我厂承制的一批链轮,在插床或刨床上加工都达不到精加工的要求,后来改在滚床上铣出。但在滚床上铣制,由于工件牙形大,制造铣刀很成问题;如果用碳钢来制造,怕铣刀使用寿命短,用高速钢又没有这么大的料。于是我们就采用碳钢做刀体、再镶上高速钢刀片制成镶片铣刀来应用。这种铣刀的制造过程是这样的: I plant a group of sprockets, in the slotting machine or planer processing are not up to finishing requirements, and later changed in the rolling bed milling. However, milling in the rolling bed, because the workpiece tooth shape, making milling cutter is a problem; if the carbon steel to manufacture, afraid of short life cutter, with high-speed steel and not so big material. So we use carbon steel body, then insert high-speed steel blades made of insert cutter to apply. This milling cutter manufacturing process is this:
