Efficient Tapping with Sinumerik CYCLE840 and Floating Tapholder – No Encoder Needed

Sinumerik CYCLE840 Tapping with Floating Tapholder

With Sinumerik CYCLE840 cycle, tapped holes can be produced with floating tapholder

For tapping without floating tapholder (rigid taping) CYCLE84 is used.

CYCLE840 (RTP, RFP, SDIS, DP, DPR, DTB, SDR, SDAC, ENC, MPIT, PIT)

Parameter	Description
RTP	Return plane (absolute)
RFP	Reference plane (absolute)
SDIS	Safety distance (enter without sign)
DP	Final drilling depth/elongated hole depth/slot depth/pocket depth (absolute)
DPR	Final drilling depth/elongated hole depth/slot depth/pocket depth relative to reference plane (enter without sign)
DTB	Dwell time at final drilling depth (chip breaking)
SDR	Direction of rotation for return Values: 0 (automatic reversal of direction of rotation) 3 or 4 (for M3 or M4)
SDAC	Direction of rotation after end of cycle Values: 3, 4 or 5
ENC	Tapping with/without encoder Values: 0 = with encoder 1 = without encoder
MPIT	Thread pitch as thread size – 3 (for M3) … 48 (for M48)
PIT	Thread pitch; values: 0.001 … 2000.000 mm
