Rockwell Hardness Testers

Features :
• This is motorized machine having automatic loading/unloading cycle suitable for production testing.
• The machine body is having a taper front look and large size read-out in the front.
    The machine is powder coated for better look.
• The paint shade do not fade and machine looks like new over years.
• The elevating screw of machine is guided in a hardened & ground bush, not allowing movement of elevating screw
    more than 0.05 mm when raised to full height. The accuracy is retained for years together due to hardened bush.
• A hardened and ground stepped bush is fixed on top of main screw for location & rest surface.
   This guarantees no change in results due to rough handling of 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 a perfect vertical movement of loading
    plunger with minimum friction. This enables testing of small dia. Pin or ball upto 3 mm dia.
• These models are provided with automatic working cycle and digital LCD display with 0.1 Rockwell resolution.
    This insures productivity with better accuracy.
• IS:1586 (Part 2) 2012 for Rockwell and Rockwell superficial test. IS:1500 (Part 2) 2013 for Brinell hardness test.

Features:
• Load cell based close-looped control.
• Brinell, Rockwell, Vickers three testing methods.
• Selection of plastic Rockwell scales (specific demands are supplied depending on the contract).
• Hints for indentors when the scales are selected.
• Automatically apply major load and minor load.
• On screen conversion of hardness scales.
• Result can be exported in “Excel” using flash drive

AROJ Hardness Testers, Model : RAS, RAB-1, RAB-250 & TWIN are manually operated. All these models are suitable for testing hardness of metals & alloys of all kinds hard or soft, whether flat, round & irregular shape. These testers are simple in design & easy to operate, yet sensitive and accurate. Various models from the wide range are suitable for Tech. Institutes, Laboratories, Tool-rooms, Inspection, Heat treatment departments, Factories etc. These testers strictly confirm to IS:1586-2 for Rockwell & Rockwell superficial test.

As a quality-oriented organization, we are focused to provide our clients excellent quality Touch Screen Rockwell Hardness Testing Machine.

Principal :
Digital Rockwell Hardness Testing Machine 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 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' 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.
