Torsion Testing Machines
Overview
Metal and Wire Torsion Testing with the TNS-W100P
The 100 N·m Computerized Metal Material Torsion Testing Machine — TNS-W100P 100Nm microcomputer-controlled torsional fatigue tester — targets metal specimens, torsion bars, and engineered elastic parts where both static torsion and low-frequency fatigue must be documented on one horizontal unit.
CHENJI (Jinan Chenji International Trade Co., Ltd., testing machines since 2014) positions this 100 N.m / 100 N·m system for metal labs that need ±100 N·m capacity with 220Nm static headroom and GB/T2611-2006 compliance.
Specimens: Metal Wire, Torsion Bars, and Assemblies
The microcomputer-controlled torsional fatigue performance testing machine integrates static and dynamic functions for:
- Metal wire and bar torsion — quality sections verifying twist angle vs torque before downstream forming
- Torsion bars and shafts — angle-controlled or torque-controlled fatigue between set limits
- Spring assemblies — when horizontal layout and 200mm test space suit long or linked samples
Horizontal layout: fixed torque disk + sensor on the left; Panasonic AC servo motor with zero-backlash servo planetary reducer on the right drives the force-applying disk. Loading slides on guide rails to adjust span.

Static testing is strengthened to 220Nm overall for 200Nm maximum fatigue requirement on the strengthened machine, motor, and sensor range.
Control Modes: Torque vs Angle Fatigue
Force-controlled (torque-controlled) testing — set a torque value; fatigue runs from zero to set value or between two torque levels.
Angle-controlled testing — set angle limits; fatigue sweeps between angle setpoints.
TNS-W100P software on Windows supports real-time torque-angle curves, batch testing up to 12 test points, auto-save, A4 reports, overload/overcurrent/overvoltage/overspeed protection, and emergency stop.
Batch Workflow for Metal QC
- Clamp specimen — use jog forward/reverse on the panel for fine alignment
- Enter parameters on the graphical user interface (GUI)
- Run static torsion to peak 100Nm (or fatigue band per 0.1-3Hz rule)
- Store curves — multi-point count, save, and print per point
High-precision torque sensor (bidirectional) plus photoelectric encoder on the output shaft feed the measurement and control system.
Common Questions from Metal Testing Labs
Is this only for springs?
No — the title emphasizes metal material torsion; fixtures and span adjustment support torsion bars, wire, and assemblies within 200mm space.
How does it differ from a vertical spring tester?
Horizontal TNS-W100P suits long samples and shared static/fatigue software; torque path is optimized for 1-100Nm daily use.
Standards support?
Machine quality per GB/T2611-2006. Users may align internal procedures with ISO/ASTM methods; contact annie@chenjitester.com for English software and export documentation.
Delivery content?
Technical solution package per TNS-W100P 100Nm configuration; refer to quotation for computer/printer bundle.
