摘要:: 本文讨论无心贯通磨削中导轮轮廓曲线对加工过程的影响,提出以初等数学的方法推导准确的导轮轮廓曲线的方程式,以及近似导轮轮廓曲线的求法。对苏联В.И.Сло-нимский著《无心磨削的理论与实践》中推导的导轮修正角计算公式提出更为简捷的计算公式。无心磨床是应用较广泛的机床。无心磨床导轮形状是否合乎要求对加工质量及加工过程中工件运动的稳定性有根本性的影响。导轮轮廓曲线及其修整方法一直是无心磨削加工的重要研究课题。

Abstract:: In this paper, the influence of guide wheel contour curve on machining process in centerless through grinding is discussed, and the accurate equation of guide wheel contour curve is derived by elementary mathematics, and the method of approximate guide wheel contour curve is proposed.The paper proposes a more concise calculation formula for the correction Angle of guide wheel derived from the Theory and practice of centerless grinding in Soviet Union.Centerless grinding machine is a widely used machine tool.Whether the guide wheel shape of centerless grinding machine meets the requirements has a fundamental impact on the machining quality and the stability of the workpiece movement during the machining process.Guide wheel contour curve and its trimming method are always important research subjects in centerless grinding.
