Problems solved by technology
[0002] The existing round hole polishing process of sapphire and ceramic workpieces takes a long time and the polishing effect is poor. It is easy to cause the surface finish of the hole to be not up to standard. At the same time, the operator is prone to unpredictable mistakes during the operation process, which affects the further processing of the glass and the quality of the process. Seriously, it will lead to the failure of the workpiece processing, resulting in economic losses of the production enterprise. With the development of the market and the company, the existing sapphire and ceramic round hole polishing process can no longer meet the production and quality requirements.

Embodiment
[0016] A kind of polishing process to the round hole on the sapphire lens comprises the steps:
[0017] (1) First clamp the sapphire or ceramic workpiece to the base of the polishing machine. After clamping, the workpiece can rotate with the technological axis of the hole as the rotating shaft and float up and down at the same time;
[0018] (2) Fill diamond paste as a polishing agent on the inner wall of the hole to be polished in the workpiece;
[0019] (3) Turn on the polishing machine to drive the workpiece to rotate and float up and down. At the same time, the high-speed rotating polishing copper rod above the workpiece moves to contact with the inner wall of the hole of the workpiece to achieve friction polishing.
[0020] Among them, the diamond paste is made of butter, diamond powder, kerosene, and peanut oil in a volume ratio of 7.5:1000:2:1, and the particle size of the diamond powder is preferably 3-10 microns. The material of the polished copper rod is pure copper...

Abstract
The invention discloses a round hole polishing process of sapphire / porcelain. The process comprises the following steps of (1) clamping a sapphire / porcelain workpiece on the base of a polisher; (2) filling diamond paste serving as polishing agent in the inner wall of a hole to be polished of the workpiece; (3) starting the polisher to drive the workpiece to rotate by taking the hole as the process axis at a speed of 25-50 rpm (revolutions per minute) and meanwhile to drive the workpiece to float up and down, moving the polishing copper bar of the polisher to be in contact with the inner wall of the hole of the workpiece and rotating the polishing copper bar at a speed of 300-600 rpm to abrasively polishing the hole of the workpiece. The round hole polishing process of sapphire / porcelain effectively improves the polishing effects, enables the process quality of products to be more stable, improves the product yield and the production efficiency and can be widely applied to industrial production.
