Abstract

A method for processing a lens barrel includes the steps of: (a) providing a processing device including a processing shaft and a cutting tool; (b) moving the lens barrel and the processing shaft relative to each other so that an image of the cutting tool projected on a plane that intersects a tubular wall of the lens barrel is orthogonal to the tubular wall; (c) moving the processing shaft relative to the lens barrel so that the cutting tool is close to the tubular wall; (d) moving the processing shaft relative to the lens barrel so that the cutting tool is in touch with the tubular wall; (e) moving the processing shaft and the lens barrel relative to each other so that the lens barrel is formed with a continuous groove on the tubular wall; and (f) moving the cutting tool away from the lens barrel.
