If you do not have the right equipment or sufficient capacity to machine your components in-house, have SMB Schwermechanik GmbH do the machining for you. Our customers always receive best quality, as we machine the components with highest precision and to highest quality standards on the basis of drawings, specifications or standards provided by the customer.

Production process

Whether contract CNC machining, such as milling and turning, or drilling: we machine individual raw parts or semi-finished components provided by our customers, or source forgings or castings produced within GMH Gruppe for our customers, which we then machine on a toll basis as specified by the customer – finish- or semi-finish-machined by milling, turning and/or drilling.


Our customers benefit from optimally harmonized single-source processes, modern equipment and service expertise: we cover the complete value chain from the customer’s initial enquiry up to and including final acceptance. Customers contracting SMB Schwermechanik GmbH for the machining of their products benefit from our decades of expertise and our highly flexible process management, which enable us to machine even one-offs and small batches extremely cost-efficiently and in the shortest possible times.
