DEVELOPMENT OF A SETUP FOR VIBRATORY ABRASIVE TREATMENT OF SURFACES OF DECORATIVE ELEMENTS WITH AN ACTIVE WORKING TOOL

Abstract

This work provides an overview of equipment and technologies for decorative-finishing treatment of parts. It is established that the most effective methods are abrasive mechanical processing techniques such as tumbling, vibrational, centric-rotational, and centric-planetary. Each of them exhibits varying levels of efficiency in specific application areas. Currently, these methods ensure the highest processing efficiency and quality while maintaining the lowest product cost and manufacturing complexity. Technological equipment is currently produced in series, which may include relatively complex assemblies and mechanisms to address complex technological process tasks, each having specific drawbacks. The main directions for improving equipment are identified, and a classifier of part characteristics for vibro-processing is provided to standardize and unify. Structural schemes for setups for vibratory abrasive processing with actively positioned horizontal and vertical working tools are proposed. The uniqueness of these setups lies in the ability to create vibrational fields of different intensities (controlled vibratory exciter of the working chamber) and to control the intensity of the motion of the working tool. Control over these parameters allows adapting the setup to a specific technological process and achieving optimal technical and economic indicators for vibro-processing parts, especially for decorative elements with complex shapes, small dimensions, diverse material characteristics – varying hardness and viscosity, which may pose challenges with conventional methods.
