| 摘 要： | 为了加工大直径零件上的大导程多头梯形内螺纹,需将CQ5250立车改造为西门子数控系统的数控车床。根据周向分度法基本原理进行分度,采用斜向单面车削与左右扩削相结合的加工方法,利用所编制的加工程序加工大直径大导程多头左旋梯形内螺纹,既能够保证螺纹的加工精度,又可以减少刀具重磨和重定位次数,缩短辅助时间,提高生产效率。

| Abstract: | In order to machine steep-lead multiple-trapeziform screw thread of large diameter parts, CQ5250 vertical lathe is modified to suit siemens numerical control system lathe. According to the method of circumferential indexing, by using the machining method of the slant single-sided turning and left-right combined, by using numerical control machining procedure, large diameter and steep-lead multiple-trapeziform screw thread is worked. The method not only guarantees the machining precision, but also reduces the times of the cutter regrinding and reorientation, reduces accessorial time, and improves production efficiency. |
