ELECTRONIC HARDNESS / ROCKWELL HARDNESS TESTER



PRINCIPLE :

Rockwell, Rockwell superficial& Rockwell cum Brinell test consists offorcing 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.
RASNE series machines are suitable for Rockwell, Rockwell superficial& Rockwell cum Brinell tests. These are motorized digital Hardness testers having LCD display for easy hardness measurement. The results are displayed in 0.1 Rockwell unit for more accurate measurement.

OPERATION :

Various parameters of test can be set on front panel by operation of key board and observing LCD display Viz high/low limits, dwell time, auto/manual start, printer selection, scale selection etc. All set data can be verified edited by pressing SCL key one after another.
Machine operation is very simple. The normal mode is a bar followed by "SET" indication. Raise elevating screw slowly through bar indication till "SET" position which will show "PRESS START" indication. Now press "START" button. Loading/unloading cycle will be completed and hardness is shown on LCD display with high/Good/Low indication. Lower down elevating screw. Panel will show normal mode for next test. Also when required 'AUTO START' set 'AUTO START' on front panel by operation of key board & observing LCD Display then raise elevating screw slowly through bar indication till "SET" position then it will starts loading/unloading cycle automatically & hardness is shown on LCD Display with High/Good/Low indication.
