Digital Fatigue Testing Machine

FEATURES

• This machine is light, compact & simple in design used to test the fatigue strength of materials & to draw S-N diagram, used for research institutes, laboratories, material manufacturers & various industries
• Machine is table model, no need of civil foundation
• Rotating beam type machine in which load is applied in reversed bending fashion.
• Standard 8 mm diameter specimen is held in special holders at its ends & 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 fibres 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.
• Maximum bending moment of 200 kgcm is applied & adjustable from 25 to 200 kgcm.
• Total number of revolutions at which the specimen fails is recoreded by a digital counter.
• The total number of digits of digital counter is eight.
• An interlock system puts off the motor immediately after specimen fails.
• Accuracy of applied bending moment ±1%.
• Optional-Machine with maximum bending upto 400 kgcm can also be offered.
• Machine meets requirements of IS:5075-1969.
