You know you’re in for a treat when you are told that a lathe which can reach a resolution of one micrometer (1×10 −6, a millionth of a meter, or 0.00004″ for people who love zeros) is ‘not hard to ...

Bearings define speed, load-carrying capacity, precision, and stiffness, and they contribute to the spindle operating temperature, vibration, and noise during operation. It wasn’t so long ago that a ...

The challenge that machine tool builders face when designing spindles for milling machines and lathes is selecting bearings with the optimal balance of speed, load-carrying capacity, stiffness, and ...

Modern CNC machine tools work under increasingly diverse cutting conditions. They must handle workpieces of various sizes and materials, and produce good surface finishes while operating at ever ...

Instrument bearings can be lubricated with oil, grease, or dry films. Oils: Synthetics are used most widely for instrument bearings. Petroleums also are used for their excellent lubrication properties ...
