Magnetism: the magnetic system used in the magnetic polishing of medical device accessories allows the workpiece to rotate steadily in a magnetic field while holding the abrasive material on the surface of the disc to form an abrasive layer. In this way, the surface of the workpiece can be covered by and acted upon by the abrasive, and the magnetic polishing machine keeps the workpiece fixed by the powerful magnetic system.
Abrasives: abrasives are one of the keys to magnetic polishing of medical device parts, and the abrasives used in magnetic polishing machines are generally stainless steel needles and other hardness abrasives. When polishing, the abrasive constantly interacts with the surface of the workpiece, so that its surface burrs and imperfections are gradually smoothed, thus improving the surface finish and quality. The finer the grain size of the abrasive, the better the polishing effect, but the polishing time will be extended accordingly.
Friction: When the workpiece rotates in the magnetic field, it is subjected to the action of the abrasive material, which generates friction and gradually smoothes out the burrs and oxidised skin on the surface of the workpiece until the surface reaches the required finish. When the workpiece and the abrasive interact, a frictional force is generated which smoothes out burrs and imperfections on the surface of the workpiece. At the same time, the rotation of the magnetic system helps to provide even contact with the abrasive on the surface of the workpiece, resulting in a more uniform and consistent finish.
The principle of magnetic grinding and polishing of medical device accessories is to use the friction between the magnetic force, abrasive and workpiece surface to remove burrs and imperfections on the surface of the workpiece, so as to improve its surface quality and finish. This approach ensures that the surface quality and health and safety of medical device fittings are in line with relevant medical industry standards and requirements.
During the manufacturing process of medical device parts, it is often necessary to polish the surface to achieve a high degree of finish and sterility requirements, magnetic grinding and polishing machines can efficiently complete this task.
