Improved chip control and extended tool life are two key benefits of Sandvik Coromant ’s new CoroTurn HP high pressure coolant system.

This coolant system is a unique combination of Coromant Capto and CoroTurn HP (high pressure) design that harnesses the machining possibilities afforded by high pressure coolants which lead to increased productivity or as much as 50% increased tool life in some materials.

The Coromant Capto coupling channels the coolant through the turret or spindle and accurately positions it on the spot that many need it (not possible using shank tool holders).

This new coolant system can be used in any machine equipped with high pressure coolant and Capto coupling, including multi-task machines, vertical turning lathes (VTL) and turning centres.

CoroTurn HP penetrates the heat affected zone via a high pressure coolant jet delivered through small nozzles to cool the insert faster, more effectively and allow optimal chip control.

The jet creates a hydraulic wedge between the top surface of the insert and the underside of the chip being removed from the component or material, helping to reduce insert wear and break the chip into smaller pieces for quicker evacuation from the cutting edge.

The nozzles, mounted closer to the insert cutting edge, help increase the velocity of the coolant jet at lower pressures and keep the insert freely accessible for easy indexing.

In roughing, because chip control is not normally a problem, applying the coolant precisely in this way reduces the cutting temperature and allows either increased tool life or increased cutting speed in all materials.

Finishing operations always present more problems in chip control owing to their reduced depth of cut and feed rate.

Automated production, whether high volume mass production or using multi-task machines and vertical turning lathes with automatic tool changing, cannot afford to allow chips to gather around the tool as this could cause costly machine stoppages.

The unique Coromant Capto and CoroTurn HP system provides total chip control and therefore security for unmanned production.

The overall result is improved productivity through use of increased cutting data, for example, as much as a 50% increase in cutting speed, or improved surface finish with the same number of components/material machined.
