EZ-20 Computer Control Torsion Testing Machine Of Bone Screw
 
EZ-20 Computer control torsion testing machine is mainly used in the torsion test of metal and nonmetal materials, mechanical parts.Widely used in the mechanics laboratory of Colleges , universities , scientific research units and the quality inspection department of the enterprise.


The test machine adopts computer control software operation, It can display all kind of curve in the same time, such as torque - time ,torsion angle-time, torque -torsion angle; Real time display angle, torque, Peak value and other parameters; the test results can be stored and printed.
Standard 

This type machine can be used to test the torsional strength and torsional angle of various materials with related fixtures. Meet the requirements of torsion angle and torque test in the standard ASTM F 543 and YY 0018-2008 Bone joining implant metal bone screw

Host structure and working principle

This type machine include Host,control and measurement system. The measurement and control part is composed of a computer unit, a digital measurement controller (torque detection unit and a torsion angle detection unit).The main features of the machine:
1.The test machine adopts computer control software operation to realize the measurement of torque and torsional angle .Control the operation,stop,forward and reverse of the work piece .
2.When the machine is working, the instructions are given by the computer,The speed and steering of the servo motor is controlled by the servo control system .Applying torque to the sample through the rotation of the chuck.
The torque is detected by the torque sensor, and the torsional deformation is measured by the digital measuring controller, and then amplified and processed, and finally sent to the computer to display the curve of the torque-angle.
3.closed-loop control, three control modes (torque control ,torsion angle control and chuck angle control) can be switched automatically
4.Test speed is adjustable according to the test requirement .

Main Section :
1.Host Frame:Horizontal structure;Welding base;High precision guide rail+slider,Good rigidity, high precision..
2.Transmission System:Use Panasonic AC servo system ,Frequency converter and Deceleration system
3.Force Measuring System:Include High precision torque sensor and AD chip
