are very precise systems that can only be maintained and installed by specialists. To work with a profile grinder
, one should be a qualified milling-machining mechanic or machine fitter. Profile grinders are metal cutting machines
and must be enclosed, and secured against unauthorised access. Support staff can only be hired to assemble and transport the finished products. Despite the high quality of production of the available profile grinders
, depending on the manufactured products, disturbances and failures are possible. Therefore, there should be a qualified and knowledgeable specialist in the close vicinity of the profile grinder at all times.
