Working principle of a grinding machine
The working of a grinding machine: A grinder features an electric motor that supplies motion power to the grinding wheel using a pulley and belt. For the portable grinder, the rotor is inside the grinding machine, and the power switch is located beside the handle of the grinder. So, the switch must be pressed before the grinder works.

Electrochemical Machining (ECM): Process, Working
Electrochemical machining is the reverse of electroplating. An electrolyte works as a current carrier, and the high rate of electrolyte flow in the tool-workpiece gap washes metal ions from the workpiece (anode) before they have a chance to plate onto the tool (cathode). Modification of this process are used for turning, facing, slotting ...

A review of cutting fluid application in the grinding process
Cooling mechanisms. Cutting fluid is applied to the grinding zone to limit the heat generation. The fluid accomplishes this by reducing the amount of friction in the grinding zone through its lubrication properties. It also reduces heat by conducting some of the energy into the fluid instead of the workpiece.
