不锈钢方管和工具电极表面

众所周知,普通电化学抛光的加工间隙通常设定为100-300mm,但由于小直径不锈钢方管内径的尺寸限制,这显然是不可能的。对于这种小间隙加工,工具电极的表面粗糙度不同,并且不锈钢方管和工具电极表面上的点之间的加工间隙也改变。
It is well known that the machining gap of conventional electrochemical polishing is usually set at 100-300 mm, but it is obviously impossible because of the size limitation of small diameter stainless steel square pipe. For this kind of small gap machining, the surface roughness of tool electrodes is different, and the processing gap between stainless steel square pipe and the points on the tool electrodes surface is also changed.
加工间隙将直接影响相应位置的电流密度。在间隙大的地方,电流密度相对较低,材料去除率低,并且在小的加工间隙中电流密度相对较大,并且材料去除率高。
Machining clearance will directly affect the current density of the corresponding position. Where the gap is large, the current density is relatively low, the material removal rate is low, and the current density is relatively high in the small processing gap, and the material removal rate is high.
因此,工具电极表面的微观几何形状在抛光的不锈钢方管表面上形成不同的复制程度。
Therefore, the micro-geometry of tool electrode surface forms different replication degrees on polished stainless steel square pipe surface.
