硬质合金铰刀作为一种高效切削工具问世以来,在国际国内范围越来越广泛被采用。在 ISO 的硬质合金 P,M 和 K 类基础上,我国发展生产碳化钨、碳化钴、碳化钛、碳化钽和钴等材料、规格,突破了高效铰削这一难关。但是,如何正确设计、加工,特别是硬质合金铰刀各参数如何达到合理安排,使其 Carbide reamers as an efficient cutting tool since its inception at home and abroad more widely adopted. On the basis of ISO cemented carbide P, M and K, our country develops and produces tungsten carbide, cobalt carbide, titanium carbide, tantalum carbide and cobalt and other materials and specifications, breaking the difficulty of high-efficiency reaming. However, how to correctly design, process, and especially the parameters of cemented carbide reamers how to make reasonable arrangements
