Sinumerik CYCLE87 Bore 3: Precision Spindle Stop & Rapid Retract
Sinumerik CYCLE87 Bore 3
In Sinumerik CYCLE87 “Bore 3” cycle, a spindle stop without orientation is effected on reaching the final drilling depth, followed by a programmed stop. By pressing the NC Start key, the upwards movement is continued at rapid traverse until the retraction plane is reached.
