CAUTION
1) Check lubrication gauge for proper reading (only for 6VK).
2) Check spindle, coolant motor (only for 6VK), powerfeeds (only for 6VK) and
other parts for abnormal noises.
3) Check the motor lubrication and sliding parts for evidence of proper lubrication.
4) Check safety covers and safety devices for proper operation (optional
accessories).
2) Check belt tension. Replace any belt that has become stretched with a fresh
matching belt.
1-4-3. Warm-up
1) Warm up machine, especially the spindle and lubrication pump by running them
for 10 to 20 minutes at about half or one-third the maximum speed indicated 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 up the spindle, which can turn up to 4500rpm.
If the machine is used for actual machining immediately after spindle start,
following a long idle period, 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.
1-4-4. Preparations
WARNING
1) Tooling should conform to the machine specification and dimensions’ types.
2) Seriously worn-out tools can cause injuries. Replace all such tools with new
ones before intended operation.
3) The work area should be adequately lighted to allow for safety checks.
4) Tools and other items around the machine or equipment should be stored to
ensure good footing and clear aisles.
5) Tools or any items must not be place on the head housing, table, ram and other
similar places.
CAUTION
1) Tool lengths should be within specified tolerances to prevent interference.
2) After installing a new tool, please make a trial cut.
