Mastering Sinumerik CYCLE88 Bore 4: Dwell Time & Spindle Stop Operations
Sinumerik CYCLE88 Bore 4
In Sinumerik CYCLE88 “Bore 4” cycle, a dwell time is effected on reaching the final drilling depth together with a spindle stop without orientation and a programmed stop. By pressing the NC Start key, the upwards movement is performed at rapid traverse until the retraction plane is reached.
