GenTor – Horizontal Torsion Tester

Torque repeatability is within ±1.0%, specified from 20% of each full range. Repeated tests on like specimens should give torque values that agree within that band, as long as the torque you measure sits in the upper 80% of the frame's range.

That 20% starting point is the figure to check when choosing a capacity. All five frames, from 200 N·m to 6,000 N·m, are held to the same repeatability, but each only above a fifth of its own range, so a 6,000 N·m machine is the wrong choice for a 30 N·m fastener even though it can apply that torque.

Keeping the figure over the life of the machine is a matter of calibration. Our operation manual calls for torque calibration once a year, a calibration lever ships with the machine, and we provide calibration as part of the support we give for the life of the equipment.

NextGen GenTor Torsion Tester is designed to deliver precise and reliable measurements of torque and torsion angle through its advanced features and high-precision sensors. Equipped with a top-of-the-line torque sensor, this testing machine ensures accurate measurement of the torque value exerted on the material under examination. The torque sensor is specifically engineered to provide precise readings, enabling accurate torsional assessment.

Moreover, NextGen’s GenTor Torsion Tester incorporates a high-precision torsion angle meter that accurately measures the torsion angle of the material. This meter is finely calibrated to capture even the slightest angular changes, offering a detailed understanding of the material's behaviour under torsional stress.

These high-precision sensors synergize with the tester's advanced control system and data processing capabilities. The real-time display of testing data and various testing curves empowers users to closely monitor torque and torsion angle values throughout the testing process, ensuring meticulous measurement accuracy.

The space between the grips depends on the capacity. The 200 N·m and 500 N·m frames take specimens from 0 to 500 mm (19.7 in) between grips, and the 1,000 N·m and 2,000 N·m frames from 4 to 1,000 mm (39.4 in). For the 6,000 N·m frame, the grip distance is confirmed at quotation.

Because the frame lies horizontally, a long specimen sits between the grips without extra support, so length is limited by grip distance rather than by headroom.

Measure the longest specimen you plan to test, including the length each grip needs to hold it, before settling on a capacity. Tell us your specimen length and target torque and we will confirm the capacity and grips that fit.

The maximum test speed is 1.5 RPM, the same on all five capacities of the NDW-6000 platform. It is the ceiling of the drive rather than the rate every test runs at: the rate for a given method is entered in the software before the run, and a slower rate is set whenever your procedure calls for one.

The drive is a servo motor that turns the moving grip through a reducer. The control unit receives the test instruction from the computer and drives the motor in closed loop against the speed you set.

During a run the operator can halt the drive at any moment with the red emergency stop button on the machine. Our operation manual lists the working conditions: a level, solid base free of vibration, a room between 10°C and 40°C, and a supply that stays within ±10% of the rated voltage.

The GenTor runs from English testing software on a PC, and the software controls the test in closed loop. The machine holds the value you set, rather than following a fixed motor speed.

A test can be driven at constant rotation angle or at constant torque. Once the target is reached, the software holds it for a duration you set, which suits procedures that call for a hold at a set torque or angle.

Test speed and the other control parameters are entered on the parameter screen before the run starts. For a laboratory that has to repeat a method, that matters more than the peak number: the same target and the same hold time give the same test next week, on the next batch or with a different operator.

Torsion speed is adjustable from 0.1 to 1000°/min, steplessly, so any rate inside that span can be entered rather than picked from fixed steps.

The speed is one of the control parameters set in the software before the run, and the actual torsion speed is shown live on screen next to torque and angle, so you can see that the programmed rate is being held.

Torsion results can depend on the twist rate, which is why the wire torsion methods we reference control twisting speed, and why a test series should keep one rate from the first specimen to the last. Our article on torsion analysis with the GenTor walks through how a test is set up.

The angle reading goes up to 9999.9°, which is just under 28 full turns of the moving grip. The count carries on through each revolution, so a specimen that twists many times before it fails is followed to the end of the test.

Angle comes from an optical encoder, while torque comes from a separate sensor behind the fixed grip. The two are measured independently, so neither value is calculated from the other.

For a wire or bar test that reports turns to failure, check the expected number of turns against this limit when you plan the method. To compare the GenTor with our other machines for a given turn count, torque and specimen length, see our torsion testing machines.

ISO 7800 is the simple torsion test for metallic wire. A straight wire is twisted about its own axis in one direction, and its torsional ductility is expressed as the number of turns it withstands, either to fracture or to a specified count. The method covers round and shaped wire from 0.1 mm to 14 mm.

Wire producers and buyers use it as a production or incoming-inspection check, and it is often written into wire product standards and purchase documents when the wire will later be formed, coiled or twisted.

On the GenTor, one grip turns while the other stays fixed over the torque sensor, so the specimen is twisted about its own axis, which is the loading ISO 7800 applies, and the angle count follows every turn.

Grip alignment, speed and specimen handling all affect a wire result, so we match grips and capacity to your wire size, turn count and cited edition. Send us your wire specification to confirm the setup.

ASTM A938 is the ASTM test method for torsion, or twist, testing of metallic wire. It checks how much ductility a wire shows in twist, and it is written for the wire product form, not for strip, rod or larger torsion bars.

The method controls specimen straightening and end preparation, the test length between the clamping heads, clamp alignment, the tensile force that keeps the wire straight while it twists, and the twisting speed and turn count.

The acceptance limit comes from the product specification or the customer requirement, not from A938 itself, so a drawing that calls for a minimum twist result is read together with the method.

Before we quote a GenTor for A938 work, we check your wire diameter, test length and turn count against the grips and grip distance of the frame, and settle how the wire is held straight during twisting.

ASTM E143 is a standard test method established by ASTM International for measuring the modulus of elasticity in torsion. This standard provides guidelines for determining materials' torsional properties, specifically the shear modulus or rigidity modulus.

The standard outlines the procedure for performing torsion tests on cylindrical specimens to measure their shear modulus. The shear modulus is a measure of a material's resistance to shear deformation under torsional forces.

The ASTM E143 test method involves applying torque to a specimen while measuring the resulting angular displacement. The shear modulus is then calculated based on the specimen dimensions and the applied torque.

The standard provides specifications for test setup, specimen preparation, test procedure, and data analysis. It ensures that the torsion test is conducted accurately and consistently across different laboratories and testing facilities.

NextGen GenTor Horizontal Torsion Tester complies with ASTM E143 standard.

Yes. Test data appears on the PC screen in real time while the specimen twists, and the test curve is drawn as the run goes, so the operator watches the response develop instead of waiting for a single number at the end.

The live readout covers torque, yield torque, maximum torque, torque strength and torsion angle. A separate parameter screen is used to set up the test before the run starts.

Behind the display, the torque sensor signal passes through the amplifying circuit in the control unit and is converted from analogue to digital, while the angle is read at the same time. Both values on screen therefore come from the same moment of the test.
