units or a computer control;
b. Rotor-forming mandrels designed to form cylindrical rotors of inside diameter between 75 mm and 650 mm.
Note: 2B209.a. includes machines which have only a single roller designed to deform metal plus two auxiliary rollers which support the mandrel, but do not participate directly in the deformation process.
2. B. 219. Centrifugal multiplane balancing machines, fixed or portable, horizontal or vertical, as follows:
a. Centrifugal balancing machines designed for balancing flexible rotors having a length of 600 mm or more and having all of the following characteristics:
1. Swing or journal diameter greater than 75 mm;
2. Mass capability of from 0.9 to 23 kg; and
3. Capable of balancing speed of revolution greater than 5,000 r.p.m.;
b. Centrifugal balancing machines designed for balancing hollow cylindrical rotor components and having all of the following characteristics:
1. Journal diameter greater than 75 mm;
2. Mass capability of from 0.9 to 23 kg;
3. A minimum achievable residual specific unbalance equal to or less than 10 g mm/kg per plane; and
4. Belt drive type.
2. B. 225. Remote manipulators that can be used to provide remote actions in radiochemical separation operations or hot cells, having either of the following characteristics:
a. A capability of penetrating 0.6 m or more of hot cell wall (through‑the‑wall operation); or
b. A capability of bridging over the top of a hot cell wall with a thickness of 0.6 m or more (over‑the‑wall operation).
Technical Note:
Remote manipulators provide translation of human operator actions to a remote operating arm and terminal fixture. They may be of 'master/slave' type or operated by joystick or keypad.
2. B. 226. Controlled atmosphere (vacuum or inert gas) induction furnaces, and power supplies therefor, as follows:
N.B.: SEE ALSO 3B.
a. Furnaces having all of the following characteristics:
1. Capable of operation above 1,123 K (850°C);
2. Induction coils 600 mm or less in diameter; and
3. Designed for power inputs of 5 kW or more;
2. B. 226. b. Power supplies, with a specified power output of 5 kW or more, specially designed for furnaces specified by 2B226.a.
Note: 2B226.a. does not apply to furnaces designed for the processing of semiconductor wafers.
2. B. 227. Vacuum or other controlled atmosphere metallurgical melting and casting furnaces and related equipment as follows:
a. Arc remelt furnaces, arc melt furnaces and arc melt and casting furnaces, having both of the following characteristics:
1. Consumable electrode capacities between 1,000 cm3 and 20,000 cm3; and
2. Capable of operating with melting temperatures above 1,973 K (1,700°C);
