1. INSTALLATION
1-1 Machine Installation
When installing NC machine, solid foundation is essential. It is also most important for maintaining
the best condition of cutting accuracy of the machine. The nature of the ground condition of the
factory site, for example, rock base or reclaimed land, makes a big difference. It is, therefore,
difficult to give any definite rules generally applicable to the installation of this machine. (Refer to
the foundation and arrangement drawings.)
The followings are the concrete items to be carefully attended when installing this machine.
2
1) The bearing capacity of soil should be 5 ton/m
be 300mm or thicker.
2) The area of the foundation should be extend to at least 300mm outer circumference of the
machine bed.
3) When digging vibration proof drains, they should be dug along the circumference of the
foundation.
4) Placing separate concrete blocks underneath each machine leg instead of a real foundation is
often seen, which is just not adequate. Such is no value as proper foundation,
or larger and thickness of the foundation should
As this machine yields large volumes of chip during machining, carts are often used for chip
disposal. The traffic of carts and detaching covers in maintenance work need free space so that
the operators can move around without touching other machines. This factor should be
considered when selecting the installing position of the machine.
1-1-1 Environment of the Machine
Pay full attention to a room temperature, dust, vibrations, etc. in order to make use of the
primary performance of the machine. High accuracy cannot be obtained in the environment
where the room temperature greatly changes. Just a slight change of the room temperature
partly affects the machine. Be fully careful of effects heat transfer from the direct sunshine,
vent, heating unit, and so on.
Under the environment where the air is polluted so much by dust, etc., the sliding sections and
electric devices of the machine are greatly effected in their service lives.
Particularly, electronic devices related to controls are susceptible to dust and humidity. Install
the machine in the environment as clean as possible.
1. Installation Environment of NC Machine
In case that electric machines and appliances generating high frequency noise are
installed or newly erected near by NC machines, keep to the following precautions.
1) Example of the electric machines and appliances generating high frequency noise.

1-3 Transportation of Machine
Since this machine has an integrated structure mechanically and electrically, it can be
transported only by detaching its power cord. To fix its moving parts and pass wire ropes
around the machine, refer to Fig.1-1.
1-3-1 Precautions for Lifting Work
Pay proper attention to lifting work, because it is one of important steps when transporting
the machine.
! WARNING
Since the lifting work for machine transportation is carried out with a crane or chain
block, its precautions are listed below:
(1) Use a wire rope whose diameter is 14 mm (0.55 inch) or more.
(2) Apply a pad to an acute-angle part to protect the wire rope and machine.
(3) Pass the rope so that the center of gravity of a load will come over the center line of a
lifting angle.
(4) Do not use a rusted wire rope, one which has been untwisted, or one whose core wire
is broken.
(5) Lift the machine gradually. Stop it once when the wire rope become strained, and
check a lifting conditions. When the machine is lifted up from the floor, check again
that there are no abnormalities with the lifting rope, and proceed with the lifting rope.
When lowering the machine, it is necessary to be careful that it is lowered down slowly.
Stop lowering the machine immediately before it reaches the floor to check.
Then, lower it down completely.
1-3-2 Precautions When Using the Forklift
! WARNING
Since the lifting work for machine transportation is carried out with a forklift, its
precautions are listed below:
1 - 5
(1) Select a fork lift which has a sufficient capability to handle and endure a machine
weight.
(2) In order not to damage the outer projected parts of the machine, it is necessary to
carry out this work in cooperation with a watchman.
(3) When inserting the fork under the machine, use the right and left cast grooves
provided for fork insertion under the base of the machine proper.
(4) When lifting the machine, be sure to carry out temporary lifting so that you can lift it
with the center of gravity of the machine set at the stablest positions in both
longitudinal and crosswise directions.

