Other Details

Industrial Fatigue Hardness Testing Machine is used to test the fatigue strength of materials and to draw S-N diagram by research institute, laboratories, material manufacturers and various industries. This is 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 located 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 the lever system and can be easily changed by moving a weight over the lever. Total number of revolution at which the specimen fails are recorded by a mechanical counter. An interlocking system puts off the motor at specimen failure. Machine meets requirement of IS 5075-1969. 

The other features are:

6 digit electronic counter instead of mechanical counter can be supplied at additional price.

Machine with maximum bending moment up to 400 Kg. cm can be offered on request.
