−
Use appropriate clamping devices to fasten the workpieces to
the machine table.
Tip: Bridging for nesting applications
When nesting is being carried out, it is recommended to leave
material bridges between smaller components. As otherwise the
final edge of the loose workpiece will be routed and this can lead
to dimensional deviations.
Tip: Cleanliness in the workplace
Shavings and dust on the machine table have a negative influ-
ence on the end result. Clean the machine table before loading
the workpiece.
Warm up the HF-spindle before use, if
●
ambient temperature is below 17°C.
●
for new HF-spindles daily for the first 5 days.
●
HF spindle has not been in operation for more than one month.
1.
Start machine.
2.
Warm up the HF spindle for 5 minutes in idle mode at 12,000 rpm.
�� The machine is ready to operate.
If the workpiece is bowed, then clamp it with the bow facing upwards. If locking
holes are drilled for groove nuts, then they have to be chosen in such a way, that
the bow will be optimally compensated against.
