孔的精加工,特别是小孔的精加工在许多工厂已经成为急需解决的—个中心课题。目前我国采用的普通钻孔、拉孔、铰孔由于存在光洁度差,精度不高,工具寿命短等问题,而难以实现高效高质量的精加工。对于难加工材料,这些问题就表现得更加突出,因而严重地影响了新材料的使用和新产品的开发,为此,我们介绍一下日本的振动精密铰孔。 Hole finishing, especially hole finishing, has become an urgent need in many factories - a central topic. At present, ordinary drilling holes, pull holes and reaming holes used in our country are difficult to achieve high-efficiency and high-quality finishings due to the problems of poor finish, low accuracy and short tool life. These problems have become more prominent for difficult-to-machine materials, which has seriously affected the use of new materials and the development of new products. To this end, we introduce Japan’s vibrating precision reaming.
