5.1.1 Main shaft box: Six kinds of the rotation speed can be obtained by turning handle “1”and “2” accor-
ding to the speed change table. Be sure to stop the machine tool and then change the handle.
5.1.2 Feed box: Knob “12” is used for controlling the start, stop, clock-wise and reverse movement of the main
shaft. Turn the knob to the position “1”, the main shaft turns clockwise, to the position “0”, the main shaft stops
and to the position “2” . the main shaft turns reversely.
5.1.3 Apron: Turn hand wheel “11” and make the apron and machine tool in lateral movement manually. If
the hand wheel rotates clockwise, the apron and machine tool saddle move in the left direction and if the hand
wheel rotates counter clockwise in the right direction.
Handle “10” is used for controlling the opening and closing of the split nuts. When Handle “10” is closed,
the metric screw thread can be machined and longitudinal feed
can be done. Before operating handle wheel “11”, the handle must be opened.
5.1.4 Tailstock: “9” indicates hex nuts and are used for locking tailstock and fix it on the machine tool bed.
Turn hand wheel “8” for controlling the stretch and contraction of the tailstock. If the hand wheel rotates cloc-
kwise, the tailstock quill stretches, otherwise, the tailstock quill contracts.
Handle “7” is used for locking tailstock quill. Before operating hand wheel “8”, the handle must be turned
loosely. When the tailstock moves to the required position, lock it with the handle.
5.1.5 Machine tool saddle and tool carrier:
Handle “6” is used for operating small tool carrier movement. If the handle rotates clockwise, the tool carrier
moves forward, otherwise, it moves back.
Handle “5” is used for securing square tool carrier. If the handle is loosed, the square tool carrier can rotate,
otherwise the square is secured.
Handle “4” is for lateral feed operation, If it rotates clockwise, the lateral trail plate bring the tool carrier to
move forward, otherwise, the lateral plate moves backward.
“4” indicates a hex screw and used for machining end surface and fixing machine saddle.
6.2 Service and maintenance of the machine tool.
Keep the maintenance of the machine tool during the operation to guarantee the accuracy and service life of
the machine tool.
6.2.1 After the normal operation of the machine tool for 10 days, the lubrication oil inside the machine tool
head needs changing and then clean with gasoline or paraffin, which will be done later at set intervals.
6.22 Before the operation every day, the lubrication should be done according to the requirement of the
machine tool and timely examine the oil level inside the main shaft box .
6.2.3 During the operation, the chippings which falls on the sliding surface should be cleaned timely, and the
inspection should be often made to prevent chippings falling into the position between the machine tool saddle
and lathe
bed guide way. Asphalt felt should be cleaned at certain time.
6.2.4 After the operation every day, eliminate all the chippings and clean different part of the machine tool and apply
machine tool oil to prevent rusting.
6.2.5 In order to maintain the machining accuracy, take care of the center, the surface of the machine tool for the chuck
and the guide way and avoid mechanical damage and the wear due to improper guide.
6.2.6 If the damage is found, the maintenance should be done immediately
