Thread Rolling Dies

Thread rolling dies is a tool for rolling threads by means of metal plastic deformation on the wire rolling machine. The high-quality wire rolling die is required to be made of Cr12MoV material, with hardness above HRC62, wear resistance, and long service life.

Thread rolling tools including flat dies, planetary dies, thread rolling cylindrical dies and annular thrufeed threading dies adopt advanced alloy tool steel and professional vacuum heat treatment, so uniform hardness, extremely high stability, professional and rigorous manufacturing, and quality control, regardless of teeth, and the teeth are extremely high.

We offer good customization services, special specifications, such as screw thread, screw pitch, thread number, etc., can be customized according to customer’s needs.

Annular thrufeed threading dies

Annular Thru-feed Threading Dies are used for rolling threads that exceed the max die width with the thread form ground on the die in straight rings, not helix.

  • Made of selected tool steel Cr12MoV, high hardness and wear-resistance for a long lifespan.
  • Uniform accurate threads for meeting precision threading demands.
  • Smooth surface to produce a better thread.
  • Easy installation and reduced setup time for higher production rates.
  • Supplying dies for ALONSO, CAMPORESI, ESCOFIER, GROB, IZPE, MAGNAGHI, MAPRE, ORT, FRITZ WERNER, SENY, TESKER, TSUGAMI, YIEH CHEN, etc. thread rolling dies.
  • Regrinding service is available.

Problems Reasons Solutions
Slivers or flakes Dies not in match Resynchronize rolls
Center line of rolls not parallel with center line of work Check slide for alignment
Deep cross-nicking on dies Check slide gib and springs. Tighten adapter if used.
Feed rate too slow, causing rolls to slip on work Increase rate of penetration
Rough finish on blank Regrind tooling
Machine and dies too large and clumsy for the job Use correct rolls for job
Overfilling dies Reduce blank diameter
Material not adaptable to cold-working Change material. Check with material supplier.
Seamy stock Not suitable for roll threading
Poor finish on thread Corresponding poor finish on the dies Replace rolls
Dies that are worn out or broken Replace rolls
Dies not in match Resynchronize rolls
Chips, from other operations, between rolls and work. Make sure a good jet of clean oil is reaching rolling position.
Material accumulated in threads on roll Replace rolls if material cannot be removed.
Material not ductile enough for coldworking Change material
Split thread Seamy stock Change stock
Dies too short for the job Replace rolls
Drunken Threads Rolls not in match Resynchronize rolls
Center line of rolls not parallel with center line of work Check slide for alignment
Inaccurate rolls Replace rolls
Work bending during rolling. Support part during rolling operation or slow down penetration rate if possible
