Brinell Hardness Testing Machine

Brinell Hardness Tester is a production type machine designed for measuring the Brinell Hardness of steels and other metals that are flat, round or irregular in shape. The machine is sensitive, accurate and easy to operate.

The machine consists of a ‘J’ frame, main lever, hanger, elevating screw, loading - unloading mechanism and damper system. The load is applied on the job through a ball indentor. It is applied through a lever mechanism. 

- The main lever carries three male vees one for hanger second for spindle shaft and third for pivot vee. The elevating screw can be moved up and down by rotating hand wheel. There are six detachable weight out of which four are each equivalent to 500 kgf and two are each equivalent to 250 kgf to be made use of for application of desired load in addition to the bottom weight equivalent to 500 kgf. The operating lever is provided for loading & unloading. 
- The damper system consists of main cylinder, piston, valve disc, connecting rod and metering valve. The damping sensitivity is adjusted by the metering valve. The connecting rod and piston is actuated through cam, mounted on cam shaft while operating.
