MAINTENANCE & ADJUSTMENT
Please refer to following items for machine problems and its solution. And also
ask users to maintain the lathe the best way, thus prolonging the service life of it.
7-1 Headstock
1.
To avoid the headstock cover oil leaking: Once the headstock cover is opened, please use cloth
to clean the matching surfaces and apply some grease, then you can close the cover and tighten
the screws again.
2.
To avoid the returning oil route being blocked: There are two reasons which cause the oil
leaking from headstock front cover; one is over filled; the other is that the returning oil line is
blocked. Customer should take off the headstock cover. Then blow air to the small hole, which
is on the top of the front bearing, by air gun several times. And rotate the spindle at the same
time to clean up the blocked returning oil line.
3.
Spindle bearing adjustment: The front and middle bearings of the spindle is precision taper
roller type. It is specified to require the bearings to have suitable preload for maintaining
the high accuracy and the best rotating functions. After long usage, the locking nut G may be
loose a little bit and result in chattered cutting finish. For adjustment, loosen the set screw by
allen wrench. Then tighten the locking nut G to obtain the suitable preload. Do not over-tighten
as too much preload will make the bearings hot; damage the rotating surface of the bearings
and slowing down the bearing motions. After adjustment, please be sure to tighten the locking
screw completely.
