1. Guideline for Safety Operation
The lathe is a high speed and powerful machine and can cause danger if operate it
improperly.
Before operating the lathe please read the following guidelines of safety operation.
Take care and observe to make the lathe be under normal operation environment so as
to avoid danger.
The lathe is in accordance with GB15760-1995 <General Technical Condition of
Safety Protection of Metal Cutting Machine> issued by the state.
The manual covers information and hints necessary for proper and safe operation of
the lathe.
It is required the operator of the lathe should accept suitable technical training
before operating the machine, own skills to operate it and hold the certificate of
operation; or he should be trained under the close supervision of somebody who can
skillfully operate the machine.
The lathe should be operated under the environmental temperature of +5°C - +40°C;
the elevation up to 1000 m; the relative humidity of 50% when ambient temperature is
+40°C or higher relative humidity if ambient temperature is lower.
The manual also covers related information for those who owns necessary skills or
appointed persons to make suitable maintenance upon the machine.
1-1 Safety Points for Attention
1. Keep the lathe and the working area clean and in good order.
2. All guard devices and cover plates should be on the place; the side cover should
be closed.
3. Do not place any objects in the processing area of the lathe as they may bump
with rotating or moving parts.
4. Do not contact or leap over moving or rotating parts of the lathe.
5. Before starting the lathe, you should understand how to stop it.
6. The lathe cannot be operated under overload.
7. Stop running of the lathe immediately in case any accident occurs.
8. When mounting the chuck or other attachment on the spindle, switch off power
supply of the lathe to prevent rotation of the spindle.
9. Do not mount the jigger if it is not checked of confirmed to be compatible with
the lathe.
Operation Manual of Horizontal Lath

10. Check the center you used if its load capacity can meet with requirement.
11. Switch off power supply before leaving the lathe.
12. The maximum weight of the workpiece on the lathe is 200 kg.
13. The chuck should be properly and firmly mounted on the spindle of the lathe.
14. Take care that the workpiece should be gripped firmly and the speed of the
spindle cannot exceed the safe speed of the chuck.
15. As it is possible to contact with human body, especially when the material with
small diameter is used, it is not allowed in any case that the rod material cannot
extend out the end of the spindle of the headstock which has no special guard and
relative support.
16. There is the label of that no speed change is allowed in operation at the
headstock, the electric warning board at the electric cabinet (box) and that no
touch on the workpiece (or chuck) when it is rotating on the guard of the chuck
to remind you to take care.
1-2 Danger of Operation
When operating the lathe you should fully understand the danger of following
operations:
1) Cutting Fluid
The cutting fluid is hazardous to human body. To contact the cutting fluid
continuously especially the original fluid, it can cause the skin allergic or ill if
seriously, even the emulsion can also cause the same. Therefore following precautions
should be taken:
a. Avoid any unnecessary contact.
b. Put on the protective clothes.
c. Adopt guard shield or plate.
d. Do not wear oily or dirt clothes.
e. Clean all parts of the body where the cutting fluid is contacted after work.
f. Do not mix different cutting fluids.
g. Replace the cutting fluid regularly.
h. Correctly treat the cutting fluid.
2) Safe Operation of the Chuck of the Lathe
All jiggers of work pieces should have clear labels of the maximum safe speed and
the speed of the spindle can never exceed it. It should point out that the maximum safe
speed on the label is supposed under ideal work condition and lower speed of the
spindle should be selected in following cases:
a. Adopt the chuck to jig the workpiece under noisy work condition.
b. If the chuck is surely damaged, it is dangerous to operate under high speed,
Operation Manual of Horizontal Lath
6
especially when the chuck of grey pig iron is used it shall break if it is something
damaged.
c. If no griping force is known before jigging.
d. All factors such as strength of the workpiece to be jigged, balance of the jigging
faces and the workpiece etc. can largely affect the maximum safe speed.
When the workpiece is rotation, it may not be jigged firmly due to the role of
centrifugal force and following factors may be involved:
a. The speed is too high.
b. The weight and type of the claws are off standard.
c. The working radius of the claw is unsuitable.
d. The claw ahs bad lubrication.
e. It is unbalanced.
f. The dynamic factor is not considered in the jigging force.
g. Too large cutting force.
h. Is the workpiece jigged internally or externally?
These factors should be seriously considered as they can cause different influence
in different purposes. The manufacturer cannot provide concrete data for general use
as they are beyond the range controlled by the manufacturer of the machine.

1-4 Protection of the Chuck
The lathe is equipped with the guard of the chuck (option), which is suitable for the
standard chuck.
In case the chuck guard is equipped on the lathe, it should be in a closed status
before the spindle is running.
1) When the machine is equipped with larger chuck, the chuck guard should be
replaced with one which has corresponding diameter with that of the chuck.
It is suggested that claws cannot extend out the outer diameter of the chuck in order
to avoid bump with the chuck guard. For the sake of safe operation, always take care
not to extend claws out of the outer diameter of the chuck.
2) When the face chuck is used, the chuck guard should be removed. If it is indeed
required by customer, the special chuck guard can be provided but it should be
confirmed that only the face chuck is used and any case should be responsible by
customer himself.
1-5 The Use of Emery Cloth in Metal Processing Can Cause Danger
In all accidents occurred on the lathe, most are from the use of emery cloth to cause
breakage of fingers, or even to amputate occasionally.
When workpieces with different shapes are rotating on the lathe, if using emery
cloth to deburr, to polish or to process finished sizes, it can cause the accident when
winding emery cloth on the workpiece to be ground by two hands. If winding the
emery cloth on the finger or to make rough grinding, the finger could be seized firmly
to cause serious injury.
