In Grinding, Coolant Application Matters SME
Mar 01, 2008 A dispersed jet pumps air and coolant into the grinding wheel, displacing some of the fluid with air. In some cases the dispersion is so high that much of the coolant hits the workpiece and deflects off. A coherent jet also concentrates its kinetic energy to break through the air barrier and wet the wheel.

Cooling during grinding grindaix GmbH
To stabilize grinding processes and to enable suitable cutting speeds and infeeds, grinding processes on CNC grinding machines are cooled with coolant lubricant. For this, either oils or emulsions (oil + water + additives) are used. Friction is thereby reduced and the process heat is bound in the coolant lubricant.

The synthetic coolants do not transfer heat as well as oils, but the flow possible in grinding applications more than makes up for that. In addition, open grinding such as flat, exposed surfaces throws a great deal of coolant into the air in various size droplets. Oil based coolants are more likely to trap and contain metals and particles.
