Application & Operation
This machine is used to test the fatigue strength of materials and to draw S-N diagram ideal equipment for Technical Institutions, Research Institutes, Laboratories etc. This is a rotating beam type machine in which load is applied in reversed bending fashion. The standard 8 mm dia specimen is held in special holders at its ends and loaded such that it experiences a uniform bending moment. The specimen is rotated at 4200 RPM by a motor. A complete cycle of reversed stresses in all fibers of the specimen is produced during each revolution. The bending moment is applied with a lever system and can be easily changed by moving a weight over the lever. Total number of revolutions at which the specimen fails are recorded by a mechanical counter. An interlocking system puts off the motor at specimen failure. Machine meets requirements of International / Indian Standards

Features

  • Light weight, compact size, simple design
  • Table model, no need of foundation
  • Simple lever system for changing load
  • Accurately calibrated as per IS 5075
  • Calibration in Nm available on request 8 digit electronic counter instead of mechanical counter can be supplied at additional price and the model is termed as FTG-8 (D).

Machine with maximum bending moment upto 400 kg cm can be offered on request.
