我厂原生产的C8904铲床是在测绘苏联1810小模数铲床的基础上设计成功的。该机床用来加工模数0.03～0.08的圆盘铣刀和齿轮滚刀等的铲齿机床,目前在国内工具、手表、仪器等行业应用比较广泛。该机床的铲齿工作原理如图1所示。它基本由两个油缸、楔块、杠杆等机构组成。开始工作时,油泵将油同时送入油缸6和7。油缸 Our original factory C8904 shovel bed is designed on the basis of the Soviet Union 1810 small modulus shovel bed design success. The machine tool used to process the mold 0.03 ~ 0.08 disc cutter and gear hobs and other shovel machine tools, tools, watches, equipment and other industries in the country is currently widely used. The machine tool shovel tooth working principle shown in Figure 1. It basically consists of two cylinders, wedges, levers and other institutions. When it starts to work, the oil pump feeds oil to cylinders 6 and 7 at the same time. Cylinder
