Leveling the machine first, required tolerance should not be over 0.04/1000 both in horizontal and cross plane.
Checking all items of the accuracy as per the table sheet of the certificate. Accuracy value for each checked
item must not be over the required value.
6.3 Preparation before machine running:
A strict checking, testing and try cutting of the machine have been made before machine delivery. No
adjustment of the machine itself is necessary. Before machine running, clean all surfaces of the machine first
by using cloth with kerosene or gasoline, checking all lubrication points then turn the main switch of the
machine to the “on” position, running the machine with middle or slow speed and checking all revolution
direction is correct, operating levers are in a correct position, checking machine noise and working
temperature are all ok. The machine should be running for a certain period of time, then it could be used if no
any un-normal condition happened.
7 Use and operation of the machine :
7.1 For the operating levers, handles, electric switches and buttons, please refer to the diagram 1 and diagram 4..
7.2 Mounting and dismounting of tool cutters:
The machine equipped with a tool dismounting device to be controlled by a knob ( 12 ). Push forward the
knob ( 12 ) to the spindle box direction when tool mounting is required. As for dismounting tool cutters, pull
out the knob ( 12 ), hold the tool cutter by left hand, meanwhile, turn the feed lever ( 5 ) by right hand, then
the spindle quill goes up rapidly, the tool cutter will fall down until tool taper shank strokes the shaft of
spindle.
In case too tight mesh between tool shank and spindle taper and the tool cutter could not fall down after
several strokes, then you have to use the normal way by using a taper wedge to dismounting the tool cutter.
Warning: The knob (15) must not be pulled out while tool mounting or machine
Running, otherwise, the spindle will goes up quickly which results tool
cutter falls down. It is really dangerous.
7.3 Changes for the spindle speed and feed rate:
Spindle speed change could be made by moving the two levers ( 13 ) and frequency
transducer timing button ( 14 ) located in the front of the spindle box. Relations between
spindle speed revolution and levers position is indicated at the speed change label.
Meanwhile, the digital meter indicates the actual spindle revolution.
As mounting or dismounting tool cutter or adjustment of work piece needs spindle rotation by
manual, therefore, the lever in the right side position shall be in the “idle” position, so spindle
rotation could be easily obtained.
Changes of the feed rate could be realized by using the lever ( 11 ) in the upper right side
position of the spindle box.
