GRINDING MACHINES Grinding is the process of removing metal by the application of abrasives which are bonded to form a rotating wheel. When the moving abrasive particles contact the workpiece‚ they act as tiny cutting tools‚ each particle cutting a tiny chip from the workpiece. It is a common error to believe that grinding abrasive wheels remove material by a rubbing action; actually‚ the process is as much a cutting action as drilling‚ milling‚ and lathe turning. The grinding machine supports and

Short essay on The Bhopal Gas Tragedy JAYAPRAKASH KAKADA By all accounts the Bhopal Gas leak on the night of 2-3 December 1984 is the worst chemical disaster in history. It took a heavy toll of human lives. People started dying within hours and more than 2000 lives were lost in the first few days. According to Dureja and Saxena one of the earliest of the ’Rescue Teams’ to reach Bhopal when panic was at its peak at major hospitals of the city‚ the patients could be graded symptomatically into four
