Optical glass surface grinding machine

Abstract

The present invention relates to an optical glass surface grinding machine applied to the field of glass grinding. When the rotation speed of the front gear belt is equal to the rotation speed of the rear gear belt, the gear plate rotates in place. When the rotation speed of the front gear belt is greater than the rotation speed of the rear gear belt, the gear plate rotates to the left. When the rotation speed of the front gear belt is less than the rotation speed of the rear gear belt, the gear plate rotates to the right. By adjusting the rotation speeds of the front gear belt and the rear gear belt, the gear plate can drive the optical glass to move back and forth on the surface of the grinding plate to grind it.
