CNC service from Weyerbusch for OKUMA and NEXTURN.
We repair, maintain and sell OKUMA and NEXTURN machines and supply spare parts throughout Germany and Europe.
A family business with its own workshop
Schirmer GmbH has specialized in spare parts and repairs for CNC machines for over 20 years. We know the technology, because we repair it ourselves.
Our workshop in Weyerbusch is where we restore boards, control units and drives piece by piece. Every repair is documented, every part is tested before shipping.
You have one fixed contact person with us, from the first call to the return shipment.
