Spindle improvement

DIN 31051 defines improvement as a "combination of all technical and administrative measures as well as the management measures required to increase functional reliability of the unit under consideration, without changing its required function".
Similarly to the repair procedure, the improvement procedure encompasses "calculations, schedule planning, customising, provision of personnel, equipment and materials, creation of work plans" and the implementation of the improvement.   After the improvement measures have been implemented, a renewed functional check is essential to assure the correct functionality.
The area of spindle improvement encompasses, for example, the conversion from steel balls to ceramic balls in spindle bearings in order to increase the rotational speed or the conversion to minimum quantity lubrication.
