PR-60A / THREE DIES ROLLING

Thread Rolling Machine

This machine is designed for the thread/profile forming on the thin pipes/tubes, which equipped with 3 same size rolling shafts and needs 3 pieces of rolling dies while rolling. These three shafts are swivel able to ensures optimum capacity and use in making threads and axially parallel profiles in the through-feed process. For this special through-feed process automatic feed of the work is necessary.
This machine can also be used in the in-feed process with parallel die axes, the length of the profile to be rolled depends on the width of the rolling dies, there is no axial movement of the workpiece.
Tapered pipe thread (PT, FT series) forming are most common applications by this machine.
