单道次超硬磨料镗孔精加工工艺作为精密加工零件内径的一种有效方法正在迅速普及。通过这一过程，在高生产率下，操作员参与最少的情况下，可以始终实现非常接近的公差。本文讨论了工艺基础以及所需的超硬磨具。

THE SINGLE PASS, SUPERABRASIVE BORE FINISHING PROCESS IS ONE THAT IS QUICKLY GAINING POPULARITY AS AN EFFECTIVE MEANS OF PRECISION FINISHING THE INSIDE DIAMETER OF A PART. WITH THIS PROCESS, VERY CLOSE TOLERANCES CAN BE CONSISTENTLY ACHIEVED AT HIGH PRODUCTION RATES WITH MINIMAL OPERATOR INVOLVEMENT. THIS PAPER DISCUSSES THE PROCESS BASICS AS WELL AS THE REQUIRED SUPERABRASIVE TOOLING.
