The invention provides a composite material winding regenerative cooling thrust chamber and a machining process, and relates to the field of liquid rocket engines. The composite material winding regeneration cooling thrust chamber comprises a thrust chamber body and a composite material layer. A cooling groove is formed in the outer side wall of the thrust chamber body; the composite material layer is arranged on the thrust chamber body in a sleeving mode, the composite material layer wraps the cooling groove to form a cooling channel, and the composite material layer is formed by winding composite fibers on the thrust chamber body. The outer side wall of the thrust chamber body provided with the cooling groove is equivalent to an inner shell of a sandwich structure, and the composite material layer arranged on the thrust chamber body in a sleeving mode is equivalent to an outer shell of the sandwich structure. Due to the fact that the composite material layer is formed by winding the composite fibers on the
