Our Success Story

What began in a garage quickly turned into a success story: Before founding the company, the two managing directors, Sascha John and Jens Korndörfer, worked together at a contract manufacturing firm—Mr. John headed up purchasing, while Mr. Korndörfer developed the quality management system. When the company was sold, it was clear to both of them: Now was the right time to take the next step. With their many years of experience, industry knowledge, and a strong network, they founded J&K CNC Technik GmbH in October 2018.

Today, we are a sought-after trading partner for CNC-machined custom parts and have grown into an established, family-run company. Centrally located in Europe, we currently employ 18 people at our Bingen site in the Rhine-Main region.
