Quality Control at LNM Auto

Not be left Behind in show casing how we manage Quality Control we take this opportunity to introduce one of our Quality Control machines for testing hardness-

LNM Auto has installed MIRO HARDNESS TESTER model of M/S CHROMA SYSTEMS. The tester is used for micro loads ranging from 100 gms. to 3000 gms. for estimation of VICKERS HARDNESS using a diamond pyramid indenter. The tester is accomplished by a software computer interfaced for auto measurement and reporting.

The operation involves keeping the polished specimen on the table of the tester and the numbers of impressions by indenter are programmed at fixed interval of the distance from surface. The impressions are measured for two diagonals of the pyramid automatically for Vickers’s hardness. The software gives the graph of Hardness v/s Distance. The effective case depth is automatically calculated by feeding the cut off value in the software.

Major applications involves Effective Core Depth (ECD) measurement of case carburised parts, Decarb & Partial decarb values, hardness of very small and thin parts.
