One very interesting later development for Moore was their involvement - in conjunction with Dallas Optical Systems - in building ultra-precision diamond-turning machines with spindles turning in hydrostatic and, later, air-bearings. These machines CNC-controlled could produce precise contours on X-ray and other types of very large telescope mirrors and also, in the form of a horizontal and vertical lathes, shafts turned parallel and tapered to the very highest standard of accuracy. Designed by the CEO of Dallas Optical Systems, John Casstevens, the Moore Nanotechnology Systems Company build a dedicated facility to produce these and similar machines.
