Spring torsion fatigue testing machine
Standard
- JB/T 9370 (Chinese national standard for torsion testing machines)
- JJG 269 (Chinese verification regulation for torsion testers)
- ISO 12106 (International standard for metallic materials—torsional fatigue testing)
- ASTM E143 (Standard test method for torsional fatigue of metallic materials)
Product Advantages
- Automated Precision
- Digital control: Real-time display of torque, angle, and cycle count.
- Absolute rotary encoder: Eliminates cumulative error for ±0.1° accuracy.
- User-Defined Flexibility
- Adjustable parameters: Torsion angle (0–300°), frequency (0–5Hz), and direction (clockwise/counterclockwise).
- Preset cycles: Auto-stop at 999,999,999 cycles with buzzer alert.
- Quiet Operation
- 50dB noise level: Suitable for lab environments.
- Vibration damping: Reduces mechanical resonance during high-cycle testing.
- Data Integrity
- Automatic storage: Resumes tests after power interruptions.
- Multi-unit display: Torque (Nm/lb-ft) and frequency (Hz/RPM) shown simultaneously.
- Industrial Durability
- Alloy steel frame: Rigid construction with 10-year lifespan.
- Sealed bearings: Maintenance-free operation for 20,000+ hours.
Product Features
Testing System
- Torque Application:
- 300° adjustable angle: ±0.1° resolution via servo motor.
- 10/20/50Nm ranges: Auto-switching for lightweight to heavy-duty springs.
- Control Panel:
