short info
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.

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.
VSLIC-DRH 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.
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, 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.

One of the key advantages of the SERVO CONTROLLED FULLY AUTOMATIC COMPRESSION TESTING MACHINE is its ability to deliver highly accurate results. This precision ensures that your materials meet the required standards, reducing the risk of costly errors and rework. Moreover, by producing consistent and reliable outcomes, you build a reputation for quality in your industry.
Manufactured as per International design, Plate model for highest mechanical stability, accurate centering of load and excellent repeatability. Fully Automatic pace rate control, auto stop and auto release on failure of test specimen, can be attached with flexural load frame or 500 KN load frame.
Pace rate is achieved manually by controlling the flow control knob and the adjustment can be made by observing the error on the display and the system is released manually after the peak load is achieved.
Rock Cutting Machine can be used to cut cores of varied sizes of concrete, stones, other building materials and metallic specimens.
