Internal traverse grinding (ITG) has shown its great potential in precision machining of valves in fuel supply systems. When grinding such valves, long grinding wheels with small diameter are necessary. However, the poor stiffness of grinding wheels causes large deflection of wheel quill during grinding, resulting in deviation between nominal radial feed …

Valve lifters play a key role in the valvetrain of pushrod engines. They go all the way back to the earliest days of the internal combustion engine. The earliest engines did not have pushrods or rocker arms. They were a "flathead" design with the valves in the block. The lifters (also called "tappets" because of the clattering noise they produced) rode on the cam lobes in …

Spin the drill slowly to grind the valve in its seat. Work the drill in both directions, both forward and backwards. Slowly slide the valve in and out of its seat to move around the grinding compound. You will notice that after a few minutes, the valve spins with less resistance. The grinding compound will be worn down.
