Horizontal super-precision optical lens centering lathe

The invention discloses a horizontal super-precision optical lens centering lathe. The horizontal super-precision optical lens centering lathe comprises a lathe body bracket and a machine tool body arranged on the lathe body bracket; the machine tool body is provided with a spindle mechanism capable of moving and rotating in the Z-axis direction, and a detection mechanism and a turning tool mechanism that can move in the X-axis direction respectively; an X-axis base is fixedly connected to the machine tool body; the X-axis base is provided with X-axis guide rails; an X1-axis slide plate is connected to the X-axis guide rails in a sliding manner; and a probe detecting device for detecting the excircle diameter and the end surface height size of a lens and an optical path detecting device for detecting the optical axis position of a lens on a to-be-processed lens are fixedly connected to the X1-axis slide plate. Through the arrangement of the spindle mechanism capable of moving and rotating in the Z-axis direct
