NOTICE
The following safety instructions are general recommendations for most
common operations on a turning machine.
Additional safety measures may be required for your particular application.
Therefore, makes no warranty or representation as the absolute correctness of
sufficiency of the instructions.
1.1 General safety instructions for operating the machine
1) The best defense against injuries on a turning machine is to be alert. Never
initiate a machine function unless you completely understand what the
function will cause the machine to do.
2) Never operate the machine with any cover or shield opened or removed.
3) Never reach into the work area when the spindle is rotating or if the machine
is in automatic mode.
4) Put the machine in manual mode and be sure last programmed function has
been Completed before reaching inside of the work area.
5) The functions of the machine make it impossible to eliminate all pinch points.
Be particularly aware of the following pinch points:

1- 3
* Spindle and chuck rotation
* Indexing of turret and tools
* Carriage and cross-slide movement
* Tailstock movement, both quill and body
6) Keep machine and area around it clean and well lighted. Never allow chips ,
coolant or oil to remain on the floor. Do not leave loose objects on around
machine.
7) Clothing :
* Wear safety glasses with eye shields at all times. Protect your eyes. Never
use a compressed air house to remove chips from a machine.
* Never wear loose fitting clothing. Remove all jewelry (rings, watches,
necklaces…etc.). They can be caught in moving parts of the machine.
* Gloves are easily caught in moving parts. Take them off before turning the
machine on.
* Always wear safety shoes with steel toes and oil-resistant soles.
* Wear a safety helmet when working near overhead hazards.
* If operator has long hair, hair should always be tucked under a cap or tied
back and up.
8) Turning machine are designed to be run by one person. Persons other than
the designated operator should stay out of the machine area during
operation.
9) Take care, not to bump or accidentally touch the machine control. Doing so
can initiate an unintended machine movement which could cause an injury
or a wreck.
10) Do not paint, alter, deface or remove any warning plates from the machine.
11) Report any loose, worn or broken parts to your supervisor. The same action
should be taken if any unusual noise or machine action occurs.
12) Never operate the machine after taking strong medication, using
non-prescription drugs, or consuming alcoholic beverages. Persons with
illness, which might cause dizziness or fainting, should never operate this
machine.
13) The electric components are protected from normal moisture resulting from
humidity use of water base soluble coolant, etc. Do not, however, use water
house to clean the machine or the area around it.
14) Never touch a machine control device or electrical component when your
hand is wet. Keep flammable liquids and materials away from the work
area and chips.
15) Never clean up chips while the machine is running or is in automatic mode.
16) Do not file work pieces being rotated under power.
17) At the end of the work day the machine should be placed in either “control

1- 4
off” or “power off” modes.
18) When restarting a machine after it has been shut down, always assume it
has been tampered with. Recheck all phases of the job as though you were
running the first piece.
19) Never touch spindle start or spindle jog control until hands, feet, and body
are well clear of the work area.
20) Coolant and oils can make surfaces on the machine slippery. They can also
present an electrical hazard if the machine has power on. For these reasons
do not stand on any part of the machine at any time.
21) Never extend an unsupported bar out of the rear the spindle or hydraulic
cylinder a distance from a concentric support more than 10 times of it’s
diameter. Doing so can cause the bar to bend or break. When any bar is
extended, a large sign should be placed to warn people to stay away from
the area.
22) If your turning machine has a bar-feeder interfaced to it , keep yourself and
others away from the exit end of the bar-feeder when the machine running.
1.1.1 Safety instructions for work holding
1) Never run a job on this machine until you are 100% sure the work piece is
being held in such a manner as withstand the centrifugal force from rotation
and cutting forces of the tooling. If there is any doubt , whatever , consult
with your supervisor.
2) A chuck is the most common work holding device used on this machine.
Some of the factors affect the holding device used on this machine. These
factors which affect the holding ability of a chuck are :
* Clamping force of jaws
* Rotational speed of the spindle
* Type of jaw surface (serrated , smooth , etc.)
* Area of chuck configuration of the work piece…shape, weight, and balance
* Jaw weight and location
3) With air or hydraulic actuated power chuck (optional accessory) , make sure
the jaws are gripping the work securely before they reach the end of their
travel. When using a power chuck, check the hydraulic or air pressure before
every operation. Low chucking pressures will diminish jaw-dripping force,
which may allow the work piece to come out of the jaws. Excessive pressure
can damage a power chuck, which could cause a loss of jaw force. The
gripping force of a power chuck can be diminished as much as 50% because
lack of lubrication or lack of periodic cleaning. Components of the chuck are
subject to wear and damage which also can lessen gripping power. Grease

