Tin in CNC systems is on the EU critical materials list. Gold, palladium and tin create a high supply risk in CNC systems, concentrated in ICT components; tin is on the EU list of critical materials. The manufacturing study for Overijssel by New Economy (2020) reports this for CNC systems. CNC systems retain much component value after depreciation, which is lost without a circular model.
An operating and performance model keeps CNC systems in use longer and more valuable. This is relevant for manufacturers of CNC systems, machine builders and organisations in circular manufacturing.
