Invented more than 70 years ago to de-glaze cylinder bores in early automobile engines, conventional honing today is meeting the most advanced aerospace requirements for ultra-precise machined parts. Computer controls, new tool designs, new abrasives, integrated air-gage part measurement, and servo-driven tool feed systems and spindles enable new honing machines to produce part bores with 0.000010-inch accuracy and crosshatched surface finishes targeted to a very narrow range. Honing can even correct bore geometry distortion from upstream machining processes, welding, or heat treating. And while most users want a uniform round shape in a bore, honing can also impart a shape, such as a barrel, in a selected region of a bore if desired.
