The term adjustment refers to all the surface finishing phases that are generally carried out at the end of the production cycle, in order to guarantee the compliance of the details in terms of surface roughness, and in terms of aesthetics and functionality. Considering the wide range of geometries that OM4 can produce, the pieces are adjusted manually by highly specialized staff, equipped with the necessary instrumentation, simple but suitable for the purpose: rotating brushes, files, abrasive cloths of various weight, bench grinding, sanders and manual grinders, tumbling plants. In this phase the quality of the surfaces produced is constantly monitored to ensure compliance with the requirements, like for example the absence of processing burrs and sharp edges, which are not accepted by the majority of applications.
