High-Pressure Coolant System

Sandvik Coromant (www.coromant.sandvik.com/us) said its new CoroTurn HP high-pressure coolant system offers improved chip control, increased cutting speed and extended tool life in difficult materials when used with Coromant Capto toolholders to harness the high pressure capability of up to 1,100 psi in turning centers, vertical turning lathes and multi-task machines.

Via the turret or spindle, Coromant Capto coupling channels a high pressure coolant jet through small nozzles mounted close to the insert cutting edge. The resulting increase in velocity of the coolant jet produces a hydraulic wedge that lifts the chip from the material, reducing the temperature quickly and effectively while also improving chip control.

CoroTurn HP’s chip control also provides security for unmanned production in turning centers with high volume, automatic component changing, and multi-task machines where chips gathering around the tool prevent automatic tool changing. CoroTurn HP also is said to boost productivity, increasing cutting speed and tool life in roughing up to 20 to 50 percent compared with normal coolant delivery.
