The origin of our company goes back into the 1990s.
At that time, then company founder Josef Reinauer worked for a renowned tool manufacturer from our region and was occupied with the development of innovative HSK clamping systems. Based on his inventions at that time, some of which were patented worldwide, the HSK tool–machine interface, introduced and standardised around the world today, came into being with his collaboration in a wide variety of work groups in cooperation with RWTH Aachen.
The independent development of HSK clamping systems for the HSK interface then led to the foundation of SiGMA GmbH in 2002.
Our product range now includes automatic clamping fixtures from HSK-20 to HSK-160, manual HSK clamping fixtures from HSK-20 to HSK-160, as well as automatic & manual SK clamping systems. SiGMA is your competent contact when it comes to solutions in the field of toolholding technology. Years of experience and courage to pursue new paths are the most valuable approaches to new solutions – that is the philosophy of our young and successful company.
