Abstract
A method of grinding includes the application to an abrasive wheel in a grinding zone of a pulse voltage, arranged out of the grinding zone is an electrode to which is applied a rectified voltage having an amplitude and a ripple factor ensuring formation of an oxide film on a surface of the wheel, and use is made of a coolant having a conductivity from 2.multidot.10.sup.-3 to 2.multidot.10.sup.-2 ohm.sup.-1 cm.sup.-1.
Claims4
A method of abrasive electroerosion grinding with the aid of a metallic-bond abrasive wheel and a coolant having a conductivity of from 2.multidot.10.sup.-3 to 2.multidot.10.sup.-2 ohm.sup.-1 cm.sup.-1, comprising the steps of:
- applying a pulse voltage to said wheel in a zone of grinding;
- arranging an electrode adapted to produce an additional electric effect on said wheel out of said zone of grinding of said workpiece;
- creating an interelectrode space betwen the electrode and wheel for a coolant to be supplied thereinto;
- applying a rectified voltage having an amplitude and a ripple factor to said electrode and wheel, which ensures formation of an insulating oxide film on the surface of said wheel.
