High Pressure Coolant (HPC)
Using HPC results in shorter chips which can be easily
evacuated. The unique coolant nozzles designed for
70 bar (1000 psi) make it possible for the coolant to be
directed precisely at the cutting edge.
Due to the precise direction of
the coolant flow, the HPC cutting
heads can be utilized for benefits
even at lower pressure.
The flow and volume of
coolant becomes impor-
tant to evacuate chips
out of deep bores when
machining long overhangs.
Several nozzles increase the
volume of the coolant
Coolant can be applied through the rear of the boring
bar using common size connectors with British Standard
Pipe (BSP) threaded fittings. Sandvik Coromant
dampened boring bars are equipped with a pre-threaded
coolant intake hole D
