SINT Technology's MTS3000 Restan residual stress analyzer, available from Durham Instruments

Durham Instruments is Canada’s best source for state-of-the art industrial measuring instruments from manufacturers around the world. One of the latest tools available is the MTS3000 Restan residual stress analyzer produced by SINT Technology, an automatic system designed for measuring residual stress in SINT’s own patented hole-drilling method.

The MTS3000 system is perfectly suited to drilling applications in several industries, including aerospace, manufacturing, medicine, the military, utilities, transportation, research and development, and even education.

The highest measuring accuracy

Residual stresses are stresses that reside in materials before external forces are applied. During hole drilling, residual stress may affect the behaviour of mechanical components, with effects on the dimensional and structural stability of the machines and on the materials’ fatigue and fracture resistance. It can also make drilling machinery unsafe to use and limit its loading capacity.

SINT’s hole-drilling method enables inexpensive yet highly accurate experimental stress analysis. It involves drilling a small hole, usually between 1.8 and two millimetres deep, to spur redistribution of the residual stress in material. The Restan is an essential part of this system.

The MTS3000 includes the following features:

  • an optical alignment system, for aligning the axis to the rosette centre;
  • a high-speed air-turbine drilling system;
  • an electronic control unit, for controlling the alignment-drilling system and the analog amplifiers’ measurements;
  • operating and control software for hole drilling, to enable or disable the automatic drilling; and
  • software to process the acquired data, enabling calculation and determination of residual stress with various methods.

The Restan also has a fully automatic drilling and acquisition process to ensure repetition, automatic stepping motor control of drilling depth, automatic zero-depth detection, and a choice of calculation methods for residual stress and stress profile. The system is fully compliant with the ASTM E837-13a standard and compatible with drilling of up to 400,000 revolutions per minute.

Trust the MTS3000 to make hole drilling safer and more convenient.
