2.3 Programming notes
The transmission ratio of the Speedsynchro
®
Mini is 1:4,412.
This results in the following programming guidelines.
Feed f
Rotational speed n
of the
machine spindle
for the desired tool speed
Attention
The maximum speed at the machine spindle is: n
MSP
= 2.700 rpm
The maximum speed at the tool is: n
TOOL
= 11.912 rpm
Example: thread M2 / pitch P = 0,4 mm:
Desired rotational speed of threading tool:
n
TOOL
= 11.000 rpm
Required rotational speed of machine spindle:
n
MSP
= 11.000 rpm / 4,412 = 2.490 rpm
Required feed f, per revolution of the machine spindle:
f = 0,4 x 4,412 mm/
rev.
=
1,765
mm/
rev.
Der Speedsynchro
®
Mini is ready for use.
Attention
When working with internal coolant supply:
The maximum coolant-lubricant pressure is
70 bar
.
The internal coolant is supplied centrally through the spindle.
