目前,在电子工业及其他工业中,为了使所用机器和仪表达到精巧和微型化,需要使用厚度在0.1毫米以下的、高度平整的金属薄板。在多辊校平机上展平很薄或弹性较高的板料,必须减小工作辊的直径,以便材料受到塑性弯曲。但是,辊径减小后,校直机其它部分(例如支承辊列、轴承,连接件等)的尺寸也必然随之缩小;因此,校直机的规格是有一定限度的。目前出现的最小型多辊校直机的辊径不小于5毫米。因此,电子工业所需的那
At present, in the electronics industry and other industries, in order to achieve sophistication and miniaturization of machines and instrumentation used, it is necessary to use highly-flat metal sheets having a thickness of 0.1 mm or less. In a multi-roll leveling machine flattening thin or high elastic sheet, you must reduce the diameter of the work roll, so that the material is subjected to plastic bending. However, as the roll diameter decreases, the size of the rest of the straightener (such as support rollers, bearings, connectors, etc.) inevitably decreases; therefore, the straightener specifications are limited. The smallest multi-roll straightener currently available has a roll diameter of not less than 5 mm. So that’s what the electronics industry needs
