7.10 Grinding spindle drive with a second speed range up to
206,7 ft/s (optional)
The second speed range for cutting speeds of up to 206,7 ft/s is only possible in
automatic mode. The maximum cutting speed in setting-up mode and semi-auto-
matic mode is 114,83 ft/s.
7.10.1 Changing the speed
The higher cutting speed in the second speed range (up to 206,7 ft/s)
also means an increased risk of accidents as a result of grinding
wheels bursting apart or workpieces flying off the clamping system.
Always use grinding wheels that are approved by the manufacturer
for these cutting speeds and identified accordingly. Make sure that
your workpieces are properly clamped and secured.
When you change the speed range, no programs are allowed to be
active and the grinding spindle drive must be switched off.
To change the speed range, reset the position of
key switch 1-S6 from 0 = max. 114,83 ft/s to 1 =
max. 206,7 ft/s. This switch is located on the rear
of the control cubicle underneath the master
switch and key switch 8-S4 (grinding without a ma-
gnet).
If you attempt to program a cutting speed of more
than 114,83 ft/s when key switch 1-S6 is set to 0,
the following message will be displayed: "700050
Cutting speed too high ??".
Do you really want to cut at this high speed and
are all the conditions for doing so satisfied?
If so, set key switch 1-S6 to 1, and acknowledge
the error message. You can now cut at the selec-
ted high speed in automatic mode.
