Viscosity-controllable abrasive particle flow polishing method and device

Abstract

The invention discloses a viscosity-controllable abrasive flow polishing method and device. The method comprises the steps: adding polishing abrasive particles, a dispersing agent, a thickening agent and other additives into a molten mixed solution of solid paraffin and liquid paraffin, and forming a polishing viscous liquid; wherein the mass percent of the solid paraffin is 50-90%; the mass percent of the liquid paraffin is 0-20%; the mass percent of the polishing abrasive particles is 5-30%; the mass percent of the dispersing agent is 0.5-2%; and the mass percent of the thickening agent is 0.2-2%. Meanwhile, the invention discloses a device for achieving the polishing method; in the polishing process, a temperature regulator is used for heating the paraffin solid for polishing to the softening point to form polishing mucus; a machined part and the polishing mucus are driven to do relative motion, and the viscosity of the polishing mucus is adjusted by controlling the temperature of a polishing groove; the holding force of abrasive particles in the polishing mucus is changed; and efficient and precise polishing of the surface of the machined part is achieved. Efficient ultra-precision polishing of a revolving body part can be achieved by adjusting the viscosity of a polishing medium.

Description

technical field [0001] The invention belongs to the technical field of ultra-precision polishing, and in particular relates to a viscosity-controllable abrasive flow polishing method and a device thereof, in particular to an abrasive flow polishing method and a device of a revolving body part. Background technique [0002] Rotary parts are widely used in the fields of daily necessities, machinery industry, aerospace and military weapons. For example, thermos cups and rice cooker liners in daily life, bearing roller elements and hydraulic switch shaft elements commonly used in the industrial field, and aspheric mirrors used in the aerospace and military fields are all typical rotary parts. Among them, the insulation cup and rice cooker must be polished before electroplating to ensure the quality of the coating; the bearing rollers and balls must be evenly polished to a smooth surface to prolong the service life of the bearing; the aspheric mirror must be polished to an ultra-...

AI Technical Summary

Problems solved by technology

Due to the different forces between abrasive grains and parts in different processing stages, it is difficult to adapt to the requirements of different polishing precision for the fixed-viscosity polishing medium obtained from a single formula.

[0005] In summary, the existing fluid polishing technology is difficult to achieve high-efficiency ultra-precision polishing of rotating parts at low cost
