Problems solved by technology

The rougher the surface of the aluminum alloy sheet, the worse the wear resistance of the sheet, the faster the wear, the poorer the fatigue strength and corrosion resistance; the surface roughness of the aluminum alloy sheet is generally expressed by the roughness value Ra, and the roughness of the general aluminum alloy sheet surface The degree value Ra is 3.2-6.3, reducing the surface roughness Ra can effectively improve the wear resistance, fatigue strength, corrosion resistance and processing mechanical properties of the aluminum alloy sheet; aluminum used in the manufacture of notebook computer casings, notebook computer keyboards and shafts When using alloy plates, the surface of aluminum alloy plates is required to be smoother, with lower roughness and strong wear resistance. The surface roughness of aluminum alloy plates used in existing notebook casings and shafts is not ideal, and it takes a long time to polish and polish. production time
