1.聚晶金刚石刀具目前使用状况近10年来,人们采用合成聚晶金刚石加工有色金属取得了良好的效果。目前在汽车和飞机制造业中,各种含硅量高的难加工铝合金部件均可采用聚晶金刚石刀具进行加工。在其它工业部门,诸如车削加工电介铜整流子、石墨电极、凹板印刷辊轮、烧结硬质合金,车削和铣 Polycrystalline diamond tool current status of the past 10 years, people use synthetic polycrystalline diamond processing of non-ferrous metals and achieved good results. Currently in the automotive and aircraft manufacturing, a variety of high silicon content of difficult to process aluminum alloy components can be polycrystalline diamond cutting tools for processing. In other industrial sectors, such as turning machined dielectric copper commutators, graphite electrodes, intaglio printing rollers, sintered cemented carbide, turning and milling
