1.前言 在新干线铺设长钢轨的焊接作业中,对焊接接头产生的焊接凸量,必须进行铣削作业。 过去,这项作业主要用砂轮进行手工操作,是一项需要很多劳力而效率又非常低的作业。而且,由于焊机得到改进,缩短了焊接时间,为使焊接凸量铣削作业与之相适应,研制了带铣刀的高效焊接凸量铣削机。 下面介绍有关焊接接头全周铣削机的概
1. Introduction In the welding operation of laying a long rail on the Shinkansen, welding operations must be performed on the welding bumps produced by the welded joints. In the past, this operation, which was mainly carried out manually by grinding wheel, was a very inefficient and labor-intensive operation. Moreover, due to the welding machine has been improved, shortening the welding time, in order to make the welding convex milling operations and adapt to the development of a milling cutter with high efficiency welding convex milling machine. The following describes the welding joints full circumference milling machine
