1-1-1 Precautions on Machine Operation

Before trial run, read this manual carefully and understand, the contents well. Witness of our
operation instructors is most recommendable.

MAINTENANCE

1. An operator and maintenance personnel should read the precautions on the caution plate
fitted to the machine and observe them.

Don’t stain, damage or remove the caution plate. If the caution plate becomes hard to read,
contact Hitachi Seiki.

2. Close all the doors and covers except when adjusting work is made.
As for the doors of the NC unit and the power control cabinet, be sure to close them with

special care.

3. Don’t remove or modify the limit switches for the stroke end, for the traveling axes and the

LUBRICATION

Since lubrication oil exerts a great influence on machine durability and accuracy, extreme care
must be taken for maintenance of the whole lubricating system. Perform the following check
and maintenance precautions.

1. Fill with the oil specified in the Maintenance manual to the specified amount.

2. Clear the oil port in advance and be careful that foreign substances such as dust, water and
chips do not enter the tank.

3. Check the bottom of the oil jug to see if there is any debris, water or cutting chips, etc.
insides Sufficient care is required to distinguish the oil jug by appropriate color coding and
fixed stock location to avoid mixed use of different kinds of oil.

4. Check the oil periodically and if foreign substances are found, clean the inside of the tank
promptly and replace it with new oil.

Don’t use all of the oil, even from a new can. This is necessary in order to remove water
and sediment etc.

(with option device)

5. Although low levels in the lubrication oil tank are detected by a float switch that flashes an
alarm signal, check to see if discharging is normal. There are two possible problems:

Oil in the tank decreases extraordinarily fast, or it is decreasing too slowly.

6. As for the suction filter fitted to the pump and the in-line filter in the piping circuit, replace
them with new ones once a year as a rule.

7. Air in the main lubrication pipes has been bled when the machine is delivered, but when the
piping is removed for maintenance, bleed air completely at the time of reassembly and
operate the machine after checking the state of discharging at the end.

COOLANT

The soluble cutting fluid is decomposed due to factors such as mixture of lubrication oil and
propagation of micro-organisms that lower cutting and rust prevention efficiency. This causes
various troubles to occur.

When using-soluble cutting fluid, care must be taken of the following points.

1. When selecting soluble cutting fluid, carefully consider lubrication, infiltration, rust

prevention, bubble prevention, reparability against oil and safety needs.

2. Before operation starts and after operation ends, not only remove chips, but also wipe off

soluble cutting oil adhered to each slideway, the rotating parts, the saddle and cross-slide
of the machine and then be sure to apply lubrication oil thinly to those parts.

3. Replace soluble cutting fluid immediately if it becomes vitiated.

1 - 3

4. Remove the covers every half year and clean each slideway, X, Y, Z axes ball-screws, each

limit Switch and feed motors etc.

5. As soluble cutting oil is considered for rust prevention, it may be no problem when the

workpiece is wet. However, when dry, it is apt to rust.

Therefore, it is recommendable to apply rust preventive oil before the workpiece dries after

finished machining.

6. Since soluble oil is alkalescent and has a strong degreasing action, the operator is apt to

develop dermatitis.

Therefore, the operator should take appropriate precautions.

7. As for the diluting method and soluble cutting fluid, diluting water they are different

depending on the type of soluble cutting oil, so use it in accordance with the
recommendations of the cutting fluid manufacturer.

8. Since there are instances where extensive micro-organisms are detected in industrial

water, it is recommendable either to check it before use as water for dilution or to use
service water.

9. Do not use a chemical solution type (synthetic type) in water-soluble cutting agents,

because it causes detachment of coating anf affects sealing materials and resin materials
adversely.

10.The influences of difference kinds of oil on coolant are as follows: Carefully monitor the

condition the coolant fluid.

OPERATION

1. Be aware of the position of the push button for emergency stop so that the operator may be
able to press it instantly.

2. As for the operation of the machine, proceed in accordance with the procedure described
later.

3. During operation, keep hands away from the rotating sections and movable sections.

4. When disposing of chips that wound round tooling or fell onto the table, it is dangerous to
grasp and pull them. Further, when disposing of chips, be sure to do it after stopping the
machine.

5. When adjusting the position of the coolant nozzle, do it after stopping the machine.

TOOL SETTING

1. When setting up tools, stop a spindle as well as the feed in each axis.

2. Set the tools within the specified lengths and diameters.

3. When setting a tool to the holder, be sure to set outside the machine. If set in the machine,
the spindle may rotate.

OPERATION FINISH

1. After operation of the machine is over, be sure to switch the power OFF in the prescribed
order, clean the machine and apply rust preventive oil to each section of the machine such
as the slide ways.

When soluble cutting fluid is used, perform these jobs with special care.

1-1-2 Electric Equipment and NC Unit

When operating the machine or carrying out maintenance checks, pay special attention to the
following points, concerning the electric equipment and NC unit.

1. Do not give shocks to the NC unit, power control cabinet and other machine parts.

2. For the primary wiring of the machine, use the cable size specified in the operation manual.
Do not use an excessively long cabtire cable.

When the primary wiring has to be put on the floor, protect it with a cover against damage
by cutting chips and other sharp objects.

3. While test running the machine, be sure the setting parameter of the NC unit coincides with
the parameter sheet attached to the machine.

4. Do not change the current set values of thermal relays in the power control cabinet, various
control knobs or the parameter data.

5. Do not apply excessive force, e. g. bending force etc., to the connector portion of plugs,
flexible conduits (tubes) or cabtire cables etc.

6. When carrying out maintenance checks on the electric equipment, turn off the
EMERGENCY STOP button on the operation panel, the power of the NC unit, the main
switch of the power control cabinet and the power switch installed in your factory, in this
order.

Start maintenance work after making sure that these switches are turned off. Lock the
power switches in the OFF state as much as possible or put up warning signs. In additions,
place a “DO NOT TOUCH !” tag near the operation buttons of the machine to forbid other
personnel from operating the machine.

7. Handle electric equipment of the machine with particular care and exercise extreme caution
not to allow the machine to get wet.

8. For equipment inside the power control cabinet, use those specified by Hitachi Seiki. Use
always specified fuses. Never use fuses with a higher capacity.

9. Never leave the control cabinet door open, because direct sunshine or camera’s strobe
flash rays may enter the cabinet and damage internal equipment.

10. In case of turning on the power again, execute power on went by equal to or more than two
seconds after power turned off. If the power is turned on during discharge from control
