Motorized Turret Touch Screen Brinell Hardness Testing Machine with Automatic Measurement
Brief Introduction:
iBrin-414T Three indenters digital Brinell hardness tester adopts
precise structure design and the load of test force is controlled
by the sensor, which makes the whole structure compact and loading
of test force stable and exact.
All the parameters can be showed and set on the touch screen with
easy operation.
The test process is controlled by CPU, using automatic switching
between the objective and the indenter.
The location of switching adopts mechanical and electronic double
matching, makes the location precision more high.
The instrument has 10 steps test force and 13 kinds of Brinell
testing scale for arbitrary selection; With three indenters and two
objectives, all can be used for measurement, automatic recognition
and shifting between the objectives and the indenter;
Pre-set the dwell time of test force and regulate the luminosity of
light source; Automatically display the testing indentation length,
hardness value and testing numbers; Conversion scales of different
kinds of hardness;
Test results can be saved for checking or be printed out by the
built-in printer, and with RS232 interface for connecting to the
computer.
Available to install optional video measuring device and CCD image
automatic measuring system.
Application range:
Suitable for cast iron, steel products, nonferrous metals and soft
alloys etc. Also suitable for some nonmetal materials such as rigid
plastics and bakelite etc.

Brinell hardness test method:
The Brinell hardness test method consists of indenting the test material with a 10 mm diameter hardened carbide ball subjected to a load of 3000 kg. For softer materials the load can be reduced to 1500 kg or 500 kg to avoid excessive indentation.
The full load is normally applied for 10 to 15 seconds in the case of iron and steel and for at least 30 seconds in the case of other metals. The diameter of the indentation left in the test material is measured with a low powered microscope. The Brinell harness number is calculated by dividing the load applied by the surface area of the indentation.
The diameter of the impression is the average of two readings at right angles and the use of a Brinell hardness number table can simplify the determination of the Brinell hardness. A well structured Brinell hardness number reveals the test conditions, and looks like this, "75 HB 10/500/30" which means that a Brinell Hardness of 75 was obtained using a 10mm diameter hardened steel with a 500 kilogram load applied for a period of 30 seconds.
On tests of extremely hard metals a tungsten carbide ball is substituted for the steel ball. Compared to the other hardness test methods, the Brinell ball makes the deepest and widest indentation, so the test averages the hardness over a wider amount of material, which will more accurately account for multiple grain structures and any irregularities in the uniformity of the material. This method is the best for achieving the bulk or macro-hardness of a material, particularly those materials with heterogeneous structures.
