How to machind the steel rooung bar?This articlewill introduce how to machine the steel roound bar surface.
Surface texture is one of the important factors that control friction and transfer layer formation during sliding. Considerable efforts have been made to study the influence of surface texture on friction and wear during sliding conditions.
What's the steel like in the life ? Cold ,bright and sharp.But you need to know that it is black when the steel is produced without any process.The of purpose of surface process is removal of black shell.
This is the surface condition of the steel bar, which is usually designated at the time of order. Generally speaking this ranges from rough hot mill finished in the case of forging bar to very smooth centreless ground in the case of engineering component.
