Milestones in the company history
For decades the name KELLER has been inseparably connected with the development of CNC solutions and the education and training of CNC users.
1984First Software
The publishing house R. Keller offered the first software “ Introduction to CNC technology without fear ” for basic CNC training. It was developed by the vocational school teachers Mr. Keller and Mr. Grossmann.

1985EPL1-Simulator
The grammar school teacher Mr Werner Buhr developed the EPL1 simulator on Apple Ile. To the EPL1 keyboard were later added the DOS computers and many other keyboards, resulting in the 3-stage model of a CNC training.

1988First partnerships
The product GKE + CAM sold like hot cakes and attracted a lot of attention. The product was also well received by the Siemens company. A partnership with Siemens was established.

1990Technology Centre
The KELLER Technology Centre was ceremonially opened. The heart of the technical centre is the workshop with 6 CNC machines and 6 different CNC controls.

1995CAMplus und Qplus
The successors of CNCplus are CAMplus for production and Qplus for qualification.

1999Multimedia learning systems
Cooperation with SIEMENS to develop interactive, multimedia learning systems.

2001KELLER software for Young and Old
Our software is not only fun for young people, but also for older skilled workers. Especially those who have so far “only” worked on conventional machines and are now no longer “afraid” of CNC.

2003Four levels of education
Starting with version 3.0 there are 4 levels of education: Workshop, DIN/PAL, Control and CAD/CAM. These can still be found in our products today.

2010Partnership with Heidenhain
At a big meeting here in Wuppertal the HIT project was decided. But before that there was already a KELLER-Heidenhain multimedia version created at own expense.

2011CNC KELLER GmbH
The Keller couple withdraws from the business of the company. The CNC KELLER GmbH is founded.
