兰州曙光机械厂大搞技术革新和技术改造,仅用四个月的时间,就设计制造出一台机械式抛光机,用于抛光筒体内壁。被抛工件放在工作台上,以四个托轮支承并旋转,抛头能平行移动和上下移动,完成抛削动作。该机能抛光直径为400～2500毫米,长2米以下的各种圆筒体内壁,可大大减轻工人劳动强度,改善了劳动环境,保证了 Machinery plant in Lanzhou Dawn engage in technological innovation and technological innovation, only four months time, to design and manufacture of a mechanical polishing machine for polishing the inner wall of the cylinder. The workpiece was thrown on the workbench to support and rotate four wheel support, throwing head can move in parallel and move up and down to complete the polishing action. This machine can polish the inner wall of various cylinder with diameter of 400 ~ 2500mm and length of 2m, which can greatly reduce labor intensity, improve working environment and ensure
