Rocker arm is an oscillating lever in an engine. It’s one end is raised which is lowered by a rotating lobe of the camshaft while the other end serves to work on a valve stem. We take care of the wear resistance with chilled cast iron along with heat treatment and attain just the perfect surface roughness by controlling metal cutting parameters. In crux this is the way we manufacture rocker arms.
