Abstract

The invention discloses a detachable soft gasket and method for thin plate grinding deformation control. The soft gasket structurally comprises a friction adsorption enhancement layer, a micropore vibration reduction layer and an elastic supporting layer which are detachably connected in sequence from top to bottom. In the soft gasket, the elastic supporting layer provides flexible buffering, the micropore vibration reduction layer absorbs machining vibration through a closed-cell micropore structure, the friction adsorption enhancement layer enhances the adsorption force and stability through non-uniform waveform raised grains and conical grooves, the bottom of the friction adsorption enhancement layer is designed in a sealed mode, grinding fluid permeation is effectively prevented, and all the layers cooperate with one another to improve the machining precision. The soft gasket is designed to be of a multi-layer structure, machining deformation is effectively reduced by providing a positioning reference, and the problems of initial deformation, end face jumping and planeness out-of-tolerance of the thin plate caused by a traditional rigid fixing or adsorption mode can be remarkably solved.
