The invention relates to a deformation resisting method for a carburized and quenched thin-walled workpiece. The deformation resisting method for the carburized and quenched thin-walled workpiece aims to solve the problems that when the thin-walled workpiece is carburized and quenched, the thin-walled workpiece is quite prone to deformation and excessive in deformation, so that the thin-walled workpiece cannot meet the drawing requirement after being machined. The deformation resisting method for the carburized and quenched thin-walled workpiece comprises the steps of conducting feeding, and conducting normalization; roughly turning an outer circle, wherein a certain allowance is reserved on each face of an inner hole, and each face of the inner hole is turned flat; conducting tempering; carburizing the inner hole; plating all the surfaces of the workpiece with copper for protection; removing the copper plating layer of the inner hole through sanding; conducting carburization and detection; turning an annular groove; conducting quenching; turning the inner hole; accurately grinding the inner hole; cutting off a right chuck of the workpiece with a wire cutting machine; reserving the allowance of 0.20 mm on each face of the outer circle according to the product drawing of the workpiece and accurately turning other parts; accurately grinding the outer circle and detecting the outer circle; and completing machining. By the adoption of the deformation resisting method for the carburized and quenched thin-walled workpiece, deformation of the product is controlled to be within the required range of the technology and the drawing, the product quality meets the drawing requirement, and the problem that the thin-walled workpiece deforms during carburizing and quenching is solved. The deformation resisting method for the carburized and quenched thin-walled workpiece is applied to the field of machining of the carburized and quenched thin-walled workpiece.
