For studying the effect of different heat treatment states on the chemical milling properties of 2195 Al-Li alloy, orthogonal experiments were used to research the chemical milling properties of 2195 Al-Li alloys with different heat treatment states(T8 state and O state) under different process parameters. Results showed that the chemical milling rate in T8 state was higher than that in O-state under different process parameters, and the side cutting rate in T8 state was more stable than that in O-state. Meanwhile, the surface quality of 2195 Al-Li alloy after chemical milling was related to the heat treatment state. The O-state sample had different degrees of etching grooves at the rib position after chemical milling, while the T8-state sample was smooth and flat and had better surface quality after chemical milling.
