Tokupi Co., Ltd.　高圧クーラントユニット

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.

●Cost reduction
●Stabilization of quality
●Energy saving

In order to satisfy the above requirements, we have developed an advanced spindle-through type High Pressure Coolant (HPC) unit.

Merits obtained from the use of the HPC

•Elevation of cutting speed
Improvement of production efficiency and elevation of productivity
•Reduction of cutting tool abrasion
Elongation of cutting tool service life time and reduction of cutting tool costs
•Stabilization and elevation of quality accuracy
•Energy saving
Control of output control in proportion to the flowing load
•Decrease of CO2 emission into the atmosphere by reduction of machining/processing time

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.
