Abstract
In the manufacture of internal thread by taps, the quality may be improved by special preparation of the three tap sections with different functions. The sections are subjected to differential magnetic–abrasive finishing on a CNC system, taking account of their specific characteristics and functions (roughing, semifinishing, and finishing, respectively). The use of such taps decreases the surface roughness Ra of internal threads in 12Cr18N10T stainless steel by a factor of 1.3–3.
