Hardness Testing Machine (Hardness Tester)
Digital Rockwell Hardness Tester, Model : RASNE-3
Digital Rockwell Cum Superficial Hardness Tester, Model : RASNET-3
Digital Rockwell Cum Brinell Hardness Tester, Model : RASNEB-3
Features - Hardness Testing Machine
- This is a motorized machine having an automatic loading/unloading cycle suitable for production testing.
- The machine body has a taper front look and a large size read-out in the front. The machine is powder coated for a better look. The paint shade does not fade and the machine looks like new over years.
- The elevating screw of the machine is guided in a hardened and ground bush, not allowing movement of the elevating screw more than 0.05 mm when raised to full height. The accuracy is retained for years together due to the hardened bush.
- A hardened and ground stepped bush is fixed on top of the main screw for location and rest surface. This guarantees no change in results due to rough handling of the test table or test piece. It means a trouble-free long life machine accuracy.
- An antifriction linear bearing with almost no clearance is provided for perfect vertical movement of the loading plunger with minimum friction. This enables testing of small dia. pin or ball up to 3 mm dia.
- These models are provided with an automatic working cycle and digital LCD display with 0.1 Rockwell resolution. This ensures productivity with better accuracy.
- IS:1586 (Part 2) 2012 for Rockwell and Rockwell superficial test. IS:1500 (Part 2) 2013 for Brinell hardness test.
Principle - Hardness Testing Machine
Rockwell, Rockwell superficial& Rockwell cum Brinell test 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.
RASNE series machines are suitable for Rockwell, Rockwell superficial& Rockwell cum Brinell tests. These are motorized digital Hardness Tester having LCD display for easy hardness measurement. The results are displayed in 0.1 Rockwell unit for more accurate measurement.
Operation - Hardness Testing Machine
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.
