Mass production of standard fasteners
Manufacturing of key automotive parts
Heavy machinery thread forming
PRODUCT DETAILS |
Our thread rolling machines revolutionize metal component production by utilizing advanced cold-forming technology to create superior, high-strength threads with unmatched precision. Designed for efficiency and durability, our machines transform raw materials into perfectly threaded parts through a pressure-based rolling process that enhances material properties while maintaining tight tolerances.
From mass-producing standard fasteners to crafting specialized threads for critical applications, our versatile solutions serve industries ranging from construction and automotive to aerospace and heavy machinery. The cold-rolling process not only improves thread strength by up to 30% but also delivers exceptional surface finishes and dimensional accuracy, all while reducing material waste and energy consumption.

FAQ |
1. How does a thread rolling machine work?
A thread rolling machine uses cold-forming technology to press rotating dies against a metal workpiece, displacing material to form threads without cutting. This enhances strength by preserving the metal grain structure.
2. What materials can be processed?
Suitable for carbon steel, alloy steel, stainless steel, copper, aluminum, etc. (Max hardness HRC≤38). Harder materials require annealing first.
3. Advantages over thread cutting?
30% higher tensile strength (work hardening effect)
Superior surface finish (Ra≤1.6μm)
Faster production (up to 120 pcs/min)
No metal chips, eco-friendly
4. Maximum thread diameter capacity?
Standard models cover M3-M100; custom machines available for larger sizes (e.g., oil drill pipes).
5. How to ensure thread accuracy?
Precision dies (HRC60-62 hardness)
Stable hydraulic pressure (±2% fluctuation)
CNC models achieve ±0.02mm tolerance
6. Is lubrication required? What type?
Essential! Use extreme-pressure (EP) metalworking oil (sulfur/chlorine additives) to reduce die wear and improve finish.
7. Key maintenance practices?
Daily: Check hydraulic oil level/filters
Every 500hrs: Replace lubricant
Regularly: Align dies, clean guide rails
