4.4 Spindle and its balancing structure
Adjust the balance of spindle:Unti-clockwise loosen the screw 1, which can increase the
balancing power. Otherwise, reducethe balancing power。
4.5 Head clamping structure
Adjust the head clamping power. Loosen the nut 1 and remove the part 2,
which can adjust the power of head clamping. Generally speaking, put the
300N on the hand wheel, the head can’t shake.

5、Electric system
5.1 Brief
This machine use 400V、50HZ 、3 three phase alternating current . Control circuit and
illume circuit was used by control transformer which reduce the pressure , the voltage is
110V、24V fitted for all kinds of electric component , are all listed on the detailed electric
component list .
In order to drive all mechanism ,motors installed on the machines are as follows ,
M1-------------general motor
M2-------------up and down motor
M3-------------cooling pump motor
Switchboard is on the under-front of column , cooling pump motor is equipped on

MachineTools OPERATINGINSTRUCTIONS

the base ,column clamping motor installed on top of the column, other electric
equipment on spindle body or arm . Because there is no junction station on top of the
column , so do not always turn the arm continuously to a direction when in operation ,
in order twist off line Which cross the inner the column.
5.2 Explain of circuit
(Figure5-1 Electric principle map，Figure5-2 Electric wiring diagram)
(1) Turn on the electricity switch QF(SAI), indicator light HL1 and button indicator
light HL2 HL3 connected.。
(2) general motor circumgyrate
press start button SB2 ,turn on the contactorKM1 , then spindle circumgyrate
clockwise , indicator light HL2 off ;press button SB3, contactor KM2 connected ,
spindle circumgyrate unti-clockwise ,indicator light HL3 off .Spindle stopped
circumgyrate when press button SB4 In prevent of long time operation about general
motor , there is a relay FR ,it’s fixed value should adjust by the rating current of
general motor M1 .
(3) Arm up and down
First release the arm clamping handle 3 ,micro-switch SQ1 closed , press uplift
(or down) button SB5(or SB6) .contactor KM2(or KM3) absorbed ,up and down motor
M2 circumgyrate , drive the arm uplift. When arm Uplift (or down) to the places you
needed ,loose button SB5 (or SB6) contactor KM3(or KM4) released ,up and down
motor M2 stopped circumgyrate . Arm stopped up and down .
Up and down limitation switch SQ2, SQ3 use to control the arm up and down .
Arm stopped when uplift to the limitation place SQ2(or SQ3), contactor KM3(or KM4)
off ,up and down motor M2 stopped circumgyrate . Arm stopped up and down .
(4) Start and stop of the cooling pump
You can connect or cut off the electricity by turn the combination switch to the
start /stop position Then the cooling pump motor M3 start and stop .
5.3 Maintainance of the electric equipment
When check up with the electric equipment , you must make sure that the
general electricity has turned off .
In order to keep electric equipment clean, you .must clear the dust ,dirty
things and oil after a time. You can use blower clean dust but do not use
kerosene 、gasoline to clean winding . contact place must clean clearly ,change
another one if fraied . Slightly burned or frayed contact head should be
repaired by file .
* When spindle interchanged clockwise and unti-clockwise , you need to
press button SB4 and then press SB3(or SB2) if unnecessary .
