ASTM E328 AS 4672 ASTM A416 Tensile Strength Instrument 300KN Electromechanical Tensile Stress Relaxation


Wire tensile testing machine 300kN stranded wire stress relaxation ASTM E328 MSR305


MSR305 microcomputer control tensile stress relaxation testing machine possesses the characteristics of compact structure, simple and easy to use and can be applied to the biggest load of 300 kn metal materials (such as steel wire, PC steel bar and steel wire) mechanical properties of the tensile stress relaxation test at room temperature.

The main engine consists of frame, trough frame, and anti-force frame, which are equipped with precision ball screw, speed reducer, and left and right drawing anchor etc.Transmission loading system adopts well-known servo drive control the servo motor, reducer and circular arc tooth synchronous belt, driving high precision ball screw nut rotation, drive screw about sports, for sample loading, thus complete relaxation test of metal specimens.This machine has a novel appearance, reasonable structure, large rigidity, good stability, accurate transmission, excellent control, low noise, easy to use, etc.


Standards: ASTM E328 Standard Test Methods for Stress Relaxation Tests for Materials and Structures.


Frame

  • Robust guidance columns with self-lubrication increase lateral stiffness and ensure linear crosshead travel. This results in accurate crosshead alignment thus reducing variability in measurement data and producing better overall accuracy
  • Pre-loaded ball screws and heavy duty bearings assure long life with zero backlash as well as linear low force and through zero performance. The result is accurate and repeatable measurements that truly represent the specimen characteristics rather than load frame deficiencies
  • Fully-protected lead screw covers provide longer life and greater operator protection
  • Easy-to-clean aluminum column covers with chamfered corners to facilitate access to the test area. T-slots are built in for simple, convenient attachment and positioning of testing accessories

Driving system


  • Japanese PANASONIC AC servo motor and arc-shape silent synchronous belt features high-speed, low vibration, world-class, and maintenance-free
  • Germany NORD gear reducer offers low noise, low heating, and high efficiency
  • Photoelectrical encoder built in servo motor system is for position measurement of crosshead

Load cell

  • High- precision USA-made Transcell load cell offers high stiffness, high stability, and high linearity
  • Over-load protection, lateral loading protection
  • Bi-direction allows tension and compression test
  • Self-recognition (TEDS) function
  • Regular self-calibration
  • Working temperature: -55℃~90℃

Controller

WANCE DTC-500 digital controller offers high speed and closed loop control of load, displacement and extension.

  • Imported IC, more reliable
  • Up to 1200Hz sampling frequency
  • Up to 1200Hz closed loop control frequency
