Magneto-rheological amorphous alloy polishing device, polishing agent and polishing method

Abstract

The invention discloses a magneto-rheological amorphous alloy polishing device which comprises a polishing groove, a fixed clamping device, a motor and a magnetic field generation device, wherein a magneto-rheological polishing agent is stored in the polishing groove; a to-be-polished work piece is fixed in the polishing agent by the fixed clamping device, so that a gap is formed between a polishing face of the work piece and the bottom of the polishing groove; the magnetic field generation device is disposed outside the polishing groove, and an external magnetic field generated by the device makes magnetic particles in the magneto-rheological polishing agent generate rheological effects, so that a magneto-rheological aggregate is formed between the work piece polishing face and the bottom of the polishing groove; and the motor is connected to the polishing groove and can drive the polishing groove to rotate or move back and forth. The polishing device disclosed by the invention has the advantages that a magneto-rheological polishing technology is applied in amorphous alloy polishing; the polishing device applicable to use is provided; an amorphous alloy product can be polished effectively, so that a surface with specular gloss can be obtained; the polishing technology is simple and can be implemented easily; and the polishing device is applicable to large-scale production.

Description

technical field [0001] The invention relates to a polishing device, in particular to a polishing device suitable for amorphous alloys, a polishing method and a polishing liquid used in the polishing device. Background technique [0002] Amorphous alloys are one of the very important research fields in the research and development of new metal materials in recent years. Because there is no regular arrangement of atoms in crystalline alloys, amorphous alloys do not have defects such as grain boundaries, dislocations, and twins of traditional crystal materials. It has many incomparable properties of traditional materials, such as unique electromagnetic properties, mechanical properties, high strength, corrosion resistance, etc. Due to the excellent physical properties of amorphous alloys, many systems of amorphous alloys are widely used in important high-tech fields such as medical device industry, consumer electronics industry, military industry, aerospace and aerospace, and p...

Problems solved by technology

Magneto-rheological polishing technology is now widely used in the polishing process of optical materials. This process has excellent polishing effects on aspheric mirrors. Since strong magnetic fields and magnetically sensitive particles are applied in the polishing process, magnetorheological polishing technology is hardly used. For metal polishing, to prevent the metal from becoming magnetic after polishing and cannot be used in the future