1-5 Air Supply
This machine uses clean air to clean the spindle hole and the tool, for Z axis sliding face and
automatic door, or for oil mist unit. The air supply should be prepared by the customer.
Its joint of the machine is of PT1/4, female.
Air pressure : 0.5MPa {5 kgf/cm2} (72 PSI) or more
Flow : 100
*It is recommended to install an air tank having a capacity of 40• or larger, as there are cases
when supply of a large volume of air is needed instantaneously.
The machine proper is provided with an air filter and regulator to remove dust and
supersaturated moisture from air. When the temperature of the air from the air supply is
higher than that of the machine proper, air gets cooled at the machine proper and tends to
form water drops.
Jetting air containing water is prone to cause rust on the spindle hole and tool shank, which
may affect machining accuracy and cutting surfaces. Therefore, the temperature of the air
from the air supply should below. (Water and dust accumulating in the air filter is automatically
drained. To manually drain them, see the descriptions on mechanical drain operation.) In
case there is a large difference in temperature, install an air drier between the air supply and
the machine.
Flow rete
•/min. (ANR) (Standard Specification)
The flow rate to be set varies depending on the option specification. Therefore, the flow rate
applicable to the actual machine should be determined by the flow rate for the standard
specification machine added by the total required flow rate for the option specification.

1-6 Oil Supply
When adding lubricating oil, take care of the following:
1. Add the specified amount of the designated oil. Do not use different oils, and do not add to
much of oil.
2. Clean the oil supply port in advance. See that dust, etc. do not enter.
3. When adding oil, set a filter on the oil supply port, so that dust and other foreign substance
will not enter. In case a filter is not available, use a wire netting of 150 mesh or more.
4. Always use new oil. Do not use a mixture of new and old oil.
5. Even when using new oil, do not use all the oil from the can. Always leave some oil in the
can. This is necessary to avoid sediments in the can being used.
For the oil supply positions, intervals, oil amount and quality, see “5-2 Lubrication and Oil

Supply”.
1-7 Mounting Procedure
(1) Dismounting fixtures for shipment and transportation
Upon installing the machine at a fixed place, be sure to dismount the fixtures for
shipment/transportations .
• Remove the fixed plate for the table, column and head.
(2) Installation
A leveling method is one of the factors which determine machine accuracy. Proper
leveling of the machine is most fundamental.
Carry it out carefully, because it affects not only machining accuracy, but also machine’s
service life.
First, put leveling pads at installation points on the floor.
Install the machine so that the leveling adjust bolts attached to the machine legs will be
placed on them.
Use precision levels whose sensitivity per graduation is’ about 0.02 mm/m (0.00025 in./
ft.) and length is about 200 mm (8 in.).
Levels used for woodworking/engineering are not recommendable.
Place the levels with the same end in the same direction.
Keep level-placing surfaces clean at any time lest dust, etc. should be caught under the
levels.

Adjust the level of the machine with the leveling bolts so that each difference in
reading of the levels may be settled within 0.04 mm/m (0.0005 in./ft.) in both X and Y
directions.
[3]Adjusting the table operating level
Place the levels at the center of the table and move the X axis almost over its full
stroke. Make adjustment in such a way that each difference in reading of the levels
at this time will meet within the following target values:
• For the level put in the X-axis direction: 0.02 mm/m (0.00025 in./ft.)
• For the level put in the Y-axis direction: 0.04 mm/m (0.0005 in./ft.)
[4]Reconfirm the above-mentioned steps [1] through [3] and make fine adjustment, if
necessary.
[5]When the stable operating levels in [3] cannot be obtained, it is likely that the
condition of the floor, where the machine is installed, is improper. Check and improve
it, referring to the foundation drawing.

2-2 Lubrication, Oil Supply and Coolant
When supplying oil, be fully aware of the following:
1. Supply specified oil by specified amount. Do not supply a different type of oil or over the
specified amount.
Otherwise, the machine may malfunction.
2. Clean an oil inlet port in advance lest dust, etc. should enter inside.
3. When supplying the oil, use a filter to prevent foreign substances from entering inside the
tank.
When the filter is not available, use a wire net of 150 mesh or more.
4. Whenever you supply the oil, use new one. Do not mix with reproduced or old oil.
5. Even when opening a new oil can, do not use all oil in it, but leave some unused. This is
necessary to eliminate moisture and deposits.
See the lubrication chart for lubricating points, lubrication frequency, oil quantity and oil types.
