1. A method of machining rotary-shaped objects from tool sinters and quenched steel, characterised in that a machined rotary object (14) is mounted in a grip (9) of a horizontal spindle (8) and the object (17) is rotated, and at the same time the object (14) is additionally given, relative to the wire electrode (2), two mutually correlated perpendicular linear movements along the x and y axes in the plane of the table (11).2. A device for using the method according to Claim 1, composed of an electroerosive wire cutting-off machine, e.g. of the SCX or SCX-2 type, arm clamps and a device for all-purpose tool grinding of Jungner type, which device has, in its body, a spindle mounted horizontally on bearings with a self-centring chuck and its own spindle drive from an electric motor via a belt transmission, characterised in that the body of the device (5) is fitted, at the bottom, with an insulating board (12), and at the top, at the points where it is mounted by the arms of the arm clamps (10), with an insulating strip (13), and on the lateral surface with the electric terminal (15) of the positive pole of the working voltage supply (16).<IMAGE>
