Nanofluid as coolant for grinding process: An overview ...

2018-4-6  In grinding process, coolants are used to improve the surface finish, wheel wear, flush the chips and to reduce the work-piece thermal deformation. The conventional cooling technique, i.e., flood cooling delivers a large amount of fluid and mist which hazardous to the environment and humans. Industries are actively looking for possible ways to ...

In Grinding, Coolant Application Matters

2008-3-1  I use a flow rate based upon the grinding power created during the process, because the more aggressive a cycle is, the more coolant is applied. With conventional abrasive wheels, a flow rate of 2 gpm/hp is effective. For superabrasive wheels, a flow rate close to 1 gpm/hp (3.8 L/min/hp) works well.

Understanding Grinding Fluid - Canadian Metalworking

2011-10-25  Because the grinding process creates a lot of heat, flood coolant is most appropriate. However, it is equally important that the fluid be delivered where it is needed the most: at the point of cut. “The application [method] of the fluid is very important; it should apply the fluid to the interface where it is needed the most,” said Foster.
