【摘要】 通过用陶瓷结合剂CBN砂轮对45淬硬钢工件进行磨削试验,分析了砂轮进给速度对砂轮磨损的影响。结果表明,当砂轮线速度为60m/s、砂轮进给速度为30～40μm/s时,国产陶瓷结合剂CBN砂轮在磨削过程中的磨损缓慢且均匀,同时可获得较高的磨削效率。更多还原

【Abstract】 Grinding experiments for 45 hardened steel workpiece were carried out with CBN(cubic boron nitride) wheel of vitrified bond. The effect of feeding speed on wear of CBN wheel has been studied by experiments. It is found,in an appropriate sand wheel feeding speed of 30～40 μm/s and linear speed of 60 m/s,very slow wear and high grinding efficiency of domestic ceramic bonded CBN wheel can be obtained.更多还原
