最近开发了一种陶瓷化CBN砂轮，能够以40000 SFPM（200 M/s）的速度运行。为了在如此高的速度下研磨，使用碳纤维增强塑料开发了一种特殊的芯。这种专门设计的型芯具有足够高的强度和足够低的膨胀率，可以在研磨过程中产生的高离心力下工作。这种陶瓷化CBN车轮已经在40000英尺/分（200米/秒）的超高速下进行了测试。这些测试证实，更高的速度将使磨削效率和砂轮寿命持续大幅提高。

A VITRIFIED CBN GRINDING WHEEL WAS RECENTLY DEVELOPED CAPABLE OF OPERATING AT SPEEDS OF 40,000SFPM (200 M/SEC). IN ORDER TO GRIND AT SUCH HIGH SPEEDS A SPECIAL CORE WAS DEVELOPED USING A CARBON FIBER REINFORCED PLASTIC. THIS SPECIFICALLY DESIGNED CORE HAS HIGH ENOUGH STRENGTH AND LOW ENOUGH EXPANSION TO OPERATE AT THE HIGH CENTRIFUGAL FORCES GENERATED DURING GRINDING. THIS VITRIFIED CBN WHEEL HAS BEEN TESTED AT SUPER HIGH SPEEDS OF 40,000SFPM (200 M/SEC). THESE TESTS CONFIRMED THAT THE HIGHER SPEEDS WILL GIVE CONTINUAL AND BIG IMPROVEMENTS IN GRINDING EFFICIENCY AND WHEEL LIFE.
