The application provides an automatic flame polishing method for a quartz wafer, which comprises the following steps: placing a quartz wafer to be polished on a clamp, wherein the clamp comprises a roller provided with a groove, and the edge of the quartz wafer is placed in the groove; controlling a polishing gun to be aimed at the surface of the quartz wafer; and controlling the polishing gun to spray a flame and automatically polish the quartz wafer according to a set moving track while the roller drives the quartz wafer to rotate. Compared with traditional manual polishing, the method has high efficiency, stable polishing, uniform appearance of the polished quartz wafer, and good consistency, so that the processing yield is improved. Moreover, the quartz wafer is driven to rotate by the roller, so that the bumping problem caused by repeated clamping during the polishing process of the quartz wafer is avoided.

This application pertains to the field of diamond polishing, specifically disclosing an apparatus and method for promoting efficient diamond polishing under low-pressure ultraviolet irradiation. The apparatus includes a sealed chamber and an upper rotating shaft, a lower rotating shaft, a polishing plate, and an ultraviolet lamp disposed within the sealed chamber. The sealed chamber contains process gas, and the pressure is maintained between 0.2 torr and 2 torr. The lower part of the upper rotating shaft is connected to the diamond to be polished; the upper part of the lower rotating shaft is connected to the polishing plate. The polishing plate is made of a transparent material or a metal material with multiple light-transmitting holes and is in contact with the diamond to be polished. The ultraviolet lamp is disposed below the polishing plate and coaxially arranged with the upper rotating shaft. This application, by irradiating the diamond to be polished with ultraviolet light under low pressure, enables the diamond to be preferentially graphitized to form a soft graphite layer, which is then removed by friction from the polishing plate at room temperature, effectively preventing damage to the diamond.
