Threading rolling machine R3-20Z

Key Advantages of the Yuhai R3-20Z Thread Rolling Machine

• Small Workpiece Capability — Designed for rolling threads on miniature workpieces with a diameter of 3 mm and a length of up to 20 mm, making the machine an ideal solution for producing small fasteners such as micro screws, electronic fastenings, and precision fasteners for watchmaking and medical applications.

• High Processing Accuracy — Ensures consistent thread profile quality thanks to precision die adjustment and minimal backlash in the working units, which is critical when manufacturing small-diameter components.

• Cold Forming Technology — Forms threads through plastic deformation without chip removal, which is especially important for miniature parts: it eliminates the risk of workpiece damage, enhances thread strength, and preserves the corrosion-resistant properties of surface coatings.

• Ease of Operation — An intuitive control panel with minimal setup requirements allows operators to quickly master machine operation and perform changeovers to a new size type in just a few minutes.

• Application Versatility — Suitable for rolling metric (M2–M6), inch, and specialized fine threads on workpieces made from soft and medium-carbon steels, brass, aluminum, and copper alloys.
