Abstract

PURPOSE: To obtain a lens type body and its similar body having both sides symmetrical with each other by a method wherein after one face of a material retained in an open-close type fitting and removing device is worked, the finished face is sucked and retained in a sucking type fitting and removing device on the same reference shaft line and the other face is worked in the same manner.
CONSTITUTION: A work 27 is retained in an open-close type chuck 10 and a spindle 4 and the chuck 10 are advanced forward respectively and then, a single surface is worked by means of a grinding plate 5 and a polishing plate 6 and thereafter, the spindle 4 is retreated and the chuck 10 is advanced forward. Then, the finished face of the work 27 is attracted to a sucking chuck 11 and next thereto, the chuck 10 is opened and retreated to retain a new work 27. Next, the spindle 4 and chucks 10, 11 are advanced forward and the both works 27 are ground in the same manner simultaneously. With this, a lens type body and its similar body such a crystal oscillator having a small diameter can be obtained in a high accuracy.
