自锁粘结车刀是用胶结剂将刀片粘结在刀杆上的一种新型刀具。它既能保持刀片原有性能,又可根据不同加工需要,制造、刃磨成各种角度。实践证明,自锁粘结刀制造简单、成本低。近年来,我们对自锁粘结车刀的刀杆结构、粘结工艺、刃磨及使用等进行了研究,并取得了初步成果,现介绍如下。刀杆结构车刀刀片与刀杆的固定,焊接刀是靠铜焊,机夹刀是靠机械夹紧,而自锁粘结刀是靠胶粘剂粘结。但如完全靠现有市场上提供的无机胶粘剂的粘结力是不够的,还要有一定的自锁力。为此,我们分析了外圆车刀在切削加工时的受力情况,将刀杆头上固定刀片 Self-locking adhesive turning tool is a new type of tool that uses a cement to bond a blade to an arbor. It can not only maintain the original blade performance, but also according to different processing needs, manufacturing, grinding into various angles. Practice has proved that self-locking adhesive knives manufacturing simple, low cost. In recent years, we have carried out researches on the structure, bonding technology, sharpening and using of the self-locking knives, and achieved initial results. Arbor structure knife blade and arbor fixed, welding knife is by brazing, machine folder knife by mechanical clamping, and self-locking adhesive knife is bonded by adhesive. However, if it is not enough to rely solely on the adhesion of the inorganic adhesives provided on the existing market, there must be some self-locking force. To this end, we analyzed the cylindrical lathe cutting force, the knife head fixed blade
