Abstract:
A method for grinding surfaces of workpieces using a metal bonded grinding wheel and for sharpening the wheel by electrochemical conditioning comprising the steps of;a) providing an electrode;b) spacing the electrode from a grinding wheel so that a gap is formed between the electrode and the grinding wheel;c) introducing an electrolytic cooling lubricant into said gap;d) passing electrical current through said electrode, through said electrolytic cooling lubricant, and through said grinding wheel;e) pressing a workpiece to be ground against a surface of said grinding wheel and measuring the magnitude of at least one value of a force exerted by the grinding wheel on the workpiece; andf) as a function of a measured value of said force, controlling electrochemical conditioning of the grinding wheel by changing the intensity of the current with a computing and control device.
