求翻译：轧纹精度可控制在相邻节距的节距误差不超过1mm，同一环内深度偏差不超过0.5mm（以铝护套壁厚均匀，厚度偏差不大于0.5mm为前提）；是什么意思？

Corrugating accuracy can be controlled in the adjacent pitch pitch error of not more than 1mm, depth deviation in the same ring does not exceed 0.5mm (aluminum sheath wall thickness, the thickness deviation of not more than 0.5mm);

Rolls over the grain precision to be possible to control in the neighboring pitch pitch error does not surpass 1mm, in the identical link the depth deviation does not surpass 0.5mm (to be even by aluminum protective covering wall thickness, thickness deviation is not bigger than 0.5mm is premise);

Corrugating accuracy can be controlled in the adjacent pitch pitch error of less than 1mm, DO not exceed 0.5mm within the same ring (aluminum-sheathed wall thickness uniformity, the premise of thickness deviation of not more than 0.5mm);
