油缸、气缸的缸孔加工普遍使用的工艺有珩磨、滚压、旋压等。珩磨是磨削的特殊形式,加工的零件与油石之间作旋转和往复两种形式的复合运动,使零件内表面具有较低的表面粗糙度和网状细纹。而此种网状细纹可存润滑液,使零件的接触表面形成很好的液体润滑,减轻了运动表面的磨损。因此,我们认为珩磨是缸孔加工的理想工艺。我厂的油缸材料为27SiMn,硬度HB280左右,内孔公差0.005～0.025mm,直线度
Cylinder, cylinder cylinder processing commonly used processes are honing, rolling, spinning and so on. Honing is a special form of grinding, machining parts and whetstone between the rotation and reciprocation of two forms of complex movement, so that parts of the surface with a lower surface roughness and reticulate fine lines. And this mesh fine lines can be stored lubricating fluid, so that parts of the contact surface to form a good liquid lubrication, reducing the wear on the moving surface. Therefore, we think that honing is an ideal process for cylinder machining. I plant the fuel tank material is 27SiMn, hardness HB280 or so, bore tolerance 0.005 ~ 0.025mm, straightness
