Description
Bysen hydraulic circular thread rolling machine is a high-performance industrial machine designed for precision thread forming on cylindrical workpieces. Utilizing advanced hydraulic pressure and precision-ground dies, it delivers superior thread quality, efficiency, and durability compared to traditional thread-cutting methods.
1. Robust & Stable Design
Heavy-duty construction with reinforced frame and high-strength materials to withstand high rolling forces.
Vibration-damping mechanisms ensure smooth operation even at high speeds.
Rigid spindle & guide systems prevent deflection, maintaining accuracy under load.
2. Powerful Hydraulic Drive System
High-torque hydraulic motor provides consistent rolling force for tough materials (e.g., stainless steel, alloy steel, titanium).
Adjustable hydraulic pressure allows optimization for different material hardness and thread profiles.
Energy-efficient operation reduces power consumption compared to mechanical alternatives.
3. Superior Thread Quality & Precision
Rolls threads with tight tolerances (up to ISO 6g/6h or ANSI Class 2A/2B standards).
Cold-forming process enhances thread strength by improving grain structure (no material removal).
Smooth surface finish (Ra < 1.6 μm) reduces friction and improves fatigue resistance.
4. Low Noise & High Reliability
Precision gearbox & bearing systems minimize operational noise (<75 dB).
Sealed hydraulic components reduce contamination risks and maintenance needs.
Long-lasting dies (hardened tool steel or carbide) ensure extended service life.
5. Easy Setup & Adjustability
Quick-change die system for fast transitions between thread types (metric, trapezoidal, ACME, etc.).
Digital or manual depth adjustment for fine-tuning thread dimensions.
User-friendly control panel (PLC or CNC options available for automation).
Wide Range of Applications
This machine is ideal for producing external threads on:
✔ Fasteners – Bolts, screws, studs, threaded rods
✔ Construction hardware – Sleeve anchors, rebar connectors, foundation bolts
✔ Automotive & aerospace parts – Axles, shafts, hydraulic fittings
✔ Mechanical components – Lead screws, worm shafts, modular gears
Thread Types & Capabilities
Standard threads: Metric (M), UNC, UNF, Whitworth, BSW
Special threads: Trapezoidal (Tr), ACME, stub ACME, modular (DP)
Custom profiles: Can be tailored for unique industrial requirements
Additional Forming Functions
Beyond thread rolling, this machine can perform:
Knurling (straight, diamond, or cross patterns)
Grooving & undercutting
Shoulder forming & chamfering
Advantages Over Thread Cutting
3-5x faster production (single-pass rolling vs. multiple cutting passes)
No chip generation (eco-friendly, no material waste)
Increased thread strength (up to 30% higher fatigue resistance)
Lower tooling costs (dies last longer than cutting tools)
Ideal for Industries:
Fastener manufacturing
Oil & gas pipeline fittings
Heavy machinery & equipment
Precision engineering & defense
