Abstract: This paper mainly introduces the advantages, principles and practical applications of Magnetic polishing machine in 6061 aluminum alloy processing, and analyzes the important role of magnetic polishing machine in improving the surface quality of 6061 aluminum alloy and reducing production costs.

I. Introduction

6061 aluminum alloy has been widely used in aviation, aerospace, automobile, electronics and other fields due to its excellent mechanical properties, good corrosion resistance and high machinability. However, in the processing of 6061 aluminum alloy, surface quality has become a key factor restricting product quality. As a new type of surface treatment equipment, magnetic polishing machine has the advantages of high efficiency, environmental protection and energy saving, and gradually emerged in the field of 6061 aluminum alloy processing.

II. Principle of magnetic polishing machine

Magnetic polishing machine uses the effect of magnetic abrasive in magnetic field to grind and polish the workpiece. Its main principles are as follows:

Magnetic field generation: The magnetic polishing machine has a built-in strong magnetic field, which makes the magnetic abrasive generate magnetic lines in the magnetic field.

Magnetic abrasive adsorption: Under the action of the magnetic field, the magnetic abrasive is tightly adsorbed on the surface of the workpiece.

Grinding and polishing: Magnetic abrasives move at high speed in a magnetic field to grind and polish the surface of the workpiece.

Cleaning and separation: During the grinding process, the abrasive and the workpiece surface are worn and the abrasive gradually becomes smaller. The worn abrasive is separated from the workpiece through the cleaning device to ensure the polishing effect.

3. Advantages of magnetic polishing machine in 6061 aluminum alloy processing

Improve surface quality: The magnetic polishing machine uses magnetic abrasives to grind 6061 aluminum alloy in an all-round and uniform manner, effectively removing defects such as burrs and oxide scales, and improving surface roughness.

Save manpower and material resources: The magnetic polishing machine has a high degree of automation, and one person can operate multiple devices, saving manpower and material costs.

Environmental protection and energy saving: The magnetic polishing machine uses water-based abrasives, and no chemical agents need to be added to reduce environmental pollution. At the same time, the equipment has low power consumption and significant energy-saving effects.

Strong adaptability: The magnetic polishing machine can adjust the magnetic field strength, abrasive type and grinding time according to the shape, size and polishing requirements of the workpiece to adapt to different working conditions.

IV. Practical application cases

An aviation parts manufacturer uses a magnetic polishing machine to perform surface treatment on 6061 aluminum alloy parts. After treatment by the magnetic polishing machine, the surface roughness of the parts is improved from Ra1.6 to Ra0.4, and there are no obvious scratches, burrs and other defects. At the same time, production efficiency is increased by 30% and labor costs are reduced by 50%.

V. Conclusion

The application of magnetic polishing machines in the processing of 6061 aluminum alloys effectively improves the surface quality of workpieces, reduces production costs, and has broad market prospects. With the continuous development of my country's manufacturing industry, magnetic polishing machines will play an important role in more fields.
