剪板機機床的剛度指機床在外力作用下反抗變形的能力，機床的剛度越大，動態精度越高。機床的剛度包含機床構件自身的剛度和構件之間的觸摸剛度。機床構件自身的剛度首要取決于構件自身的資料性質、截面形狀、大小等。構件之間的觸摸剛度不僅與觸摸資料、觸摸面的幾何尺寸和硬度有關，并且還與觸摸面的表面粗糙度、幾何精度、加工方法、觸摸面介質、預壓力等要素有關。

The stiffness of the plate shearing machine tool refers to the ability of the machine tool to resist deformation under the action of external forces. The greater the stiffness of the machine tool, the higher the dynamic accuracy. The stiffness of machine tool includes the stiffness of machine tool components themselves and the touch stiffness between the components. The stiffness of the machine tool component itself mainly depends on the data nature of the component itself, the shape of the section, size and so on. The touch stiffness between components is not only related to the touch data, the geometric size and hardness of the touch surface, but also related to the surface roughness, geometric accuracy, processing methods, touch surface media, pre-pressure and other factors of the touch surface.
