小口径金刚石钻进,有时为了补取岩(矿)芯或为了避开孔内事故钻具,需要偏斜钻进.过去常用管材加工偏斜器,这种偏斜器在偏斜钻进过程中或工作一段时间后容易磨透“肚子”. 我队车间利用废钢料浇铸偏斜器.铸钢偏斜器具有耐磨、坚固的优点.由于浇铸的偏斜器表面比较粗糙,使用前应在车床上进行机加 Small-diameter diamond drilling, sometimes in order to make up the rock (ore) core or in order to avoid the accident hole drilling tools, need to skew drilling. In the past often used pipe processing deflection, this deflection in the process of deflection drilling Or in the work after a period of time easy to penetrate the “belly.” Our team workshop using waste steel casting skew. Casting steel skew has the advantages of wear-resistant, strong. Due to the cast surface of the ramp is relatively rough, before use should Machine on the lathe
