目前在交通部所属的修理工厂内修理轮对和制造车轴时采取组合刀具和焊接刀具。这些刀具的使用寿命低和生产率低。工艺设计室与其它部门一道研制了加工新车轮和运用过的车轮踏面用的先进刀具结构。它用来取代三刃刀片机械夹固车刀,波兰Rafamet公司的ИCB—125和ИBC—150型车轮车床都装备有这种车刀。新刀具的刀夹内用差动螺钉和压板固定有一个装有专用刀片的刀盘,刀片为带有压
At present, a combination of tools and welding tools are adopted when repairing wheelsets and manufacturing axles in repair shops owned by the Ministry of Communications.
