Abstract

The invention relates to an airflow-assisted abrasive flow polishing method for an internal cylindrical surface. According to the airflow-assisted abrasive flow polishing method for the internal cylindrical surface, the inner wall of a round-pipe-shaped workpiece is polished by means of the combined action of the high-speed rotation of a cylindrical polishing tool and high-speed airflow sprayed out of the cylindrical polishing tool; the rotating speed of the polishing tool is limited to be 500-5000 r / min, and the airflow pressure of the high-speed airflow at airflow outlets is limited to be 0.15-0.6 Mpa; abrasive flow is driven through the airflow at the airflow outlets to a certain extent, and more importantly, the original abrasive flow is promoted through the airflow at the airflow outlets to move irregularly, so that a disordered abrasive flow field which can better facilitate polishing is formed by the abrasive flow, and finally, the effect of removing the inner surface of the workpiece is achieved; the surface consistency is good, and the polishing efficiency and uniformity of the surface of the inner wall of the round-pipe-shaped workpiece are improved.

Description

technical field [0001] The invention belongs to the technical field of fluid surface grinding / polishing, in particular to an inner cylindrical surface airflow-assisted abrasive flow polishing processing method. Background technique [0002] In some special applications in the fields of national defense, aerospace and civil industry, a type of tubular workpiece with a cylindrical surface is required, and the cross-section of the inner wall is circular. The inner surface of this type of workpiece needs to meet higher roughness and surface accuracy requirements , and there must be no processing deterioration layer and subsurface damage, so as to achieve the goals of high precision, stability and high reliability in the actual application process. For the polishing of the inner surface of such workpieces, hard or soft contact processing methods are not suitable because they are easy to cause processing deterioration and subsurface damage, so non-contact abrasive flow processing ...
