7. Maintenance & Servicing
For a better acknowledgement to this lathe, either in operation or some simple way
of trouble-shooting or servicing, to bring the machine to the utmost function, we are
now stating some important points as below.
7-1 Headstock
1) Prevent from oil leakage from top cover of Headstock:
Before covering the top cover of Headstock, whenever it is removed, please wipe to
clean the contact surface and apply some grease on it. Make sure it is tightly
securing by setscrews.
2) Prevent from blocking up the oil circuit:
The leakage of front headstock cover mostly caused by over-filling the oil or a
block-up of oil circuit. In this moment, remove the Headstock cover first, then blow
the air jet into two oil circuit hole, which is on up side and down side of front
Spindle bearing, in the same time to rotate the Spindle and it will work again.
3) Adjustment on Spindle Bearing:
The front and the intermediate section of spindle roller bearing. For high accuracy
and to meet the request of operation function, you may be asked to adjust the
appropriate pressure on bearing. After a long period of operation, nut “G” probably
will get loose and result the “wave trace” on cutting surface. You need to adjust it at
this moment. Use a hexagon socket wrench to remove the setscrew and install back
with the fixing nut again properly. Only an appropriate pressure is enough. Never
have it too tight, as it will lead to the bearing to over-heated or damage the rolling
surface of bearing and lessen its
dynamics. Make sure to fix the
setscrew completely
after adjustment as
illustrated.
