Description

technical field [0001] The invention relates to a composite processing method and device in the field of mechanical processing, in particular to a solid particle grinding fluid composite processing process and device. Background technique [0002] In ordinary grinding, due to excessive plastic deformation, microcracks, residual stress and surface layer pollution of the surface material of the workpiece due to high temperature and rolling, a surface defect layer will be formed on the workpiece, increasing the surface roughness and waviness. This will affect the fatigue strength, corrosion resistance and contact stiffness of the parts, so that the parts cannot meet the higher service requirements. Therefore, important parts need to be polished after grinding to remove the surface defect layer and reduce roughness and waviness. [0003] According to the enhanced heat transfer theory, the heat transfer capacity of solid is much greater than that of liquid and gas. At room temp...
