Nuclear Non-proliferation Import and Export Control Regulations — B.2.1
B.2.1 Industrial equipment B.2.1.1 Flow-forming machines and spin-forming machines capable of flow-forming functions, and mandrels, as follows, and specially designed software for them: (a) machines having three or more rollers (active or guiding) and that, according to the manufacturer’s technical specification, can be equipped with numerical control units or a computer control; and (b) rotor-forming mandrels designed to form cylindrical rotors of inside diameter between 75 mm and 650 mm. NOTE Paragraph (a) includes machines that have only a single roller designed to deform metal and two auxiliary rollers that support the mandrel but do not participate directly in the deformation process. B.2.1.2 Machine tools and specially designed software as follows: (a) machine tools, as set out below, and any combination of them, for removing or cutting metals, ceramics or composites, which, according to the manufacturer’s technical specifications, can be equipped with electronic devices for simultaneous contouring control in two or more axes: (1) machine tools for turning, that have positioning accuracies with all compensations available better (less) than 0.006 mm according to ISO 230/2 (1988) along any linear axis (overall positioning) for machines capable of machining diameters greater than 35 mm; NOTE Paragraph B.2.1.2.(a)(1) does not include bar machines (Swissturn) limited to machining only bar feed thru, if the maximum bar diameter is equal to or less than 42 mm and there is no capability of mounting chucks. Machines may have drilling and/or milling capabilities for machining parts with diameters less than 42 mm. (2) machine tools for milling having any of the following characteristics: (i) positioning accuracies with all compensations available are better (less) than 0.006 mm according to ISO 230/2 (1988) along any linear axis (overall positioning); (ii) two or more contouring rotary axes; or (iii) five or more axes that can be coordinated simultaneously for contouring control; NOTE Paragraph B.2.1.2.(a)(2) does not include milling machines having the following characteristics: (a) x-axis travel greater than 2 m; and (b) overall positioning accuracy on the x-axis worse (more) than 0.030 mm according to ISO 230/2 (1988). (3) machine tools for grinding having any of the following characteristics: (i) positioning accuracies with all compensations available are better (less) than 0.004 mm according to ISO 230/2 (1988) along any linear axis (overall positioning); (ii) two or more contouring rotary axes; or (iii) five or more axes that can be coordinated simultaneously for contouring control; and NOTE Paragraph B.2.1.2.(a)(3) does not include the following grinding machines: (a) cylindrical external, internal and external-internal grinding machines having all of the following characteristics: (i) limited to a maximum workpiece capacity of 150 mm outside diameter or length; and (ii) axes limited to x, z and c; and (b) jig grinders that do not have a z-axis or a w-axis with an overall positioning accuracy less (better) than 0.004 mm (positioning accuracy is according to ISO 230/2 (1988)). (4) non-wire type electrical discharge machines that have two or more contouring rotary axes and that can be coordinated simultaneously for contouring control; and NOTE Paragraph B.2.1.2.(a) does not include special purpose machine tools limited to the manufacture of any of the following parts: (a) gears; (b) crankshafts or camshafts; (c) tools or cutters; and (d) extruder worms. (b) software: (1) software specially designed or modified for the development, production or use of equipment referred to in paragraph B.2.1.2.(a); and (2) software for any combination of electronic devices or systems enabling those devices to function as a numerical control unit capable of controlling five or more interpolating axes that can be coordinated simultaneously for contouring control.
