Ultra high pressure coolant unit.

High pressure breaker./Ultra high pressure coolant unit.

高圧クーラント/ハイプレッシャーブレーカー

New machining technology that breaks down the conventional high pressure coolant concept.

The chip shredding system HPB (high pressure breaker) that uses the ultra-high pressure coolant , prevents the entangement of chips and greatly improves the production efficiency.Also, when machining heat-resistant steel, under normal coolant conditions, chips interfere with the coolant reaching the cutting point, as a result, heat accumulates at the cutting edge. But it improves by injecting ultra-high pressure coolant to the cutting edge.

Features and benefits of HPB.

Equipped with high-performance high-pressure plunger pump

A high-performance high-pressure pump that can be used in harsh environments.
Ceramic is used for the plunger
超純水ポンプ

The fine ceramic plunger has less wear, which makes the packing last longer.

Easy maintenance

Replacement and maintenance of consumable parts (seals, packing, etc.) is easy.

COUTION

When using the pump, be sure to add oil to the crank chamber before operation.
Use "Engine oil SAE10W-30" or "Industrial lubricating oil ISO VG100-150 grade"
Hydraulic fluid cannot be used.

Built-in high-precision filtration device

No need to replace the cartridge filter.Uses a filterless (high-precision cyclone separator) method.
hpb_cyclon

By controlling a high-precision cyclone separator, the flow of fluid into the clean tank at the start / stop of supply with unstable filtration accuracy (acceleration / deceleration of the supply pump flow rate) is cut.
