middle duty live center

Study on deflection of high precision rotating center with heavy-duty based on finite element;

基于有限元法的高精度重型回转顶尖挠度的研究

The method of screw thread turning finial straining workpiece,reverse feeding,and rough turning and then finish turning are introduced in this paper.

介绍了采用螺纹回转顶尖拉紧工件,反向走刀,粗、精车刀进行加工的方法,来加工细长杆类工件,扩大了设备的加工能力,提高了设备的利用率。
