摘要
全面比较了用Ａｌ２Ｏ３和ＣＢＮ磨削Ｋ４１７铸造高温合金时的磨削效果，指出：Ａｌ２Ｏ３不适于高效磨削Ｋ４１７之类的航空难加工材料，而ＣＢＮ是实现该材料高效深切磨削的有效工具。通过大量实验，验证了断续ＣＢＮ砂轮缓进给磨削Ｋ４１７时的技术优势，解决了树脂结合剂应用于断续磨削时所遇到的新问题。
The effects of creep grinding of nickel base cast superalloy K417 with Al 2O 3 and CBN wheels have been compared thoroughly. It is pointed out that Al 2O 3 is not suitable for highly efficient grinding of difficult to machine material used in aeronautics such as K417, and that CBN is an effective tool for creep feed grinding of those materials with high efficiency. By a large amount of experiments, it has been verified that intermittent CBN wheel is superior in creep feed grinding of K417. The new problems encountered when applying resin bonded wheels in intermittent grinding have been comparatively perfectly solved. Comprehensive effect analysis in the end shows that the technical art has a prospective future of application and extreme value to be spread.
