Dorian Tool's Jet-Stream through-coolant system is now designed for both turning and threading applications and is available in multiple (inch and metric) geometries. The coolant system controls coolant volume and pressure with the through coolant Dor-lock clamp and interchangeable coolant nozzles. The coolant stream is aimed at a close range (6 mm) onto the cutting edge of the insert at a high velocity. The controlled stream of coolant lubricates the cutting edge of the insert, thus reducing the coefficient of friction and preventing the chips from adhering to the insert. The physical combination of high velocity and high pressure forces the hot chips away from the cutting edge of the insert. As a result, the insert will operate at a more consistent lower temperature with a clean and undamaged cutting edge, changing the way metal is cut. Higher surface speeds can be achieved with a better surface finish as well as closer working tolerances and higher machine performance, the company says. The insert life can be extended as much as 200 percent.
