Rockwell Hardness Testing Machine - (SICMRHT-01)
Hardness Testers Models SI RAS, SI RASM, SI RAB-1, SI RAB-250, SI TWIN are manually operated. All these models are suitable for testing hardness of metals & alloys of all kinds hard or soft, whether flat, round or irregular in shape. These testers are simple in design & easy to operate, yet sensitive & accurate. Various models from the wide range are suitable for Engg. Colleges, laboratories, toolroom, inspection departments, factories etc. These testers strictly conform to IS: 3804-1988, BS: 891 parts 1&2, ASTM:E18 for Rockwell Test, IS: 2281-1983, BS: 240, ASTM:E10 for rockwell Test & IS: 5073-1988, ASTM:E18 for Rockwell Superficial Test.
Salient Features

Computerised Rockwell Cum Brinell Hardness Testing Machine

Computerised Rockwell Cum Brinell Hardness Testing Machine
Computerised Rockwell cum Brinell Hardness Testing Machine - (SICMRHT-02)
IS: 1586:2000 for Roackwell and superficial test. 13:2281:2005 for Brinell Hardness Test. Rockwell cum Brinell tests consists of forcing an indentor (Diamond 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 addition test force (Remaining preliminary test force active) for measurement of hardness value. These machines are suitable for 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. Brinell Hardness measured by using microscope manually.
Salient Features
  • 1. This is motorized machine having automatic loading/unloading cycle suitable for production testing.
  • 2. The machine body is having a taper front look and a 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.
  • 3. 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 accessory is retained for years together due to hardened bush.
  • 4. A hardened and groung stepped bush 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.
  • 5. 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.
  • 6. These models are provided with automatic working cycle and digital LCD display with 0.1 Rockwell resolution. This insures productivity with better accuracy
