A TOOL FOR GRINDING PROFILED WOOD PRODUCTS AND WOOD MATERIALS

Abstract

Grinding is one of the methods of mechanical processing of wood with a multi-cutting tool with an unorganized geometry - a grinding wheel. The main purpose of the processes of grinding wood and wood materials is to prepare the surface for equipment by eliminating kinematic and technological irregularities from the previous mechanical processing of wood (sawing, milling, etc.). There is a problem of processing complex profiled surfaces of products made of wood and wood materials, which today are widely used in the construction of furniture and carpentry. Domestic sanding paper does not have sufficient elasticity and allows you to process profile parts only with a radius of curvature greater than 5 mm. At smaller values of the radius of curvature, the sanding paper breaks, cracks are observed on its surface, which leads to poor processing of parts and rapid wear of the sanding belt. The authors developed the design of the elastic sanding skin and the technology of its production. Experimental studies of the developed skin were carried out, the results of the studies were presented, and the advantages of the developed elastic grinding tool were shown.
