Handle 5, Handle 9 are both for locking drill-mill head-stock. When they
are loosened, the drill-mill head stock can rotate 360
°
around the column,
or the drill-mill head stock can move vertically by using elevator handle
(accessory) to rotate the gear shaft 11.
When the drill-mill spindle is working, the handles must be locked tightly.
●
Handle 17 is used to lock drill-mill spindle quill. When handle 17 is
loosened and handle 15 is pushed in, you can do drilling work by
operating handle 14. When milling, handle 17 must be locked and the
drawing bar must be set to draw the taper shank, which is mounted in the
spindle. Knob 16 is a micro-feed control knob, which is used to control
the milling depth. Cone knob 15 must be pulled out before the micro
control, but when the milling depth has been controlled, it must be pushed
in to mill.
●
Two electric switches, one for turning operation and the other for
drilling-milling operation, can not be operated simultaneously. Only one
of which can be started for working. Otherwise dangers may occur.
