Technical content
Support for dicing quality The DTU162 keeps both spindle cooling water and cutting water at a constant temperature and suitable pressure. It thereby helps manage expansion, contraction, and other undesirable phenomena caused by water temperature fluctuation. Reduced environmental impact By circulating used cutting water and precipitation filtration of water- borne debris, the DTU162 significantly reduces water consumption and environmental impact. Further, the refrigerant used in DTU162 is a completely non-ozone-depleting hydrofluorocarbon (R-407C). DTU162 Higher Dicing quality with lower environmental impact Small footprint The efficient design of DTU162’s interior makes a very small unit footprint possible . Diagram of cutting water flow Water Temperature Control Unit Easy maintenance Use of long 20’’ filters allows for less frequent replacements. Interior layout designed for maximum the simplicity of regular maintenance.

- Use clean, oil-free air at a dew point of -15 ℃ or less. (Use a residual oil: 0.1ppm. Filtration rating: 0.01 µm/99.5 % or more).
- Keep room temperature fluctuations within ±1 °C of the set value. (Set value should be between 20 - 25 ℃).
- Keep cutting water and cooling water at the same (within ±1 ℃ fluctuations) temperature as the room.
- Use water that has a specific electric conductivity greater than 1 µS for cutting.
- 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. * All the pressures are described using gauge pressures. * The above specifications may change due to technical modifications. Please confirm when placing your order. * For further information please contact your local sales representatives 2014.11