1- 5
the chuck at the beginning of every shift. Use only the chuck
manufacturer’s recommended lubricant.
A. A weekly examination of the condition of chuck should be made. This
examination should include the measurement of jaw clamping force with
a jaw force gage to insure that the chuck is function , as it should.
B. Refer to manufacturer’s manual for chuck and cylinder for any other
maintenance requirements. As the spindle R.P.M. increase the gripping
force of the jaw decreases. The larger the chuck diameter the more loss
becomes. Various types of top jaws are serrated contact surfaces on
work piece. Improper usage could cause serious injury or death.
Remember-chucking a work piece safely involves many variables. If you
have the slightest doubt regarding the safety of your set-up for a job ,
consult with your supervisor.
4) Never operate spindle-mounted accessories over their rated speed. If the
chuck or accessory is not supplied by original maker, verify the safe
operating speed with the manufacturer.
5) Always be sure the chuck the chuck or accessory is located correctly on the
spindle nose and it is securely bolted the face of the spindle.
6) Be sure any item bolted or clamped to a chuck or fixture is securely fastened
before starting the spindle.
7) Proper lifting equipment should be used for heavy chucks, fixtures, and work
pieces.
8) Always is aware f that closing chuck jaws could trap fingers or hands.
9) The same safety instructions that apply to power chucks also apply to
manual operated chucks. The following additional precautions should be
taken when using a manual chuck :
A. Always use spring-loaded, self-ejecting type safety wrenches.
B. Never put an extension bar on a chuck wrench or hit with hammer.
C. Never run a gear scroll chuck without having something chucked in the
jaws. Centrifugal force can cause the scroll to unwind if the chuck is
empty. If this occurs, the jaws may come out of the chuck while the
spindle is turning.
10) If a work piece is extended from the chuck a distance of 3 to 4 times its
diameter, without being supported by the tailstock, poor cutting condition
will normally occur. Under no circumstances extend an unsupported work
piece more than this amount without supporting the work piece with the
tailstock. Doing so can cause the part to bend or break.

1.2 Maintenance safety instruction
WARNING
High voltage is used to power the machine; only authorized electricians should
Correct any electrical component failure. Disconnect main power and lock in off
position before attempting any repair. Tag disconnect switch “DO NOT START”
1) Read and understand safety instructions for machine operator before
servicing this machine.
2) Know all points where high voltages are present on this machine and in
electrical boxes.
3) Residual voltages can exist in electrical cabinets for a period of time after
power has been turned off. Check any component inside cabinet with a meter
a before touching.
1.3 Installation precautions
To ensure the safe operation of the NC machine, note the following during
installation.
1.3.1 Wiring
1) Be sure to use electrical conductors with performance ratings equivalent or
superior to those described in the Maintenance Manual.
2) Do nut connect to the power distribution panel any power cables for device,
which can cause Line noise, such as ,are welders and high frequency
quenching machines.
3) Arrange for a qualified engineer to connect the power lines.
1.3.2 Grounding
Use a grounding wire with a cross section of more than 14 mm and a resistance
to ground of less Than 100 ohms.
This wire size should be greater than AWB (American Wire Gauge) No. 5 and
SWG (British Legal Standard Wire Gauge) No.6.

1- 7
Generally, the NC machine should be ground to a separate grounding rod. If an
independent ground cannot be provided for the machine, prepare the ground
connection as follow:
1) Connect a single conductor to it’s own grounding terminal. This will avoid
possible serious accidents resulting from ground currents ,which might
otherwise flow in the NC machine if a peripheral device , should malfunction.
2) Be careful when using concrete reinforcing rods as grounding points. These
reinforcing rods often are used to ground equipment because they usually
offer a resistance to ground of less than 100 ohms. In doing so, make the
connections as follow:
A. Do not use the same grounding-reinforcing rod or grounding terminal for
other devices since this could lead to line noise such as produced electric
welders and high frequency quenching machine.
B. Use a grounding terminal with an adequate electrical performance rating
and which is durable.
3) A separate grounding wire should be used, one whose length is as short as
possible.
4) Check the resistance to ground by actual measurement. This should
measure less than 100 ohms if the single device is connected to its own
grounding rod.
Desirable Independent Grounding:
Common grounds:
Never ground equipment as shown in the left side figure (FORBADE ) :
Earth resistance: Less than 100 ohms
Resistance to ground = 100 the number
of devices connected to the grounding
(Ω)

1- 8
(Wrong Grounding)
1.3.3 Environmental conditions
Generally, the machine will be installed on the following conditions. However,
these may change over a period of time or in response to seasonal changes.
1) Supply voltage : 90% to 110% of nominal supply voltage
2) Source frequency : ± 2hz of nominal frequency
3) Ambient temperature : 0℃to 45℃(32℉to 113℉)
4) Relative humidity : Less than 80%
Temperature changes should not cause condensation.
5) Atmosphere : Free from excessive dust, acid fumes corrosive
gases and salt
6) It should be avoided to expose the machine to direct sunlight or heat rays
which can change the environmental temperature.
7) Avoid exposing the NC machine to abnormal vibration.
If it is difficult to observe meet these conditions, contact us immediately.
