WebFeb 19, 2024 · Trepanning can also be used to produce a tube from a cylindrical billet when machining space-age metals such as beryllium. The trepanning of a cylindrical … A heated cylindrical billet workpiece is fed between two convex-tapered rollers, which are rotating in the same direction. The rollers are usually 6° askew from parallel with the billet's axis. The rollers are on opposite sides of the billet, and the surface of their largest cross sections are separated by a … See more Rotary piercing is a hot working metalworking process for forming thick-walled seamless tubing. There are two types: the Mannesmann process, invented in the 1880s, and the Stiefel process, developed two … See more The Stiefel process is very similar to the Mannesmann process, except that the convex rollers are replaced with large conical disks. This allows for larger tubes to be formed. See more
