波形螺纹常用于钎具的连接。其形状、尺寸及配合公差在国际标准中有明确的规定,并规定为左旋螺纹。切制波形螺纹要以螺纹的形成原理为依据,切成的螺纹牙形曲线应与螺纹真形(螺纹牙形曲线的方程组)高度相符。波形螺纹的加工方法有多种,本文只讨论偏心旋削和曲柄车削,并以加工外螺纹为讨论基础,内螺纹的加工同理。 Wave thread commonly used in solder connections. Its shape, size and tolerances in the international standards have a clear rule, and provides for the left-hand thread. Cut wave thread to thread formation principle to be based on the cut thread profile should be consistent with the true shape of the thread (thread shape curve equation) height. Waveform thread processing methods are many, this article discusses only the eccentric rotation and crank turning, and the processing of external thread for the discussion, the same thread processing.
