Product Overview

Our two-axis thread rolling machine is a professional heavy-duty cold forming equipment dedicated to high-precision and high-strength thread processing. Adopting advanced two-die synchronous extrusion technology, it forms threads through cold plastic deformation of metal without cutting chips. Compared with traditional thread cutting process, it greatly improves the surface finish, dimensional accuracy, tensile strength and fatigue resistance of finished threads, and is widely used in manufacturing high-grade fasteners and structural parts.

Core Advantages

1. High Precision & Consistent Forming Quality The two-die synchronous rolling structure ensures uniform and stable extrusion force, producing full, smooth and standard thread profile with high pitch accuracy. Batch processed workpieces have excellent consistency, which fully meets the quality requirements of high-strength standard parts and precision mechanical components.
2. Heavy-Duty Rigid Structure, Long Service Life The whole machine adopts integral cast iron fuselage with excellent rigidity and shock absorption performance. It maintains stable operation with low vibration and low noise even under long-time heavy load working conditions, effectively reducing equipment wear and prolonging the service life of both the machine body and thread dies.
