Additional safety measures may be required for your particular application,
MlCROWEILY therefore, makes no warranty or representation as to the absolute
correctness or sufficiency of the instructions.
1. 1GENERAL 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 open or removed.
(3) Never reach into the work area when the spindle is turning or if the machine is
in automatic mode.
(4) Put the machine in manual mode and be sure last programmed function has be
completed before reaching inside of the work area

-4-
(5) The function of the machine make it impossible to eliminate all pinch points,
bc particularly aware of the following pinch points:
-Spindlc and chuck rotation
-Indexing of turret and tools
-Carriage and cross slide movement
-Tailstock movement, both quill and body
(6) Never allow chips, coolant or oil remain on the floor, do not leave loose object
on or around machine.
(7) Clothing:
*Wear safety glasses with eye shields all times.
*Never use a compressed air hose to remove chips from a machine
*Do not wear rings, watches, tie or loose sleeve clothing.
*Gloves are easily caught in moving parts, take them off before
turning machine .
*Always wear safety shoes with steel toes and oil resistance soles.
*Never remove protection for even a short time when operating the
machine.
*Know the correct way to wear protective devices.
If operator has long hair, hair should always be tucked under a cap
or tied back and up, beware of loose hair near the rotating parts of lathe.
(8) Turning machines are designed to be ran by one person, persons other than the
designed operator should stay out of the machine area during operation.
(9) Take care not to bump or accidentally touch any machine control.
(10) Do not paint, alter, deface or remove any warning plates from the machine,
replacement plates are available from MICROWEILY.
(11) Do not operate machine while talking.
(12) Never operate the machine after taking strong medication, using non-
prescription drugs or consuming alcoholic beverages. Persons with illnesses
which might cause dizziness or fainting should never operate this machine.
(13) The electric components arc protected from normal moisture resulting from
humidity use of water base solubles as coolant, etc., DO NOT use water
clean the machine or the are around it.

-5-
(14) Never touch a machine control device or electrical component when your
hand is wet.
(I5) Keep flammable liquids and materials away from the work area and hot chips.
(16) Never clean up clips while the machine is running or is in automatic mode.
(17) Do not file work pieces being rotated under power.
(18) At the end of work day, the machine should be placed in either
"CONTROL OFF" or "POWER OFF" modes.
(19) When restarting 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.
(20) Never touch spindle start or spindle job control until hands, feet body are
well clear of the work area.
(21) Do not stand on any parts of machine while coolant and oil make surface on
the machine slippery which present electrical hazard under machine has
power on.
(22) Never extend an unsupported bar out of the rear of the spindle or hydraulic
cylinder a distance from a concentric support more than 10 times its 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.
(23) If you work turning machine with bar feeder together, please keep away from
the exit end of the bar feeder when the machine is running.
1.2 SAFETY INSTRUCTIONS FOR WORKHOLDING:
(1) Never running machine until your workpiece was held 100% sure.
(2) A chuck is the most common workholding device used on this machine, some
of the 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 jaws in contact with the workpiece
* Type of chuck
*Configuration of the workpiece ...shape, weight and balance
*Jaw weight and location

-6-
(3) Before running machine, make sure the workpiece is gripping internally or
internally, since low chuck pressure will diminish jaw gripping force which
may allow the workpiece 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 ordiminished as much as 50% because of lack
of lubrication or lack of periodic cleaning, components of the chuck are
subject to wear and damage which also can lessen gripping power. Need
support workpiece by steady rest or tailstock center while workpiece length
over 200mm.
A. Grease the chuck at the beginning of every shift, use only the chuck
manufacturer’s recommended lubricant.
B. A weekly examination of the condition of the chuck, this examination should
include the measurement of jaw clamping force with a jaw force gage to insure
that chuck is functioning as it should.
C. With reference to manufacturer’s manual for chuck and cylinder to any other
maintenance requirements. As the spindle r.p.m. increase the gripping force
of the jaw decreases, various types of top jaws are used on chucks for different
applications, the best workholding conditions that need use serrated contact
surfaces on work gripping surfaces and use the maximum area of contact
between the jaws and the workpiece, improper use cause injury.
(4) If chuck or accessory was not supplied by MICROWEILY with machine
together, verify the safe operating speed by their manufacturer.
(5) Always be sure the chuck or acccssory is located correctly on the spindle nose
and it is securely bolted to the face of spindle.
(6) Be sure any item bolted or clamped to a chuck or fixture is securely fastened
before starting the spindle.
(7) The spindle speed could not be high speed during the workpiece too long.
(8) Always be aware that closing chuck jaws can trap fingers or hands.
(9) The same safety instructions apply to power chucks and manual operated
chucks, the following additional precautions for manual chuck when you use
it.

-7-
A. Always use spring-loaded, self-ejecting type safety wrenches.
B. Never put an extension bar on chuck wrench or hit it hammer.
C. Centrifugal force can cause the scroll to unwind if the chuck is empty.
the jaws may come out of the chuck while the spindle is turning.
(10) If a workpiece is extend from the chuck, the distance of 3 to 4 times it
diameter, without being supported by the tailstock, poor cutting conditions
will normally occur, check load capacity of revolving centres for application
in hand.
1.3 MAINTENANCE SAFETY INSTRUCTIONS,
(1) WARNING:Only authorized electricians can install or modify any electrical
component failure. Disconnect main power and lock in “OFF” position
beforeattempting any repair, tag disconnect switch “DO NOT START”.
(2) Read and understand safety instructions before servicing this machine.
(3) Know all points were voltages are present on this machine and in electrical
boxes.
(4) Residual voltages can exist in the electrical cabinets for a period of time after
power has been turned off. Check any component inside cabinet by meter
before touching.
1.4 INSTALLATION SAFETY INSTRUCTIONS:
(1) Verify machine weight and make sure lifting equipment, cables, etc., are
sufficient capacity, refer to follow MICROWEILY’s maintenance manual to
lift and move machine.
(2) MICROWEILY machine has transformer tapes for various voltages and power
cycles, if machine subsequently moved by user, the transformer taps must be
checked and be sure which are wired correctly for new location.
(3) A copper (5/8” minimum diameter) rod must be sunk through
foundation into the earth at the machine, length should be sufficient
to provide less than 80 ohms resistance between the end of the rod
and earth ground, a large copper wire must directly connect this
earth ground to the ground connection provided on the machine.
