(3）Machine set up

Choose the right place for bed,

The bed and worktable fixed by four nuts. When you fix the bed please consider

the following things: the machine should working for a long time and keep

acute, the machine should fixed in right position so that it can be working

good.

Considering the right environment,

1）Fix flat adjustable plate for the worktable

2）Don’t expose the bed in the sun, that influence the acute of bed

3）Do not place the bed in wet or damp environment, the steel can be rust in

that environment

Important measures for fix

1）Drill four fix hole on the bed surface（Attention：Choose the good position

to make sure the longitudinal handle (Y) can easily moving and operate）

to keep safety.

8． Please take care of the condition of the machine when you operate it,

if there are any abnormal sign, stop the machine at once and repair it.

(4) Transmission system

The transmission of the machine contained spindle timing belt pulley, spindle

bearing and motor timing belt pulley. When the brushless dc motor start, the

motor and the spindle timing belt pulley drive the spindle rotation, and then

the machine worked. Spindle speed can be changed freely at the speed range.

The spindle speed is 100-1600 r/m, and you can see the present speed on the

spindle LCD screen.

(5) Operation and maintenance

Operation Step for Mechanical Switch and Speed Switch

1、plug in the wire to an outlet, rotation the switch to “ 1”,and then the

power will be bright which means the machine has electrified.

2、Loose the emergency stop switch, close the protective cover for the spindle,

then you can see “0000”, “FORWARD”and “STOP”on the LCD screen.

3、Press “START”，the spindle will start working，there will be “0100” on

the LCD screen，and the speed is the lowest.

4、You can rotate the speed switch from 100-1600 r/min，and it will be signed

on the LCD screen.

5、Switch the button to “TAPPING”，and the machine can tapping screw

threads( and the machine have reverse function only when you switch the

9

button to “TAPPING”），push the button on the spindle handle , the machine

can tapping in direct-adverse direction, and on the LCD screen there will

be “FORWARD”or “REVERSE”to show the present condition.

6、When you want to use the small feed function, firstly you tight the handle

on the right, the 3 operate handle with button was locked ,and then switch

the small feed handle on the right can real the small speed adjustment.

7、Push the button “ UP” or “DOWN” to control the spindle (Z) move high

or low . “UP” is up quickly, and “DOWN” is down quickly. The machine

cannot use this function when the machine is milling. The cutter is adjust

before milling, you can adjust the cutter to right place according to the

height you want to cutting, and then lock the spindle handle and make the

machine working .

8、Horizontal milling can be realized by spindle rotation. First ,loose the

fix parts on the left land; Secondly, rotation the spindle and let go your

hand, .When you rotate it to left, there will be a limit angle to prevent

the angle more than 450. When you rotate it to right it can realize the

function of horizontal milling, you can see the angle number on the LCD,

rotate it to the angle you need and then lock the 3 nuts.

9、Push “EMERGENCY STOP” , and the machine will be stopped. In urgently moment,

push the “EMERGENCY STOP”button , the machine can stop at once ,and then

you can deal with the question. When the question settled, you can start the

machine again.

10

OPERATE THE MACHINE

2、Clean the inner of the spindle (MT4)and cutter, put the cutter into the

spindle nose, put in the stem and lock it.

3、You should clamp all the parts you want to process and then adjust to the

right position.

4、Loose the lock handle of column, swing the up-down handle to lower the

spindle.

5、Start the machine, adjust the speed, swing the multipurpose handle, and

then the machine can start to mill.

6、When you milling the work piece, please lock the spindle and headstock.

In order to prevent size change during the work, please lock the

longitudinal and lateral gag.

7、When you change the drill chuck or mill chuck, loose the protective cover

and put it aside, then relative the screw, use the hammer to remove the

taper-shank from spindle, and then loose the stamp to change the drill chuck

or mill chuck.

After use the machine, please cut off the power, clean the bed and fill some

oil on the surface of the bed to prevent been rusted to keep beautiful and

function.

Gag adjustment

11

When the bed worked for a long time, you should adjust the bed and gag to prevent

error, to keep the reliability and accuracy.

The part should adjusted as follows,

1）The lateral gag between bed and saddle.

2）The longitudinal gag between saddle and base.

3）The gag between headstock terminal pad and column.

Adjust measures: adjust the gag until the handle ( a )easy to moving and stable,

and the bed has no feeling of loosened. And then lock the screw.
