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.

Visit from China, Jining University
Last Friday, we had the pleasure of welcoming a delegation from Jining University in the Shandong province of China, led by University President Wang Qingming, here in Wuppertal.
The ‘School of Industry’ with whom we’ve already signed a letter of intent for the purchase of a SYMplus™ licence in China, was represented by Dr. Zhou Ke, the Director of the CNC department. After a delightful exchange of tea and gifts (including a book made of precious silk), they continued their journey to visit our friends at BZI Remscheid.

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!
