金属陶瓷刀具在硬质合金刀具市场上的份额越来越大。因此，高效加工这些难磨材料变得越来越重要。本文包含了一些尚未发表的关于这一主题的实验室结果。在多种切削条件下，使用不同规格的砂轮磨削各种金属陶瓷材料。

CERMET CUTTING TOOLS ARE GAINING AN EVEN LARGER SHARE OF THE HARDMETAL CUTTING TOOL MARKET. THEREFORE, THE EFFICIENT MACHINING OF THESE DIFFICULT-TO-GRIND MATERIALS IS BECOMING EVER MORE IMPORTANT. THIS PAPER CONTAINS SOME AS YET UNPUBLISHED LABORATORY RESULTS ON THIS SUBJECT. TESTS WERE RUN USING DIFFERENT WHEEL SPECIFICATIONS FOR GRINDING VARIOUS CERMET MATERIALS UNDER NUMEROUS CUTTING CONDITIONS.
