Dimensional uniformity of the rotor used in a tachometer is claimed for a method of sintering by GKN Bound Brook. The rotor is produced for Smiths industries vehicle instrumentation division, and manufacturing costs are said to be highly favourable compared with forging the rotor or machining from bar stock.
The rotor is produced from unalloyed iron powder having the necessary magnetic properties and a minimum density of 6.5 gm/cc. After sintering the component has a tensile strength of 23,000 psi, is dimensionally stable and does not require dynamic balancing.
