Operating instruction edition: 01.09.2022 13
2.3 Programming notes
The transmission ratio of the Speedsynchro
®
Modular/NFC is
1:4,412
.
This results in the following programming guidelines.
Feed f
f = Feed [mm/
rev.
]
P = Pitch of threading tool [mm]
Rotational speed n
of the
machine spindle
for the desired tool speed
n
MSP
= Rotational speed of machine spindle [rpm]
n
TOOL
= Rotational speed of threading tool [rpm]
Attention
The max. speed at the machine spindle is: n
MSP
= 2000 rpm
The max. speed at the tool is: n
WZG
= 8824 rpm
Example: thread M6 / pitch P = 1 mm:
Desired rotational speed of threading tool:
n
TOOL
= 6000 rpm
Required rotational speed of the machine spindle:
n
MSP
= 6000 rpm / 4,412 = 1360 rpm
Required feed:
f = 1 x 4,412 mm/
rev.
=
4,412
mm/
rev.
n
MSP
= n
TOOL
/ 4,412
f = P x 4,412
