Rocker arm shaft is an important component in internal combustion engine and some motor drive system, rocker arm shaft occupies a key position in the work of the engine, and can affect the performance, power and efficiency of the engine. The structure of rocker arm shaft usually contains several deep holes (e.g. lubrication holes, valve connection holes, etc.) with high surface roughness requirements. Deep hole drilling machine is capable of machining deeper holes, which is suitable for longer holes in the rocker arm shaft. Its special design makes it possible to maintain good machining stability and dimensional accuracy during deep hole machining. The combination of suitable deep hole drilling tools and deep hole drilling machines can maximize the machining efficiency and precision and ensure the quality of the rocker arm shaft.
