Basic machine design & operation similar to Al B-3000(H). In addition, an ‘optical device’ with 14 x Magnification provided in front to project dia of ball impression on glass screen with a micrometer measuring system with 0.01 mm accuracy. The indenter sweivels & projects dia of ball impression immediately after unloading operation which avoids additional time for measurement of ball impression. This gives real Brinell number on production testing.

Machine designed with a hydraulic power pack and control circuit for effortless loading unloading operation. A dial gauge in front measures depth of ball penetration. This facilitates production testing within tolerance limits by compression method.

Rockwell & Rockwell Superficial 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 and Rockwell superficial 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 witch 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.

ADITYA'S new 'RASNE' series of Hardness Testing Machines come with much improved design & look with following major design changes.

• This is a 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 and 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 brush is fixed on top of main screw for location and 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 3mm dia.
• Both models are provided with automatic working cycle and digital LCD disply with 0.1 Rockwell resolution. This insures productivity with better accuracy.
• Both models conform to IS:1586, BS 10109-2 & ASTM E-18 for Rockwell and Rockwell Superficial Test.
