Abstract (English):
The well-known discrete abrasive discs are characterized by a high vibration level of the technological system that causes the geometrical characteristics degradation of surfaces ground, life and technological equipment decrease and tool quick wear. New methods of the high-frequency discretization of a cutting surface with the use of a laser beam and a hydro-abrasive jet and also designs of grinding tools decreasing a vibration level of the technological system are developed. The processes of the high-frequency discretization of grinding discs are improved experimentally: the path of a high-concentrated energy flow motion is substantiated, the modes of hole cutting out in abrasive of a tool and a field of the application of a laser beam and a high-pressure hydro-abrasive jet are defined.
