Description
Summary:In the manufacture of small-sized parts, the finishing of the internal channels of a complex cross-section with a coating is particularly difficult. To solve this problem, it is proposed to use centrifugal processing with steel balls in containers with planetary rotation. The paper presents the results of computer simulation of the contact interaction of balls with the surface of the part channel. These data made it possible to establish that at certain velocities and directions of the flight vector at the moment of contact, the balls allow you to remove the micro-roughness of the coating without violating the integrity of the part base. The simulation results formed the basis for the design of an industrial installation and the assignment of centrifugal-planetary processing modes. The proven technology of finishing the internal channels of small-sized details provided a reduction in the proportion of damaged parts by 4...4.3 times relative to the basic technological process.
