Manufacturing Process
The various activities involved in manufacturing J/L/I Bolts are:
Incoming raw material inspection using Brine cum Rockwell hardness tester.
Cutting to size of alloy steel bars.
Chamfering of ends.
Centreless grinding of pre roll diameter. This operation ensures accuracy of threads formed subsequently.
