异型轧辊的计算机数控包络磨削法

The CNC Enveloping Grinding Method for Complex Contour Roll

钢管行业广泛应用的异型轧辊，过去很难进行磨削加工。个别厂曾用成形砂轮磨单圆弧的成形辊，每换一种尺寸就需一个规格的砂轮，并且无法磨创大尺寸以及任意曲线的轧辊本文给出了包络法磨削的原理及介绍了计算机数字控制的包络磨削法磨床。这对于解决高精度复杂型面轧辊的加工，提高钢管的产品质量有重要意义。

This article introduced the enveloping method, as well as the CNC grinding machine. Using computer technology, the complix and high precision contour of roll can be worked out by a single grinding wheel.
