We all know that the computer gong processing industry is very popular in the industry, because its performance characteristics in all aspects are more in line with people’s requirements, and the processed effect is also relatively acceptable. Then the computer gong processing aluminum alloy What are the surface treatments?

Surface geometry

① Surface roughness
Refers to the microscopic geometric shape error of the machined surface. In Figure 5-8 (a), R. Represents the arithmetic mean deviation of the roughness profile. The surface roughness is usually formed by the trajectory of the cutting tool in machining, and the ratio of its wavelength to the wave height is generally less than 50.

② Surface waviness
The surface gradient is a periodic geometric error between the macro geometric error (△*) and the micro geometric error (such as roughness). In Figure 58(b), A represents the height of waviness. The surface waviness is usually caused by the low-frequency vibration of the process system during the processing, and the ratio of the wave height is generally 50~l∞.
