Cylindrical thread rolling dies are specialized tools used for cold forming threads on cylindrical workpieces. They are designed to produce accurate and precise threads on a variety of materials such as steel, aluminum, brass, and copper.
Thread rolling cylindrical dies are typically made of high-speed steel, or other hardened materials to withstand the stresses of the rolling process. They come in various sizes and thread profiles to accommodate different types of workpieces and thread specifications.
Thread Rolling Cylindrical Dies are made for through-feed rolling and in-feed rolling. The thread-turning device is used on a multi-axis automatic lathe to be opposite to the workpiece. The turning device is at right angles to it and moves in this direction to turn the thread. There are usually two roll cones used in one set. The 2 cones are arranged to operate in conjunction like gears. The threaded head is used to make the workpiece clamped at one end eat into the cone, and the thread is made by step rolling. After the processing is completed, the cone is opened and the workpiece can be taken out without reversing. 
The cylindrical thread rolling dies are made of high-quality tool steel Cr12MoV, which provides excellent wear resistance and durability. The dies are cylindrical in shape and are available in a wide range of sizes and thread profiles. The dimensions and shape of the dies are determined by the thread diameter and pitch of the workpiece.
We are rolling these threads:Metric thread (M),Trapezoid thread (Tr),Whitworth thread (W, BSF),Unified thread (UN, UNC, UNF, UNJF),Pipe thread (G),Round thread(Rd). Cylindrical thread rolling dies are used in various industries such as automotive, construction, and aerospace for the production of bolts, and studs as well as longer-length threaded pieces. 
In feed type thread rolling dies:(Pluge type) 
In feed type thread rolling is suitable for thread rolling shorter length. (The thread rolling length is shorter the length of the thread rolling die) 
Thru feed type thread rolling is suitable for thread rolling longer length thread rolling. Generally, there are 4 different types of thru feed:
- Annular ring type
- Helical slow feed type
- Continuous rolling type
- Speed up type
Benefit
- Cost-effective and efficient
- Consistent thread quality and accuracy
- Longer service life and reduced downtime
- Reduced tooling costs and increased productivity
- Supplying dies for ALONSO, CAMPORESI, ESCOFIER, GROB, IZPE, MAGNAGHI, MAPRE, ORT, FRITZ WERNER, SENY, TESKER, TSUGAMI, YIEH CHEN, etc. thread rolling dies.
Thread rolling with cylindrical thread rolling dies and flat thread rolling dies are two different processes for producing threads.
Flat die thread rolling uses two dies with staggered thread teeth, with the stationary die fixed in place and the moving die moving back and forth in a parallel motion to the stationary die. When the workpiece is fed between the two dies, the moving die advances to deform the workpiece surface plastically and form the thread. Flat die thread rolling is suitable for producing external threads for standard fasteners and other threaded connections in large quantities.
On the other hand, thread rolling with cylindrical thread rolling dies can be divided into three forms: axial thread rolling, tangential thread rolling, and radial thread rolling. Axial thread rolling starts from the tailstock end of the turning center and moves along the centerline of the workpiece blank, forming the thread. Tangential thread rolling forms a thread by approaching the workpiece blank from the side, and radial thread rolling forms a thread with two or three rollers during one rotation of the workpiece blank. The working range of these thread rolling methods differs, and the length of the thread cannot exceed the width of the thread rolling dies.
Each method has its advantages and is suitable for different applications. Flat die thread rolling is efficient for producing large quantities of external threads for standard fasteners and other threaded connections, while thread rolling with cylindrical thread rolling dies is a more versatile process that can produce a wider range of thread sizes and shapes.
