Composite polishing machine tool and machining method thereof

Abstract

The invention relates to a composite polishing machine tool and a machining method thereof. The composite polishing machine tool comprises a six-joint robot. The bottom of the six-joint robot rotates on a base. A drive device is connected to the operation end of the six-joint robot. A polishing operation mechanism comprises an airbag polishing mechanism and a numerical control polishing mechanism. The connecting end of the airbag polishing mechanism or the numerical control polishing mechanism is detachably connected with the drive device through a hydraulic expanding cover. A polishing table is arranged within the operation range of the operation end of the six-joint robot. An optical element is fixed to the top of the polishing table. The polishing operation mechanism is connected to the outer contour of the optical element in an abutting-against manner. A polishing liquid circular filtering device is arranged close to the polishing table and used for providing clean polishing liquid for the optical element continuously in the polishing process. The polishing technology procedure is preset and / or arranged in a control terminal online. The six-joint robot, the drive device and the polishing liquid circular filtering device are electrically connected with the control terminal. Universality of the machine tool is achieved, and the machining precision and the machining effect of the optical element are improved.
