Fragile hollow micro-sphere polishing machine and polishing method

Abstract

The invention provides a fragile hollow micro-sphere polishing machine and a polishing method, and belongs to the technical field of polishing. The polishing machine comprises a working table, a bottom disc, a top disc and an electric control system, and a cavity is arranged at the top end of the working table; the bottom disc and the top disc are arranged inside or above the cavity, and the rotation axis of the bottom disc and the rotation axis of the top disc are both arranged vertically; and the bottom disc and the top disc are driven by a motor; the top disc is arranged above the bottom disc, and at least one vertical through hole used for containing to-be-polished spheres is arranged on the top disc; and the electric control system is electrically connected with the motor and is used for controlling the rotating speed of the motor. The polishing method is used in the polishing machine, the bottom disc and the top disc are rotated at the same time to achieve speed changing and/or direction-changing motion of the to-be-polished spheres, polishing is achieved though relative friction of the to-be-polished spheres at random, the polishing accuracy is higher, and the polishing machine and the polishing method are particularly suitable for fragile hollow micro-spheres with poor mechanical strength.

Description

technical field [0001] The invention relates to the technical field of polishing, in particular to a fragile hollow microsphere polishing machine and a polishing method. Background technique [0002] Polishing machines are electric tools used to polish products, and are widely used. At present, public microsphere polishing machines are mainly disc polishing machines and drum polishing machines. [0003] The disc polishing machine is suitable for the polishing of balls in the bearing production process. When polishing the balls, put the balls of the bearings into the "V" shaped groove that rotates at the bottom, and the top disc is fixed but can apply pressure. It is mainly used for To prevent microspheres from running out of the grinding disc and to control the size and precision of microsphere polishing, it is necessary to inject polishing fluid during the polishing process. This kind of polishing machine is only suitable for microspheres with high mechanical strength. [...

AI Technical Summary

Problems solved by technology

Low-density hollow microspheres will float on the liquid surface of the polishing liquid, making it impossible to polish. Moreover, due to the collision between the grinding aid ball and the ball to be ground, it is impossible to treat the fragile hollow microspheres with poor mechanical strength. to polish

[0005] In the prior art, there is no polishing machine specially for hollow microspheres which are fragile and have poor mechanical strength
