Rockwell Hardness Testing Machine
Hardness Testers Models RAS, RASM, 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 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
- MODEL : RAS : Automatic load selection with automatic
zero setting dial gauge. Manual Operation.
- MODEL : RASM : Similar to ' RAS1 but motorised model.
Semiautomatic operation for production testing. Drive motor single
phase 230V 50 cycles.
- ROCKWELL COMBINED SYSTEM MODEL RAB-1 : Automatic load
selection with automatic zero setting dial gauge. Facility for
rockwell Tests with 187.5 kgf. load with 2.5 mm ball indentor,
additional load 250 kgf. with 5 mm ball Indentor for testing
hardness of non- ferrous metals. Manual Operation.
- MODEL : RAB-250 : Similar to 'RAB-11 but bigger capacity
Diamond Holder is guided in a set of two bail cage, which enables
testing of small pins having dia. less than 6 mm (upto 3mm dia)
- ROCKWELL SUPERFICIAL COMBINED SYSTEM MODEL : TWIN :
Manual load selection with automatic zero setting dial gauge. Manual
Operation. Diamond Holder is guided in a set of two ball cage, which
enables testing of small pins having dia. less than 6 mm. (upto 3 mm

Computerised Rockwell cum Brinell Hardness
Testing Machine -
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.
- This is motorized machine having automatic loading/unloading
cycle suitable for production testing.
- 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.
- 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.
- 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.
- 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
