我国多数中小机械加工企业,尤其是单件小批量生产单位,普遍应用普通卧式镗床。在这类镫床镗孔加工中,多年来主要沿用传统的加工方法,即径向进刀仍然靠“磕刀头”,这种方法要求工人技术高,经验丰富,但生产效率低。近年来随着机械加工刀具技术的发展,不同程度地装备使用了各种微调镗削刀具,由于受刀具加工范围等因素影响,在普通镗床上推广应用仍有一定局限性。结合生产实际我厂设计试制了径向微调刀杆(见附图)。此刀杆是一种新型镗杆结 Most small and medium-sized machinery processing enterprises in our country, especially single small batch production units, commonly used ordinary horizontal boring machine. In this type of billet boring process, the traditional method of machining has been used for many years. That is, the radial infeed still depends on the “knock head”. This method requires workers to be highly skilled and experienced, but their production efficiency is low. In recent years, with the development of machining tool technology, different degrees of equipment to use a variety of fine-tuning boring tool, due to the scope of the tool processing and other factors, to promote the use of ordinary boring machine still has some limitations. Combined with the actual production of our factory trial design of a radial fine adjustment Arbor (see photo). This knife bar is a new boring bar knot
