在加工金刚石钻头和扩孔器的丝扣时,为了保证钻具的同心度和加工时不损坏金刚石胎体,我队制造了专用的夹具。这两种夹具都是利用锥套的涨大或缩小的作用,将钻头或扩孔器夹紧,提高了机加工质量和生产效率。构造见图1、2示。 In machining the bits and bits of diamond bits and reamers, I manufactured a special clamp to ensure the concentricity of the drill and to prevent damage to the diamond matrix during machining. Both of these clamps use the effect of the taper sleeve to increase or decrease, which clamps the drill bit or reamer to improve the machining quality and production efficiency. Structure shown in Figure 1,2 shows.
