Machining process for guide shoe of high-speed radial tilting pad supporting bearing

The invention belongs to the technical field of bearing machining, and particularly relates to a machining process for a guide shoe of a high-speed radial tilting pad supporting bearing. The invention relates to a machining process for a high-speed radial tilting pad supporting bearing guide shoe. The machining process comprises the following specific steps: a, blanking a shoe blank; b, thermal refining; c, rough turning; d, dehydrogenating and annealing; e, tinning; f, bearing alloy is poured; g, stress relief heat treatment; h, rough turning; i, finish turning of an outer circle; j, tile cutting; and k, inner hole machining. According to the technology, rough turning and finish turning are conducted on a tile blank subjected to stress relief heat treatment, then cutting is conducted, and due to the fact that the tile blank which is not cut is of an integral annular structure, cutting is conducted on the tile blank firstly, and the accuracy and the surface roughness of the machining size of the tile and the
