The difference between flat polishing machine and magnetic polishing machine
A flat polisher is a mechanical device used to polish and grind flat surfaces. It usually consists of a rotating flat polishing disc and an electric motor to control the speed and trajectory of the disc. Surface polishers can be used to treat surfaces of different materials such as metal, plastic, ceramic, stone and glass. In the industrial field, flat polishing machines are widely used in the manufacture and processing of precision components, such as optical lenses, silicon wafers and micro-electromechanical systems. In addition, they can be used in areas such as laboratory research, material analysis and geological sample preparation.
Flat polishers and magnetic polishers are both surface polishing and grinding machines , but there are some differences between them.
First of all, flat polishing machines are mainly used for processing flat surfaces, while magnetic polishing machines are more suitable for polishing and grinding irregular surfaces such as curved surfaces, cylinders, and spherical surfaces.
Secondly, the flat polishing machine achieves surface processing through the rotating flat polishing disc, while the magnetic polishing machine absorbs the workpiece through the magnetic field generated by the electromagnet, making it in close contact with the abrasive material for polishing and grinding.
In addition, magnetic polishing machines usually use abrasives and abrasive fluids, while surface polishing machines mainly use abrasive paper and abrasive fluids.
The difference between flat polishing machine and magnetic polishing machine is as follows:
The working principle is different: the surface polishing machine achieves surface polishing and grinding by rotating the polishing disc and applying pressure to the sample, while the magnetic polishing machine uses a magnetic field to control the movement of abrasive particles on the surface of the sample to achieve surface polishing and grinding.
Different application fields: plane polishing machines are usually used to process larger and thicker samples, such as metal sheets, plastic sheets, etc.; while magnetic polishing machines are more suitable for processing small, thin-walled, thin-film samples, such as semiconductor devices, precision machinery parts etc.
The polishing effect is different: flat polishing machines are suitable for surface polishing and grinding that require high precision and flatness, but are slower when removing large amounts of material. While the magnetic polishing machine can quickly remove material, but the polishing accuracy and flatness are relatively low.
The polishing method is different: the polishing method of the flat polishing machine is mechanical collision grinding, which needs to use abrasive grains or polishing sheets for surface polishing and grinding; while the polishing method of the magnetic polishing machine is to control the trajectory of the abrasive grains in the magnetic field. Substances such as polishing sheets or abrasive grains are required for surface polishing and grinding.
Since magnetic polishers hold workpieces and abrasive materials together through a magnetic field, they are more suitable for processing small and thinner workpieces, while flat polishers can handle larger and thicker workpieces.
