Canan Testing Machines And Calibrations LLP

We are the leading organization actively occupied in providing an extensive series of Portable Hardness Tester. Portable Hardness Tester is developed to meet the demands of a light weight instrument which can be used to carry out tests by auniversally recognised method of Hardness testing.

Rockwell Method: This hardness tester can be used in variety of
applications and is radially adjustable to a wide range of sizes and
shapes which are difficult to test in a standard table model hardness tester. The machine is designed for carrying out Rockwell tests comparable to table model hardness tester because,
the basic things such as shape of penetrator, method of
penetration, measurement and loads are same in both systems.
The photograph of backside gives the general arrangement of the
hardness tester. The system carries a weigh bar (8) pivoted at central point. When the load is applied by the loading screw (9) at one end of the weigh bar, it is deflected and the other end of this bar carrying penetrator forces down into the test specimen. This deflection of weigh bar which is propotional to the applied load is indicated on the loading dial indicator (1 ). Besides this loading dial indicator, there is one penetration measuring indicator (14) which measures the actual penetration of the penetrator into the test specimen is read directly on this indicator. The frame carries two adjusting screws and a gear train. By rotating the knurled knob the distance between the penetrator and the support-anvil can be adjusted.

By keeping track with the modern trends, we are bringing forward a wide series of Analogue Rockwell Hardness Tester to our valued patrons.


Principle:
Rockwell & Rockwell superficial tests consists of forcing an indentor (Diamond or Ball) into the surface of a test piece in two steps i.e. first with
preliminary test force and thereafter with additional test force and then measuring depth of indentation after removal of additional test force
(Remaining preliminary test force active) for measurement of hardness value.
Brinell test consists of forcing a hardened ball into surface of a test piece with a specified test-force and measuring the diameter of indentation
for evaluation of Brinell hardness number.
