Combined electromachining method for bamboo-like micro-structure of rotating body inner surface

Abstract

The invention belongs to the field of electromachining and provides a combined electromachining method for a bamboo-like micro-structure of a rotating body inner surface. The method includes the following steps that 1, a hollow aluminum rotating body, a hollow copper rotating body and an aluminum core model (3) are manufactured; 2, aluminum ring slices (1) and copper ring slices (2) are machined; 3, the proper aluminum ring slices (1) and the copper ring slices (2) are selected according to the bamboo-like structural morphology, required to be manufactured, of the rotating body inner surface to be embedded into the aluminum core model (3) according to the aluminum-ring-copper ring multi-layer interval sequence; 4, electric copper casting machining is carried on the aluminum core model (3) where the aluminum ring slices (1) and the copper ring slices (2) are embedded, and an electric casting (4) is obtained; and 5, the electrically-cast rotating body is cleaned, aluminum materials are removed through an alkaline solution, and the bamboo-like micro-structure (5) of the rotating body inner surface made of copper is obtained. By means of the combined electromachining method, high-precision machining of the bamboo-like micro-structure of the rotating body inner surface is achieved.

Problems solved by technology

Milling processing generally cannot meet the size requirements of micro-narrow grooves, and even if micro-milling is used, deformation and burrs of micro-ribs between adjacent narrow grooves cannot be avoided; laser processing can achieve micro-sized processing, but there are metamorphic layers and micro-scales on the processed surface. Cracks, severe deformation of micro ribs
