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。通过该工艺，在高生产率和最少操作员参与的情况下，可以始终实现非常接近的公差。本文讨论了涉及的超硬磨具，并提出了获得最大效益的方法。

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 THE PROCESS, VERY CLOSE TOLERANCES CAN BE CONSISTENTLY ACHIEVED AT HIGH-PRODUCTION RATES AND WITH MINIMUM OPERATOR INVOLVEMENT. THIS PAPER DISCUSSES THE SUPERABRASIVE TOOLING INVOLVED AND ALSO SUGGESTS WAYS IN WHICH MAXIMUM BENEFITS CAN BE OBTAINED.
