Production process
Environmental Conditions |
• Use clean, oil-free air (dew point below -15, residual oil: 0.1 ppm, and filtration rating: 0.01μm/99.5 % or more).
• Keep room temperature fluctuations within ±1℃ of the set value (Set value should be between 20℃ - 25℃), indoor humidity no more than 80% and no condensation.
• Keep cutting water and cleaning water 2℃ above room temperature (fluctuations within ±1℃). Keep temperature of cooling water the same as room temperature.
• The machines should be used in an environment, free from external vibration. Do not install machine near a ventilation opening, heat generation equipment or oil mist generating parts.
• This machine uses water. In case of water leakage, please install the machine on the floor with sufficient waterproofing and drainage treatments.
• Please follow the product manual of our company.
