2results about How to "Improve chamfering efficiency" patented technology

The invention discloses a cermet pipe chamfering machine, which comprises a frame, a chuck vertically upwardly installed on the frame and horizontally rotatable, a driving mechanism installed on the frame and used to drive the chuck to rotate, a translation mechanism installed on the frame above the chuck and used to move leftward and rightward, a lifting mechanism installed on the translation mechanism and used to move upward and downward, two extension mechanisms installed on the lifting mechanism and arranged leftward and rightward, the two extension mechanisms being downwardly inclined and oppositely directed, and two grinding wheels respectively installed on the lower ends of the two extension mechanisms. The cermet pipe chamfering machine can improve the chamfering efficiency of cermet pipes and reduce the labor intensity of workers.

The application provides a chamfering tool and chamfering device for a spherical optical element, comprising: a grinding element, the grinding element having a grinding surface, the grinding element surrounding a clearance cavity, and the edge of the grinding surface surrounding an opening of the clearance cavity; a limiting element, the limiting element being arranged on the grinding element, a side surface of the limiting element and the grinding surface surrounding a limiting cavity, the limiting cavity being used for accommodating the spherical optical element, and the lower arc surface of the spherical optical element abutting against the grinding surface. The problem that the spherical optical element with a large concave radius is prone to scratching the polishing surface during the chamfering process on the plane grinding tool is solved.
