Brush Polish application

1、 Overview of brush polishing
1. What is brushing
Brush polishing refers to the process of processing the surface of parts on the brush polishing machine or manually with the brush wheel made of metal wire, natural or man-made fiber and animal hair. Brush polishing can generally improve the surface roughness by 0.5-1, and the effect on size is 0.5-1 μ M does not affect the geometric accuracy and will not change the geometry of the part. Wet or dry brush. During wet brush polishing, water is generally used as brush polishing solution. For black metal brush polishing before plating, in addition to water, if decontamination is required, cleaning agent with degreasing function should be used.
3. Brush Polish application
2.1 surface cleaning
Brushing is mainly used to clean the oxide scale, rust, old paint layer, welding slag and other dirt on the surface of parts, as well as the residual floating ash after the parts are eroded.
2.2 deburring
Remove the burrs on the edges of the machined part surface by brushing.
2.3 silk brush
Brush a certain regular and fine silk pattern on the surface of the parts, such as wavy pattern, fish scale pattern, etc., to achieve the purpose of decoration.
2.4 satin finish
Satin finish is the process of using a soft and fine brush wheel to brush the part surface into a Matte Satin diffuse reflection layer, which can make the part surface obtain a non mirror like flickering luster.
3. Brush principle
The elastic metal wire on the brush wheel has good cutting and scraping ability. Therefore, the brush wheel or brush is actually a multi edge cutting tool, and each brush wire can be cut. In the processing process, through the relative movement of the brush and the workpiece (linear reciprocating motion or rotary motion), with the help of the brush wire to repeatedly crimp, friction, cutting and elastic impact on the workpiece, the rust, dirt, edges and burrs on the metal surface can be removed, or the decorative bottom processing can be carried out on the basic surface of the parts, such as silk brushing, satin finishing, etc.
4. Application industry
In recent years, various brush wheels have been widely used in hydraulic, pneumatic, machine tool, electrical, food, light textile, aerospace and other industries.
