exchange it in tool magazine."

The team at CNC-Technik Mack also considers the fact that each mechanic can adjust the user interface as desired to be a big advantage of the TNC7. "When I log on to the control, I immediately see what I expect, no matter who used the machine last," is how Tobias Grötzinger expresses his appreciation of this individual adaptability. "I can almost operate the TNC7 without even looking at the screen, since everything is always exactly where it's supposed to be." That's because nobody needs to search for any operating elements or menu windows that some other colleague didn't need and then closed.
