本成果研制的新型高效铲齿成型铣刀与传统结构的成型铣刀不同 ,具有螺旋齿和飞前角。能逐渐切入和逐渐切离工件 ,切削平稳、噪声低、效率大幅度提高 ,切削力成倍下降。本成果已获专利。无论在成型铲齿刀具设计和制造的理论或在生产技术实践方面都有重大创新。生产考核证明 ,理 The results of the development of a new type of highly efficient cutter blade milling cutter structure with the traditional structure of different, with helical teeth and fly-front angle. Gradually cut into and gradually cut off from the workpiece, cutting smooth, low noise, greatly increased efficiency, cutting force doubled. This result has been patented. No matter in the theory of forming and cutting tool design and manufacture, or in the production technology practice, there are significant innovations. Production examination proved that management
