  The application of HIPRECO is very suitable for the processing of general hard cutting and machining materials, including atomic energy plant construction materials, aerospace construction materials and advanced energy producing plant construction materials.
  We would like to enhance the productivity of material cutting, machining and processing works at a stretch with accuracy and speed ・・・・
In order to satisfy the above requirements, it is prerequisite to adopt the spindle-through ; High Pressure Coolant (HPC). If not, there would be a great difference of productivity and accuracy between the use of HPC and no-use of HPC.
  ① High-performance plunger pump is installed (Advanced tyoe high-pressure pump is used. Then a great deal of water discharge can be realized).
  As one of leading pump manufacturers in Japan, the manufacturer has manufactured high-pressure pumps provided with more than 7.0MPa pressure, by accumulating long-experienced know-how. As a matter of fact, the pump featured highly endurable and stabilized properties. U-HIPRECO-185 Type is a global standard type (cope with all waters used world widely).   ※ SUS316 materials are used for pump wetted parts.
  ② High micro dust can be filtered by a precision type filter:
  Exclusively designed filter-less cyclon filter is used. When floating carbon dusts or micro particles are many, the Skimmer can recover such harmful matters. As a result, the abrasion of cutting tools can be protected. successfully (Option).
  ③ Motors can be controlled in proportion to the liquid flow rate loading.  
  In proportion to the liquid discharge amount from the high-pressure pump, the motor speed can be controlled automatically. As a result, energy-saving and CO2 emission reduction from environmental areas can be made successfully.
  Proposal of High Pressure Coolant (HPC) unit according to a high-pressure coolant unit.
  Accompanied with the recent environmental variations, advanced requirements are required alongside by the industrial needs. クーラント噴射

  Experiments of High Pressure Coolant (HPC) conducted by using HIPRECO.
  Test materials of “Inconel 718 43HRc” were experimentally cut and machined for 3 minutes. Then chips thus obtained were examined mainly for their shape.
Normally the test materials are cut and machined by applying normal coolant pressure at least for 3 minutes.
The test materials are cut and machined by using the High Pressure Coolant (HPC) unit by applying 230 bar pressure at least for 3 minutes.
  The test materials of “Inconel 718 43HRc” were experimentally cut and machined by applying 150br and 300br of coolant pressure, and then, cutting chips were obtained.
Coolant pressure 150br
Coolant pressure 300br
  Abrasion loss of a cutting tool tip elapsed by the normal use of Titan (Ti-6AI-4V) material by applying normal pressure and by applying HPC.
