一、问题的提出目前,在磨削加工中已开始使用人造金刚石和立方体氮化硼磨料。这两种超级磨料的硬度极高,可以用来磨削各种硬度的零件,而表现出其优越的磨削性能。虽然如此,但是这两种磨料制成的砂轮,由于磨粒硬,修整和修形都是很困难的,另一方面,这两种磨料都是用人工合成法制成,生产成本高,价格昂贵,据说在国外,立方体氮化硼磨料1立方时要400美元,人造金刚石要稍高一些,而普通刚玉磨
First, the issue raised At present, in the grinding process has begun to use synthetic diamond and cubic boron nitride abrasive. These two super abrasives are extremely hard and can be used to grind parts of various hardness to show their superior grinding performance. Nonetheless, the grinding wheels made of these two kinds of abrasives are difficult due to the hardness of the abrasive grains, and the dressing and the repair are very difficult. On the other hand, these two kinds of abrasives are all made by artificial synthesis, which has high production cost and high price , It is said that in foreign countries, the cubic boron nitride abrasive to 1 cubic 400 dollars, artificial diamond to be slightly higher, and ordinary corundum grinding
