“双钼丝环孔型线切割机床”研究项目已于1986年10月30日在市科委主持下通过了专家鉴定验收。该项目由上海第一铜管厂等单位共同完成。这台机床主要加工轧辊的孔型空间曲面,用普通机械加工很难完成,即使完成了还有热处理变形问题。它可在x、y轴移动和z轴旋转,采用了双丝架,双钼丝同时切割,既可提高生产效率,又能保证加工轧辊的质量,若装配专用夹具后,就能加工双线轧机的轧辊,每次可加工四根(一 “Double molybdenum ring hole cutting machine tool” research project was October 30, 1986 under the auspices of the Municipal Science and Technology Commission passed the expert appraisal. The project by the Shanghai First Copper Tube Factory and other units to complete. This machine tool main processing roller hole space surface, with ordinary machining is difficult to complete, even if there are still heat treatment deformation. It can move in the x, y-axis and z-axis rotation, using a double wire frame, double molybdenum wire cutting at the same time, both to improve production efficiency, but also to ensure the quality of processing roller, if the assembly of special fixture, you can process double line Rolling mill, each can be processed four (one
