According to DIN 31051 maintenance is defined as "combination of all technical and administrative measures as well as the management measures during the life-cycle of the object being considered, required to maintain its fully functional condition or to return it to this condition so that it can perform the required function".
Spindle maintenance includes servicing, inspection, repair and improvement. When devising maintenance, consideration is given to the internal and external requirements of the company, as well as the repair strategies, and repair objectives are tailored to the objectives of the company.
Spindle maintenance is often offered under spindle servicing as a service. This encompasses, for example, the removal and installation of the spindle, checking and optimisation of the bearings, repair of the spindles or balancing of the spindle unit.
