Abstract: A magnetic-abrasive powder has a magnetic component, an abrasive component, an adhesive component which connects particles of the magnetic component with particles of the abrasive component, the adhesive component being a light curing adhesive component which contains catalysts and is polymerizable under the action of ultraviolet and visible light.

Abstract: A method of machining flat parts, includes the use of two permanent magnets which are located opposite to and spaced from one another so as to form a magnetic field with a magnetic flux extending perpendicular to the magnets, placing a flat part in the magnetic field between the magnets so that the magnetic flux extends through the flat part, supplying a magnetic-abrasive powder to the flat part in the magnetic field, and performing a relative movement between at least one of the magnets and the flat part so as to remove a material from a surface of the flat part.

Abstract: Magnetic-abrasive machining of a parts is performed by generating a magnetic field by two different poles located near one another so as to form a magnetic gradient region with magnetic flux lines which extend from one pole in one direction and then in an opposite direction to another pole and therefore are round in a predetermined plane, placing a part to be machined exclusively at one side of the two poles, introducing a magnetic-abrasive powder between the poles and the part to be machined so that a portion of the part to be machined is located in the magnetic gradient region with the round magnetic flux lines, and moving the part to be machined relative to the poles in the same plane transversely to the round magnetic flux lines of the magnetic gradient region so that portions of the part to be machined successively pass the magnetic gradient region with the round magnetic flux lines and are machined by the magnetic-abrasive powder retained in the magnetic gradient region with the round magnetic flux line

Abstract: A magnetic-abrasive powder includes a magnetic component of a powder of a magnetic material, an abrasive component of a powder of an abrasive material, and an adhesive which adhesively connects particles of the magnetic material with particles of the abrasive material.
