2. HR series full automatic thread rolling machine
This equipment adopts two thread profile thread rolling plate staggered 1/2 screw distance design, dead plate is fixed, movable plate equal to dead plate do straight line motion back and forth, when the work piece feed between two plates, movable plate move forward twist work piece, make its surface plastic deformation into thread.
 
Thread rolling machine is portable, flexible, high efficiency and has some irreplaceable advantages compared with similar equipment, avoid the limit of lathe, drill or hand tapping, save time, labor, not easy to rotten teeth, screw tap not easy to break off.
The machine is easy to operate, convenient to maintenance, which greatly decrease the technical requirements for workers.
