The invention belongs to the technical field of wood processing, and particularly relates to a prediction method and a prediction model for the press ball hardness of a chord-cut processing surface of heat-treated wood, and the prediction method comprises the following steps: selecting a raw material, cutting the raw material into raw material wood, and measuring the press-in load P0 of the surface of the raw material wood; the raw material wood is subjected to heat treatment at the temperature T, and heat-treated wood is obtained; the press-in load P prediction of the selected chord cutting machining face of the heat treatment wood is predicted, and the press ball hardness HR prediction of the chord cutting machining face is calculated and predicted. According to the prediction method and the prediction model for the press ball hardness of the chord-cut processing surface of the heat-treated wood, the change of the press ball hardness of the chord-cut processing surface of the heat-treated wood at 160-220 DE
