刀具材料在实际应用中的发展落后于研究成果的发展。车、铣加工一般都用硬质合金涂层刀具(有时也用氧化铝涂层)。陶瓷刀片高速切削只在特定条件下,例如在大量生产中的连续切削时使用。在对灰铸铁、钛合金与镍基合金作断续车削或铣削时,真正能提高生产率的是使用氮化硅可转位刀片。热压刀片车、铣灰铸铁的切削速度可达800m/min以上,有时甚至可达1000m/min;车削镍基合金可达300m/min以上,见图1。无孔冷压刀片目前备有三角形、正方形、菱形及圆形等基型。 The development of tool material in practical application lags behind the development of research results. Cars, milling processes are generally coated with cemented carbide tools (sometimes with alumina coating). High-speed cutting of ceramic blades is only used under certain conditions, such as continuous cutting in mass production. In the gray cast iron, titanium and nickel-based alloys for intermittent turning or milling, the real increase in productivity is the use of silicon nitride indexable inserts. Hot pressing blade car, milling gray iron cutting speed up to 800m / min or more, and sometimes up to 1000m / min; turning nickel-based alloy up to 300m / min or more, shown in Figure 1. Non-porous cold blade currently available with triangular, square, diamond and round base type.
