Wire wheel and scraper polishing machine have their unique applications in polishing processing, but there are significant differences in their working principle and use. Here's a clear summary of the differences:

How it works:

Steel wheel: mainly through the rotating steel wheel is equipped with a number of small steel wire brush blade cutting metal surface, to achieve the purpose of polishing. Its speed and pressure need to be adjusted according to the metal surface state and requirements to avoid excessive cutting.

Scraper polishing machine: The surface of the object may be polished by a tool similar to a blade, and the specific working principle may depend on the relative movement of the scraper and the surface to be polished to remove the uneven part of the surface and achieve the polishing effect. However, because the specific information of the scraper polishing machine is more limited in the information provided, the description here may not be completely accurate.

Usage and scope of application:

Steel wheel: widely used in the metal industry, suitable for polishing and polishing the surface of steel, alloy, stainless steel, aluminum and other materials. It can improve the gloss and texture of the metal surface, while removing surface burrs, oxides, oil stains, stains and rust.

Blade polishers: May be more suitable for specific types of materials or surface treatment needs, such as blade polishers that are specifically used for polishing during blade processing and are able to deal with uneven blade edges.​

Structure and composition:

Wire wheel: usually composed of a number of small steel wire brush blade fixed on the wheel, driven by the motor to rotate rapidly.

Spatula polisher: May contain a blade or a spatula like tool that achieves the treatment of the polished surface through a specific mechanical structure.

It should be noted that because the description of the scraper polishing machine is not detailed enough in the information provided, the above comparison is mainly based on the characteristics of the wire wheel and the assumed working principle of the scraper polishing machine. In practical applications, different types of polishing machines may be selected according to specific needs and material characteristics.
