Introduction of Rockwell hardness testing machine

            The Rockwell hardness testing machine is a popularly-used hardness testing instrument to measure the Rockwell hardness of the materials. The speed of loading the test force is regulated by the buffer whereas the change of the test force is made by rotating the carriage-changing hand-wheel. The operation of the present instrument is simple, its functions are stable, and its use is, therefore, widely spread.

            It's suitable to determine the Rockwell hardness of ferrous, non-ferrous metals and non-metal materials. It can be widely applied in the Rockwell hardness testing for heat treatment materials, such as quenching, hardening and tempering, etc.

Characteristics of Rockwell hardness testing machine

1.Manual testing process, no need for electric controlling

2.It's steady and reliable for testing of curved surface

3.Precision conforms to the Standards of GB/T 230.2, ISO 6508-2 and ASTM E18

 

Advantages of Rockwell hardness testing machine    

1.Lever Loading, manual operation, durable and reliable.

2.No friction spindle, high precision test force.

3.Precision hydraulic buffers, steady load.

4.Dial display the hardness value, HRA, HRB, HRC, and can choose other Rockwell Scale.

5.Accuracy according to GB / T230.2, ISO 6508-2 and American ASTM E18 standard.
