Orders up to the end of the year will still be processed at the previous conditions.
There are … Insights into the examination task for cutting machine operators
The IHK examinations for cutting machine operators took place on December 6. We used SYMplus to simulate the examination task for CNC milling. You can watch the video on our YouTube channel. (Turning video will come in the following days. Keep yourself subscribed to get updates)
Merry Christmas and a successful start to the New Year
Finally, we would like to wish you and your families a Merry Christmas and a good start to the New Year.

Merry St. Nicholas’ Day!
In Germany, it is a tradition to place polished boots outside the door on the evening of December 5th. According to legend, St. Nicholas then comes by during the night and fills your boots with sweets and small gifts. 🍬
We may not have sweets for you, but we’ve got a new, interesting video on our YouTube channel!
Watch how we simulated the St. Nicholas’ house with our SYMplus™ CNC software in four different ways:
- G17 IP3 – End face machining with virtual Y-axis
- G17 IP5 – End face machining with real Y-axis
- G19 IP1 – Surface machining with virtual Y-axis
- G19 IP5 – Chord surface machining with real Y-axis
