Abstract

PURPOSE:To make it possible to mass-produce a lens type crystal vibrator with any sphericity by turning a cylindrical drum body which contains hermetically crystal plates and abrasives. CONSTITUTION:As cylindrical drum body 4 rotates, many crystal plates 1 installed in drum body 4 together with abrasives 5 are turned over and over being polished by the flank of drum body 4, and consequently both the sides of each crystal plate 1 agree with the flank of drum body 4 in terms of sphericity, so that lens type crystal vibrator (a) with sphere 7 will be manufactured. Then, a lens body with any sphericity can be obtained by changing the radius, i.e., sphericity of drum body 4. Thus, uniform lens type vibrators can be mass-produced.
