Nozzle for Supplying Grinding Electrolyte or Coolant

Improved wettability of an electrochemical or conventional grinding wheel is obtained by supplying the electrolyte or coolant through a divergent nozzle, to overcome an adherent air film on the wheel surface.

During rotation of wheel 1, an air film, typically of few mils in thickness, is continually present close to the surface of the wheel. A conventional nozzle applying electrolyte with a velocity component in the direction of wheel rotation is unable to penetrate the air barrier. However, when nozzle 2 is formed at 3 to direct some of the electrolyte opposite to wheel surface motion, the momentum of the electrolyte, being considerably greater than the momentum of the air, is able to penetrate and dislodge the air barrier.

Electrolyte issuing from the lower portion 4 of the nozzle is then able to establish more intimate contact with the wheel surface and fill the space between the wheel 1 and workpiece. The result is a superior flatness tolerance, more consistent cuts and improved electrochemical action.
