buttress thread

A method of using NC boring machine to machine large internal buttress thread

数控镗床加工大尺寸锯齿形内螺纹

Process and Thread Thread Milling For large internal buttress thread that is away from the end plane, it is unable to be machined by traditional form tools.

远离端面的大尺寸锯齿形内螺纹，无法用传统成形刀加工。

Turning of buttress thread is a high-load-machining method, which places high requirement on the whole system including machine, tool and clamp, especially on the tool.

偏梯形油井管螺纹车削是一种重载切削方式，它对机床、刀具及夹具等整个工艺系统的要求较高，尤其是对刀具性能要求更为苛刻。

Based on the cutting characteristics of buttress thread and the condition of laboratory, we studied the machinability of buttress thread by cutting experiment and finite element method. All the results will provide constructive suggestion for the production of OCTG.

本文基于偏梯形油井管螺纹的加工特点，结合加工现场的实际情况，通过切削试验和有限元仿真方法对BG95-13Cr偏梯形螺纹的切削加工性能进行研究，最终为企业生产提供指导性建议。
