The floor-mounted, durable body ensures stable measurements, while manual and optical control modes provide flexible operation. With its instant response and precise optical readings, the instrument is ideal for labs, manufacturing units, and research applications requiring accurate hardness verification.

Optical Precision and Safety Features

A 20x magnification optical microscope paired with a precision measuring scale enables meticulous evaluation of indentation. Adjustable dwell time, overload protection, and safety interlocks guarantee safe, repeatable testing, mitigating operator errors and equipment damage. This combination of safety and precision makes it suitable for high-stakes quality control in engineering and metallurgy.

FAQs of OPTICAL BRINELL HARDNESS TESTING MACHINE:

Q: How does the Optical Brinell Hardness Testing Machine operate?

A: The machine functions using either a hardened steel or tungsten carbide ball indenter. Users can select manual hand lever or automatic weight loading modes. After specimen placement, the indenter is applied with up to 3000 kgf, and the dwell time is set between 10 and 30 seconds before reading the indentation under a 20x optical microscope.

Q: What applications are ideal for this Brinell hardness tester?

A: This equipment is specifically built for metal hardness testing in industrial environments such as quality control labs, steel manufacturers, and metalworking plants. It accommodates single specimens up to 250 mm in height and is suited to materials within the 8650 HBW hardness range.

Q: When should I adjust the dwell time during testing?

A: Dwell time should be adjusted according to the materials hardness and industry standard testing protocols. Softer materials may require longer dwell times up to 30 seconds, while harder metals typically need shorter durations closer to 10 seconds for optimal results.

Q: Where can the Optical Brinell Hardness Testing Machine be installed?

A: This floor-mounted machine is suitable for installation in laboratories, manufacturing facilities, engineering workshops, and production areas with stable surfaces. The standard port size and operating temperature range (10C40C) allow flexibility in most industrial environments.

Q: What is the process for measuring hardness with this machine?

A: Place the specimen, set the indenter type, select manual or automatic weight loading, adjust dwell time, and initiate indentation. After the set dwell period, observe and measure the indentation diameter using the optical microscope and precision scale, then derive the Brinell hardness value.

Q: How does the machine ensure safe operation during testing?

A: Safety is ensured through integrated overload protection and safety interlocks. These mechanisms prevent equipment damage and operator injury, ensuring the device operates only under safe and correct conditions.

Q: What are the benefits of using an optical microscope in hardness testing?

A: The 20x optical microscope provides high-resolution measurement of indentation diameter, resulting in increased accuracy (0.5%) and reproducibility. This promotes reliable quality control, reduces measurement errors, and enhances confidence in test results.
