本刊通讯员报道,株洲硬质合金研究所最近已成功地研制生产出整体硬质合金球面铣刀。球面铣刀是加工飞机蜗轮叶片、模具和螺杆等零件的理想工具,以往我国均用高速钢制成,用户多数均向国外进口硬质合金球面铣刀。株洲硬质合金研究所研制的硬质合金球面铣刀,不但填补了国内空白,还替代了进口产品。 Correspondents reported that Zhuzhou Cemented Carbide Institute has recently successfully developed and produced a solid carbide spherical cutter. Spherical cutter is the ideal tool for processing aircraft worm blades, molds and screws and other parts, in the past China are made of high-speed steel, the majority of users are imported carbide ball milling cutter. Cemented carbide Institute of Cemented Carbide milling cutter developed, not only to fill the gap, but also to replace the imported products.
