1) Warm up machine, espec ially the spindle and lubrication pump by running the m
for 10 to 20 minutes at about half or one -third the maximum speed in dicated on the
manual.
2) This self-warming -up program should activate each machine’s component t o
operate. At the same time please check their operations’ correctness.
3) Be particularly careful to warming u p the spindle, which can turn up to 45 00rpm.
If the machine is used for actual machining immediately after spindle start,
following a long idle p eriod, sliding parts such as bearings may be worn due to lack
of lubrication oil. Also, thermal expansion of the machine’s components can
jeopardize machining accuracy. To prevent this from happening, always warm the
machine up.
