HARDNESS TESTING MACHINES - SERIES - RASN
|
|
|
| |
Principle |
| |
Rockwell & Rockwell superficial tests consist 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.Brinell test consists of forcing a hardened ball into surface of a test
piece with a specified test-force and measuring the diameter of
indentation for evaluation of Brinell Hardness number. |
|
|
| Operation |
| |
For Rockwell & Rockwell superficial Test: |
In case of 'RASN' series machines for Rockwell or Rockwell
superficial tests, a preliminary test force is first applied without
removing zero. Quickly thereafter an additional test force is applied
without removing the preliminary test force. When the penetration is
stabilised, the additional test force is removed and the hardness
number is shown directly on the indicator |
| |
| For Brinell Test |
| |
For Brinell Test :
The operation is exactly same as above. However, the diameter of
impression is measured out side of machine by Brinell microscope.
Brinell hardness number is found out by refering corresponding
hardness tables showing hardness number against dia. of
indentation for specified ball diameter and test force |

|
Adinath's new 'RASN' series of Hardness Testing Machines come with much improved design and look with following major design changes. |
| |
| 1) |
The machine body is having a taper front look and a big size dial gauge in the front. The machine is powder coated for far better look. The paint shade do not fade and machine looks like new over Year |
| 2) |
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 |
| 3) |
A hardened and ground stepped bush is fixed on top of main screw
for location and test 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 |
| 4) |
An antifrication linear bearing with almost no clearance is provided or a perfect vertical movement of loading plunger with minimum This enables lesting of small dia. pin or ball upto 3 mm dia |
| 5) |
All machine models are provided with automatic zero setting dial
gauge or digital readout. Hence zero setting at every test is
avoided |
| 6) |
All four models confirm to respective standard as under.
