Throwback 2004 – Partnership with Haas
“I have seen the future,” wrote Mr. Peter Hall, Managing Director of Haas, almost 20 years ago, on 01/12/2004, in the KELLER guestbook. A special moment that marked the beginning of a longstanding partnership.
The production lines “CNCplus TRAINING” and “CNCplus PRODUCTION” were established shortly thereafter.

Throwback 1986 – R. & S. KELLER GmbH Foundation
Did you know that KELLER didn’t start out as a software company, but as a publishing house?
Under the publisher’s name “R. Keller”, Mrs. Keller first published educational booklets on the topics of CNC machine tools, geometric and technological as well as mathematical basics in 1982. Our SYMplus™ workbooks are still a reminder of this time.
The success of the products finally led to the founding of R. & S. KELLER GmbH by Mr. and Mrs. Keller in 1986. This photo shows the festivities to celebrate the founding of the company.

Throwback 2016 – User Meeting
#ThrowbackThursday to a special milestone at KELLER.Software! Seven years ago, in 2016, our first “KELLER User Meeting” took place.

Throwback 2006 – ZF Friedrichshafen apprentices present SYMplus™ at the METAV
A look back into the year 2006: At the METAV trade fair in Düsseldorf, trainees from ZF Friedrichshafen AG were able to demonstrate their skills at the KELLER booth.
Using the graphical editor of our CNC software SYMplus™, they showed the audience how easy it is to develop a milled workpiece from contour to production. To finish things off, they then milled live on a Haas machine.
Almost 20 years later, SYMplus™ continues to delight with its effortless and time-saving user-friendliness!

Happy Halloween 2023!
We hope you are enjoying the autumn holidays!
On October 31st, some states in Germany celebrate Reformationstag (Reformation day), while others observe November 1st as a holiday (All Saints’ Day). In the state of NRW in Germany (where we are located) we have the latter. Therefore, our office will be closed on Nov. 1st.
No matter which holiday you are celebrating, we wish everyone a Spooktacular Halloween and a relaxed Fall season!

Throwback 1985 – Heidenhain TNC control system KELLER keyboard
Get your floppy disk, V-neck sweater, and shoulder pads ready because on this #ThrowbackThursday, we’re taking you on a journey back to the ’80s.
In the photo, you can see a Nixdorf 8810 M75 Personal Computer with a ‘Color Monitor’ – boasting an impressive 640 KB of storage space! In comparison, today’s home and office computers typically have storage capacities ranging from 256 GB to 1 TB. In fields like video editing and 3D modelling, they can even go up to 4 TB, and there seems to be no limit in sight.
Right in front of this cutting-edge computer from that era, you’ll find a keyboard created by KELLER for the Heidenhain TNC 155 control system used in CNC training. This provided trainees with a 1:1 experience of the original control system and even had a connection to the CNC machine.
