New video on YouTube: Pockets/Contours/Drilling operations on 86 program lines with 9 different tools
A new “INSTANT CNC” Video is here!
We have once again simulated a challenging task using our SYMplus™ CNC software – this time, we’re tackling Exercise 7 from the Christiani booklet “Collection of tasks on CNC technology milling according to PAL2020”.
This exercise covers the “full program” to prepare for the test: pockets, contours, drilling operations mixed within 86 program lines using nine different tools.

Throwback 1983 – CNC machines
Time travel to the year 1983! Our founder, Mr. Keller, was working as a vocational school teacher in metal technology at the “Gewerbliche Schule II der Stadt Wuppertal” (now “Berufskolleg Werther Brücke”) in 1983. It was there that the foundations for NC theory and NC practice were laid in the late 70s.
The very first CNC machine at the school was a DECKEL-FP-2-NC milling machine (Refer to the picture). However, back then, there was no money to purchase a lathe machine. But Mr. Keller wasn’t discouraged! He went above and beyond to raise the necessary funds and managed to gather an impressive sum of 140,000 DM (equivalent to 154,216 €, adjusted for inflation) through donations from entrepreneurs in Wuppertal. And thus, the CNC lathe machine, a GILDEMEISTER NEF 400 (The last picture), was acquired.
