　　First, product introduction:

NDS series digital display type torsion testing machine is based on the GB/T2611-2007 "testing machine general technical requirements" and GB/T10128-1998 "the room temperature torsion test method" standard manufacture. Applicable standards: GB, ASTM, and other domestic and international standards. This machine has the advantages of beautiful appearance, convenient operation and stable performance.

Ji'nan radius of Testing Machines Inc production of microcomputer controlled torsion testing machine combined with foreign advanced control technology, exquisite appearance design. The Taiwan Abba high-precision ultra wide linear guide and were used ultra thick host steel structure high strength host, Taiwan TECO AC servo motor applications do to output the power passed to high-efficiency cycloidal pin wheel reduction system in order to achieve a high performance torque and torsion angle of the output and control.

NDS series digital display type torsion testing machine control system adopts the new all digital acquisition system and high precision torque sensor measurement system. Can realize the automatic calculation of the maximum torque, torsional strength and other data and indicators. The machine has no pollution, low noise, high efficiency, and has a wide range of speed regulation. This machine is suitable for all kinds of metal, nonmetal and composite materials to test the torsion performance, in line with the requirements of relevant national standards.

This machine is widely used in building materials, aerospace, machinery manufacturing, wire and cable, rubber, plastics, automobile manufacturing, shock absorber system industry material test and analysis, scientific research institutions, universities, industrial and mining enterprises, and technical supervision, commodity inspection, arbitration and other departments of the ideal test equipment.

NDS digital display torsion testing machine step by step loading method

During the test, first applying torque to the pre sample, pre torque is generally less than expected provisions of torsional stress / p0.015 10% non proportional. Install and adjust zero torque meter. Equivalent to the specified non proportional torsion should be 70% to 80% of tau p0.015 before, high grade torque is applied, applied after the small torque ratings, small torque ratings should be equivalent to less than lOMPa cut stress increment. Read all the corresponding torque and torsion angle. Read each of the time of the data is preferably not more than 10s. The elastic part of the torsional torque calculated from all levels minus the twist angle of the reading angle, the non proportional part of the torsional angle. Applying torque until a non proportional torsion angle is equal to or slightly greater than the value specified.

NDS digital display torsion testing machine working environment

1, at room temperature 10 C ~ 35 C range, the relative humidity is less than 80%;

In 2, a solid foundation or table;

In 3, no vibration and no corrosive medium surrounding environment;

4, in the experimental process, the test pieces bear the torque force measurement pointer has been turned, it is not able to change the range selector knob.

5, emergency stop switch is abnormal when the machine is used in emergency situations, can not be used as a stop button

6, the use of V shaped clamp specimens, the specimen must be clamped to avoid slipping during the test.

7, when the test, if found abnormal phenomenon, should immediately stop, investigate and deal with the cause of failure, to be repaired before re start.

8, the hand wheel switch in the NDS digital display type torsion test machine calibration machine or the case of the use of the disc

9, screw loading speed adjustment knob to slow, that is, the first low speed to load, to achieve a certain deformation, and then transferred to the speed required to load.
