自贡硬合金厂采取自力更生与引进改造相结合的方式,经过“七五”期间的努力,建成了一条全新的硬质合金生产线,已成为我国主要的硬质合金可转位刀片生产基地之一。该厂生产的可转位刀片,成型技术先进,采用断屑槽为可变截面、弧形刃口、刀尖强化等特殊结构,具有排屑流畅、断屑范围广、切 Zigong hard alloy plant to take self-reliance and the introduction of transformation combined with the way, after “seven five” during the efforts to build a new carbide production line, has become China’s main hard alloy indexable blade production base. The factory production of indexable blade, forming advanced technology, the use of chip breaker for the variable cross-section, arc edge, tip reinforcement and other special structures, with a smooth chip, chip breaking a wide range of cutting
