该厂自行设计制造的SFll半自动螺旋花键铣床,主要用于加工7655凿岩机螺旋棒(换夹具后可加工活塞)。此机床工作台进给,夹具分度,顶尖等均采用液压驱动,结构简单,操作方便,调好刀具后,只需装卸料即可完成全部加工,分度精度在0.1毫米以内,提高生产效率一倍以上,并且摆脱了繁重的体力劳动。主要技术规格主轴中心到工作台面距离 (毫米) 80—180 主轴中心到机床底面高度 (毫米) 1250
The factory design and manufacture of SFll semi-automatic spiral spline milling machine, mainly for processing 7655 rock drill screw rod (after the fixture can be processed for the piston). This machine tool table feed, fixture indexing, top and so are hydraulic drive, simple structure, easy to operate, after adjusting the tool, just loading and unloading material to complete the processing, indexing accuracy of less than 0.1 mm, improve production efficiency More than doubled, and get rid of the heavy manual labor. Main Specifications Spindle center to table surface distance (mm) 80-180 Spindle center to the bottom of the machine height (mm) 1250
