YQ150型潜孔钻钎头是易损件(图1)。国内各专业厂多采用多道模压→机加工→热处理→磨削柄部→焊合机片工艺来生产钎头,钎头的四排浆槽需机加工。我厂以模锻成形、机加工、热处理、磨削、焊片等工序、来完成,钎头四排浆槽锻成后不再机加工,其工艺定型、质量稳定,月产300～500只,满足了本矿生产需要。 YQ150 DTH drill bit is wearing parts (Figure 1). The domestic professional factory to use multi-channel multi-channel molding → machining → heat treatment → grinding shank → welding machine process to produce the first bit of solder, solder head of the four rows of slots to be machined. I plant to die forging, machining, heat treatment, grinding, welding films and other processes to complete the first four rows of bits after the slot is forged machining, the process stereotypes, quality and stability, producing 300 to 500 per month , To meet the needs of the mine production.
