Advanced cooling technology
The Sandvik Coromant advanced cooling technology is a unique
concept that optimizes the use of coolant in all wet machining. By
directing the coolant with precision to the cutting zone, the
generated heat is efficiently removed from the cutting zone, giving
excellent chip breaking, also in difficult materials, regardless of
what pressure you use.
• When using low pressure (up to ~30 bars/435 PSI) – the
Sandvik Coromant HP holders will outrun regular tool holders
thanks to the exactly directed coolant jets
• When using high pressure (above 30 bars/435 PSI), the most
productive solution is a combination of the Sandvik Coromant HP
holders and insert geometries dedicated for high pressure
coolant. The higher the pressure, the more demanding materials
can be machined with excellent results. Sometimes a high
coolant flow is required to wash the chips from the bore.
Silent Tools adapters are designed for 70 bars (1015 PSI) pressure
with the exception of the diameter 100 mm (3.94 inch) boring bar,
which has a capacity of 50 bars (725 PSI).
