The reason why magnetic polishers can achieve sandblasting effects mainly depends on their unique working principle and the interaction of polishing media. The following is a detailed explanation:
1. Working principle
The magnetic polisher uses a magnetic field to drive the polishing media (such as stainless steel needles) to move at high speed on the surface of the workpiece, and removes surface impurities, burrs and oxide layers through friction and impact, thereby achieving a polishing effect. The core lies in the control of the magnetic field, so that the polishing media can act on the surface of the workpiece evenly and efficiently.
2. The role of the polishing medium
The polishing medium is usually a stainless steel needle or a magnetic abrasive. These media rotate and vibrate at high speed under the action of the magnetic field, generating strong friction and impact force, effectively removing impurities and burrs on the surface of the workpiece. The shape and size of the medium can be adjusted according to demand to meet the polishing requirements of different workpieces.
3. Comparison with sandblasting effect
Sandblasting achieves cleaning and roughening effects by jetting abrasives at high speed to impact the surface of the workpiece. Although the magnetic polisher does not directly spray abrasives, the polishing media driven by the magnetic field can also produce similar friction and impact, achieving an effect comparable to sandblasting, especially in fine polishing.
4. Advantages
Uniformity: Magnetic field control allows the polishing medium to act evenly on the workpiece surface to avoid local excessive wear.
Fineness: Suitable for complex shapes and precision workpieces, with a more delicate polishing effect.
Environmental protection: No need to use compressed air and a large amount of abrasives, reducing environmental pollution.
Efficiency: High degree of automation, can handle multiple workpieces at the same time, improving efficiency.
5. Application fields-magnetic polishers achieve sandblasting effects
Magnetic polishing machines are widely used in precision parts, medical equipment, electronic components and other fields, especially for workpieces with high surface quality requirements.
Conclusion
Magnetic polishing machines drive polishing media through magnetic fields to produce friction and impact effects similar to sandblasting, and have advantages such as uniformity, fineness, environmental protection and high efficiency, so they can achieve or even exceed the effect of traditional sandblasting.
