Blue Star E&E provides various types of Brinell Hardness Testing Machines, depending on the operational pattern of the testers and requirements of the users. These machines measure the hardness of a material by pressing a chromium-steel or tungsten-carbide ball against the smooth material surface under standard test conditions. The hardness is expressed in HBW, where the ball indenter is made of tungsten carbide.
Analogue Brinell Hardness Testers are designed with a hydraulic power pack and control circuit to make the loading and unloading operation smooth. Dial gauge measures the depth of the ball penetration.
These machines are engineered precisely to conform IS 1500 (II): 2013, ISO 6506: 2005, BS: 240 and ASTM: E 10. These testers ensure production testing within tolerance limits by compression method. These testers are capable of measuring hardness of castings, forgings, other metals and alloys of all kinds (hard, soft, flat, round or irregular in shape).
Optical Brinell Hardness Testers are very similar to the analogue testers in machine design and operations. In addition, an optical device with 14x magnification is in-built to project diameter of ball impression on glass screen with a micrometer measuring system. It projects the diameter of ball impression immediately after unloading, saving additional time for measurement of ball impression.
These machines are engineered precisely to conform IS 1500 (II): 2013, ISO 6506: 2005, BS: 240 and ASTM : E 10. They are most suitable for production testing, ensuring production testing within tolerance limits by compression method. The testers are capable of measuring hardness of castings, forgings, other metals and alloys of all kinds (hard, soft, flat, round or irregular in shape).
Computerised Brinell Hardness Testers measure Brinell Hardness Number directly and accurately, using state-of-the-art image processing technology. An in-built camera captures the image of the impression on the specimen and displays on the monitor. The software calculates the diameter (manual/semi-auto/auto) and converts it into measured hardness value. The software also segregates low/high and performs statistical evaluation. Repeated measurements at all loads yield higher productivity. Options for data storage and reports generation are also provided to save time.
They have algorithms for precise calculation of hardness numbers with various options to cover all ranges of specimen. These testers strictly conform to IS 1500(II): 2013, ISO 6506: 2005, BS: 10003-2 and ASTM E-10. The testers are suitable for measuring the hardness of metallic parts from soft to hard.
Semi-automatic Brinell hardness testers are flexible testers which can use multiple output methods, unlike other testers. Here, the reading of indentation is made through standard microscope or through optional electronic microscope with auto-measure.
Fully Automatic Brinell Hardness Testers are fabricated from steel plates and are designed for precise loading systems. Once the job is placed on the testing table and “Cycle Start" button is placed, it takes care of all the operations till the job is lowered down at the end of auto cycle. Operationally the machine can be operated without the push button, so that user has to do only loading and unloading of jobs on the machine. The diameter of indentation is measured by PC and the Brinell Hardness is displayed on the monitor.
These testers strictly conform to IS 1500 (II): 2013, ISO 6506: 2005, BS: 10003-2 and ASTM E-10. The testers are fully automatic machines for production testing and are suitable for measuring the hardness of metallic parts from soft to hard.
