Sandvik Coromant adds further options to cooled machining solutions

Additional insert geometries and customised toolholders featuring fixed nozzles have expanded the Sandvik Coromant range of options for applying coolant during the machining process.

In Sandvik Coromant's advanced nozzle technology coolant flows from the pump to the tool through nozzles directed exactly at the cutting zone. This produces a wedge of coolant that efficiently removes the heat from the cutting zone and forms the chip. Improved chip control and longer tool life are just two of the benefits. At low pressure regular toolholders can have a tendency to flood coolant. However, this problem has been tackled in CoroTurn HP holders the high precision nozzles' provide both chip control and process security when machining steel and other common materials. Substantially higher cutting data can also be applied, says Sandvik Coromant. For demanding materials, such as duplex stainless steel and HRSA material, higher coolant pressure is needed. The CoroTurn HP nozzle technology in combination with -SMC, -MMC, - PMC insert geometries is recommended. Few machines provide solutions for pressures in the 150–200 bar range. However, Sandvik Coromant offers standard holders and inserts that allow for up to 275 bar of coolant pressure. Coromant Capto clamping units with 200 bar coolant pressure capability can optimise machine utilisation through reduced set-up and production time. Sandvik Coromant advanced cooling technology has until now been a solution primarily for those employing quick change with Coromant Capto, SL- and QS holding systems. Now, it can be applied with general shank tools, making it possible for everyone working with wet machining to utilise this coolant solution, even in small lathes.
