Two slides work simultaneously
„ In a first roughing operation the workpiece is machined to the point
at which it can be recess turned.
„ The recessing (N26 to N34) is conducted parallel to further roughing
operations (N20 to N25)
Slide 1 defines the cutting speed. For this reason it is
moved after the roughing operation to a parking position
that allows an adequate cutting speed.
