Professional Round Die Thread Rolling Machine Solutions: Two-Axis vs. Three-Axis
High-Performance Two-Axis Thread Rolling Machine (Radial Type)
The Two-Axis Thread Rolling Machine, often referred to as a Radial Type thread roller, is the industry workhorse for standard fastening components. This Round Die thread making machine utilizes two parallel, co-rotating dies to extrude threads through plastic deformation. It is the ideal solution for high-volume production where cost-efficiency and speed are the primary goals.
Technical Specifications & Range
- Maximum Diameter: 80 mm (Axial feeding) / 130 mm (Radial feeding)
- Maximum Pitch: 10 mm (Axial feeding) / 16 mm (Radial feeding)
Application Scope
This Round Die threading machine is perfectly suited for standard parts, short-thread components, and workpieces with standard precision requirements. Common applications include:
- Ordinary bolts and screw rods.
- Small-diameter, short-length shaft parts.
- General hardware fasteners for construction and furniture.
Precision Three-Axis Thread Rolling Machine (Tangential/Planetary Type)
For advanced manufacturing, the Three-Axis Thread Rolling Machine offers unparalleled stability. Featuring three main spindles distributed at 120° intervals, this Round Die thread roller provides synchronous feeding. It is specifically designed to handle complex geometries and materials that require superior Concentricity of Three-Axis Thread Rolling Machine performance.
Performance Features
- Synchronous Feeding: Three-die distribution ensures balanced pressure, preventing workpiece deformation.
- Adjustable Spindle Angle: Facilitates seamless axial feeding for longer threaded sections.
- Precision Control: Equipped with roll-end adjustment and automatic thread position compensation.
- Workpiece Diameter Range: 8–90 mm.
Specialized Applications
The Rotary Thread Rolling Machine (Three-Axis) is the premier choice for:
- Hollow Thin-Walled Workpieces: Such as hollow pipe threads and lead screws.
- High-End Parts: Automotive components, hydraulic fittings, and aerospace fasteners.
Understanding the Difference in Working Principles
Choosing the right Round Die thread making machine depends on your specific production geometry and material hardness.
Two-Axis (Radial Type) vs. Three-Axis (Tangential/Planetary Type)
- Two-Axis Mechanism: The workpiece sits between two dies. The spindle drives radial feeding, and the workpiece rotates via friction. This setup is simple, fast, and economical for solid rods.
- Three-Axis Mechanism: The three dies rotate and revolve around the workpiece. Because the pressure is applied from three sides (120° apart), the Concentricity of Three-Axis Thread Rolling Machine is significantly higher. The workpiece is often fixed by a center pin, allowing for the processing of thin-walled tubes without crushing them.
