Scope

This part specifies the tolerances for the inspection of the positioning accuracy of the linear axis and the rotary axis of the precision machining center. This section applies to precision machining centers with linear axis strokes up to 2 000 mm and rotary axis strokes up to 360°. Precision machining centers with a linear axis stroke greater than 2 000 mm can also be used as a reference.
