1. OUTLINE AND FEATURES
This APC (automatic pallet changer) unit is based on “hydraulic unit less” system realized by VS
series standard model, and is featured by its ECO, ECO (ecology and economy) specifications
with high speed and high reliability. It enables men to relieve from periodic maintenance of
hydraulic oil required by the conventional system and to reduce the running cost.
1-1Configuration
1-1-1 Saddle (Pallet Table)
For the pallet clamp/unclamp action, high pressure (about 40kgf/cm2) hydraulic power
converted from compressed air amplified by air hydro-unit is used. Use of air pressure for
the purpose requiring high power such as pallet clamp unit has hitherto been generally
considered unsuitable, however, this problem has been solved by converting air pressure
energy into hydraulic pressure.
1-1-2 APC Main Unit
For the APC main unit, rotary arm type exchange system is adopted. The relative
movement of a rotary arm driven by an inverter motor and two lines of groves on the pallet
runs the system. Compared with the conventional hydraulic system, this system enables
smoother and quicker pallet change and, furthermore, higher reliability is achieved with
simple construction by reducing the number of parts nearly to a half.
1-1-3 Splash Cover
The processing area is covered with splashguard up to the ceiling as a fully enclosed
space. The processing area is separated from the APC rearranging area by an automatic
shutter driven by an electric motor for protection against the splash of coolant and chips.

4. TRANSPORTA TION AND INST ALLATION
OF THE MACHINE
4-1Transportation of the Machine
As the construction of this machine is a type that the machine is integrated with the electric
appliances, the machine can be transported only by removing the power cord. As to the
fixing method of the moving sections and the lifting work, proceed as shown in Fig. 4-1.
4-1-1 Precautions for Lifting Work
Since the lifting work is one of the important set-up works when the machine is transported,
sufficient care should be taken. As the machine is transported through lifting works by
means of a crane or a chain block, the specific cautions for the lifting work are described in
the below.
(1) Use wire ropes with a diameter not less than 14mm (0.6”).
(2) Put pads on the sections with acute angle in order to protect the machine and the wire
rope.
(3) The machine is required to be lifted in a horizontal positions of the under surface of the
bed, and it is undesirable that the pallet changer side may become lower.
(4) Do not use rusted wires, untwisted wires or wires of which cor cable is broken.
(5) When lifting up the machine, wind up the wires gradually, and when the wire ropes are
tightened, stop lifting once to chick the lifting condition. Then, when the machine is
lifted up from the floor, check again if the lifting cable is normal, and then lift the
machine to the required height. When lowering the machine, the machine should be
lowered slowly. Then, lower the machine onto the floor.
4-1-2 Precautions for Lifting Work by a Forklift
(1) Select a forklift of which capacity is sufficient for the machine weight.
(2) When operating the forklift, be sure to work together with a supervisor for checking the
lifting work so that the projected sections of the machine periphery may not be
damaged.
(3) When driving the forks under the machine, use the cast grooves for inserting the forks
that are located at the left and right sides of the machine base.
(4) When lifting the machine, be sure to proceed provisional lifting work to check the
gravity of the machine both in the front and back direction and in the left and right
direction so that the machine may be lifted at the stablest position.

4-2Environment for Machine Installation
Pay full attention to a room temperature, dust, vibrations, etc. in order to make use of the
primary performance of the machine. Needless to say that 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 affected 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.
Also, the machine must be installed at a place free from vibrations caused by other
machines.
In case that electric machines and appliances generating high frequency noise are installed
near by NC machines, or newly erected keep to the following precautions.
1. Example of the electric machines and appliances generating high frequency noise.

Select the rated sensitivity of 200mA.
2) Grounding is to conform to the 3rd Class standard (100Ω or less).
Do not make wire connection with constructional iron frame.
a)Electric wiring
Wiring provided for this machine connects between the machine proper and its
attachments only. The user is kindly requested to prepare wiring from the supply
power source to the control cabinet. Although an electric wire used for this
purpose slightly differs depending on a distance from the power source to the
control cabinet, it is necessary to connect with the one whose sectional area is
22mm2 (0.87”) or more.
b)Pneumatic source
Since this machine requires supply of compressed clean air for blowing off chips
and cleaning the spindle hole and tool shank part also for pallet clamp/unclamp
pneumatics and other use, prepare air source of a proper capacity. (pressure:
0.5MPa {5kgf/cm2} or higher, flow rate:100/min; ANR, tank capacity of
compressed air source; 40
or larger)
4 - 10
This pneumatic source must be naturally free from dust contained in the air and
oversaturated moisture. Due to a nature of the air, as the air temperature of the
pneumatic source increases higher than the temperature of the machine proper, it is
cooled on the machine proper side and causes water drops more easily. If moist air is
injected, it may rust the spindle hole and tool shank, thus having ill effects on
machining accuracy and a cutting surface. Therefore, the better, the lower the air
temperature of the pneumatic source is. When there is a great temperature
difference, attach an air dryer between the pneumatic source and the machine.
An air coupler 30SH + 2OPM (NITTO KOKI make) is attached to the machine.
Please prepare a 3/8” hose and hose band by yourself and connect it.
c)Oil supply
Usually there is no need of supplying oil, however, when it becomes necessary for
some reason, pay full attention to the following points.
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.
