VERFAHREN ZUM HERSTELLEN EINES PIEZOELEKTRISCHEN BAUTEILS

摘要

The method involves flowing an electric current, when the material of one exterior surface (14,14~) is removed between the medium (28) and a unit interval. An electric tension is applied in one electrode (18) and the electric current flowing is measured, when the material is removed by one electrode. The removal of the material in unit interval occurs by loops with an abrasive.
