Digital Rockwell Hardness Testing Machine

Digital Rockwell Hardness Testing Machine that rolls off our manufacturing unit is fabricated from quality materials to test a wide range of metals and alloys. The machine is set under the supervision of experts and as per the client’s specific requirements. It features an LED bar indicator, which is used for setting the position and ease the operation. Its larger display and convenient handling makes it user friendly. We are emerging as the promising Manufacturer and Supplier of Digital Rockwell Hardness Testing Machine in Maharashtra.  

Features :

• Motorized for automatic operation cycle i.e. load / dwell / unload
• Preliminary Test Force - 98.07N (10 kgf.)
• Additional Test Force - 490.3, 882.6, 1373N (50, 90, 140 kgf.)
• Total Test Force - 588.4, 980.7, 1471N (60, 100, 150 kgf.)
• Test Force selection by external dialing
• Set position with LED bar indicator for easy operation
• Key board entry through reliable membrane switches for scale / GO-NOGO / dwell time selection
• Large size scale display for easy reading with 0.1 Rockwell resolution
• Parallel output for connecting dot matrix printer to get results indicating serial number of tests, hardness scales, hardness value and high / good / low indication

 
Principal :

• Rockwell, Rockwell superficial & Rockwell cum Brinell 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.
• SSS-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.

For Brinell scale - manually select (187.5 or 250 kgf) with respected ball indentor. At that time take reference of set point only. Apply the load, then measure the impression dia by Brinell microscope only. (No Brinell scale display on screen).
