The analysis of the interaction of the abrasive wheel working fluid with the treated surface when grinding wood and wood materials

Abstract

In the mechanical technology of wood, a large amount of work falls on grinding operations, which are final in the manufacture of parts before finishing or gluing. The flow of these technological operations, the appearance and quality of products depends on the roughness of the polished surface. The use of abrasive wheels made of spherecorundum increases the productivity of the process of abrasive machining of parts. The field of application of hard abrasive tools for grinding wood and wood materials is expanding due to the reduction of tool salting and the elimination of burn-in of the treated surface. In the manufacture of an abrasive tool, the characteristics of the internal volumetric structure are regulated - granularity, grain content and ligaments. When grinding wood and wood materials, only the peripheral surface of the circle, its relief, takes a direct part in the work. The paper describes the relief of a circle made of spherecorundum and establishes a relationship between volumetric characteristics and its surface geometric parameters, which are necessary to determine the main indicators of the grinding process.
