3-2. Environmental Conditions for Installation
Environmental conditions required for installing the machine
Accuracy of the machine is greatly affected by the environmental conditions in which it is installed. Make
sure to use the machine in the following operating condition ranges.
Ambient temperature
(room temperature)
20 to 25
°
C (variation:
±
1
°
C max.)
Ambient humidity
55
±
15 % (non condensing)
Treatment for
waterproof and
drainage
If water leakage should occur, the floor surface and downstairs might be
damaged. Therefore, provide the floor surface with an appropriate treatment
for waterproof and drainage.
(The water leakage detection system by adding the drain pan will be available
soon. Please contact DISCO office or DISCO service office for the detailed
specification.)

quality
Consult your DISCO sales representative in the following cases:
・
When using except for deionized water
・
When using water including impurities that may have harmful effects on
the machine
Spindle coolant
temperature
20 to 25
°
C (hourly temperature variation: 2
°
C max.)
Spindle coolant water
quality
If water used is high in chlorine (Cl), iron (Fe), copper (Cu) or sodium (Na)
content or has high electrical conductivity, mechanical parts corrosion or
piping system clogging may occur.
Air
Filtration efficiency: 0.00001 mm/99.5 % or better
Residual oil content: Less than 0.1 ppm
Dew point: -15
°
C or lower
Power requirements
200 VAC
±
10 %, 3-phase
・
Leakage current: 15 mA or less.
If you use an earth leakage protective breaker at the plant facility side,
choose one ready for higher harmonic waves and whose sensed current is
30 mA or higher.
・
Significant voltage fluctuation must be avoided.
・
A momentary power failure must not occur with the employed power
source.
・
Do not use the machine in electrically noisy environments. A noise test has
been conducted on this machine in accordance with the standard below.
IEC: 61000-4-4
Electrical fast transient/burst immunity test (JIS: C61000-4-4
Electrical fast transient/burst immunity test)
Charge voltage used for noise testing:
±
2.0 kV
Vibration
Amplitude: 5
μ
m max. (10 Hz or lower)
Acceleration: 0.02 m/s
2
(2 Gal) max (10 Hz or higher)
Ground
Facility-side ground connection must be made according to the local
regulations.
Altitude
Altitude of 1000 m or lower
・
When the altitude of the site is higher than 1000 m, consult your nearest
DISCO.
