TR28-6.3 Hydraulic Pipe Thread Molling Machine

The main characteristic of the unique 3-DIE CYLINDRICAL THREAD ROLLING MACHINE  is the central position of all 3 rolling slides in a pre-loaded double-frame. This ensures highest rigidity. By using the 3-rolls principle the needed force is brought via 3 contact zones into the workpiece material instead of 2. Thus even rolling of hollow parts is possible without compromise in quality or damaging of workpiece.


  • 3-Slide system with symmetric support of dies for centered positioning of workpiece
  • Adjustment for your quality requirement
  • close double frame that leads to minimized bending

Economical solution

  • Electronical Stroke and diameter adjustment
  • calculation of pitch deviation
  • Proposal of rolling time

1.Armpro 3-die thread rolling machine is specially designed for tubular processing. Equilateral triangle supports running to assure the roundness.
2.with 3- die thread rolling machine is with equilateral triangle supports the thread rolling for improving roundness, concentricity and vertical degree.
3.Armpro thread rolling machine is driving by hydraulic unit: Featuring in easy operation and powerful pressure.
4.Armpro thread rolling machine is set with 4 speeds transmission gear with grinding shape teeth: Featuring in noise-free, durable and precise transmission.
Particularly applied to the tubular thread processing, such as oil connectors, bicycle, automobile and motor vehicle parts, radiating pipe etc.
