Heat treatment of dies is carried out in vacuum furnaces. Saw blade segment, segments, the Planetary rolling the most productive method of rolling threads, as it allows to produce a continuous and simultaneous machining of several workpieces. For this method is characterized by a complete automation, the high resistance retinoblastoma tool, high precision and stability. Planetary rolling of external threads is carried out according to several schemes: the video segment; clip ring; two pairs of rollers-segments in the inclined arrangement of the work spindle; two pairs of rollers of the segments in the horizontal layout of the work spindle; two pairs of rollers segments consistently on the duplex machine. Basic is a scheme in which the the billet is rolled in the direction of arrow S between the concave part threaded segment and a continuously rotating threaded roller (Fig. 1). Of the blank from the hopper, serves to periodically boot device so that in the area of rolling all the time is one or more blanks, simultaneously passing all the stages of formation of the thread.

Rollers segments designed for rolling external thread on the planetary method special machines models А2518, АА2518, А2520, АА2520, А2521, А2522 and other.
