If you need to replace an existing machine knife but don’t have drawings or part numbers, Murbek Engineering can help.
We provide reverse engineering and blade copying from an existing blade sample or from drawings/spec sheets.
Reverse engineering is taking a machine knife/blade and creating the information needed to reproduce it accurately. This usually consists of key dimensions, mounting details, edge geometry and functional features.
Blade copying is ideal when:
