Description
High-Precision Thread Rolling Equipment

The Two-Roller Thread Rolling Machine is a high-efficiency metal forming machine designed for external thread rolling, bolt thread forming, screw thread processing, stud manufacturing, shaft threading, and precision fastener production. Using two rolling dies to press and form threads on the workpiece surface, this machine provides stable thread accuracy, smooth surface quality, high production efficiency, and reliable forming performance.

Unlike traditional thread cutting, thread rolling is a chipless cold forming process. The material is plastically deformed by the rolling dies to create strong and uniform thread profiles. This helps improve thread strength, surface hardness, fatigue resistance, and material utilization while reducing cutting waste.

The two-roller structure supports stable clamping and forming force during operation, making it suitable for processing bolts, screws, studs, threaded rods, shafts, pins, pipe fittings, and other cylindrical metal parts. Depending on roller die design and machine configuration, it can also support straight threads, fine threads, knurling, and special thread profiles.

The machine is suitable for carbon steel, alloy steel, stainless steel, copper, aluminum, and other ductile metal materials according to workpiece hardness, roller die specification, lubrication, and forming parameters. It is widely used in fastener factories, hardware production, automotive parts manufacturing, machinery components, construction parts, and industrial metalworking.

For manufacturers looking for efficient and reliable thread forming equipment, the Two-Roller Thread Rolling Machine provides high productivity, stable thread quality, strong forming capability, flexible application, and long-term industrial value.

Two-slide CNC Thread Rolling Machine Design Principle
To process higher-quality workpieces, its feed method is upgraded from single-slide to two-slide, placing the workpiece between two rollers. During operation, left and right slide rollers move toward and roll the workpiece simultaneously, ensuring uniform rolling pressure on both sides and avoiding precision loss from workpiece deflection in one-way feed. It also enables better clamping/positioning for axial feed, facilitating automated loading/unloading to enhance workpiece stability and precision. This CNC thread rolling machine is a leader in thread rolling machine industry of China.

Machine Features:

  1. Specifically designed for high-precision workpieces, especially shaft parts processing, such as ball screws, worm gears, and gear rolling densification.
  2. The feed and transmission power sources are driven by servo motors, facilitating adjustment and data collection.
  3. The feed part uses a servo motor to drive the RV reducer and planetary roller screw, increasing the machine's torque and durability. Typically, other machines use ball screws, but our planetary roller screw output is 5-10 times that of ball screws.And the accuracy of the workpiece is ensured through the detection of the grating ruler.
  4. Transmission part:
    A) The S30CNC uses a servo motor directly connected to a high-quality planetary reducer to drive the roller shaft, ensuring the roller shaft's operating precision and operability.
    B) The S50CNC & S70CNC have increased transmission torque compared to the S30CNC, Two servo motors are used to brake the two roller shafts in the gearbox, which are connected by a cage drive shaft. This improves the traditional transmission shaft's uneven speed characteristics and ensures smoother operation.
  5. The human-machine interface makes operation easier and more user-friendly.
  6. Since the workpiece is located on the middle feeding component, connecting to automation is more convenient, fast, and simple.
