摘　　要：为进一步提升超薄树脂切割砂轮的自锐性能和排屑容屑能力,在切割砂轮中加入水溶性造孔剂NaCl,研究其含量对超薄树脂切割砂轮的微观形貌、力学性能及切割性能的影响。结果表明:当造孔剂添加体积分数为10%时,砂轮中的孔隙均匀适中,其切割效率最高,进给速度最高可达20 mm/s。但加入造孔剂会对砂轮的抗折性能和切割寿命产生一定影响,造孔剂含量越高,抗折性能越低,切割寿命越短。In order to further improve the self sharpening performance,the chip removal and the chip holding capacity of the ultra-thin resin cutting grinding wheel,the water-soluble pore-forming agent NaCl was added into the cutting grinding wheel,and the effects of its content on the micro morphology,the mechanical property and the cutting prop-erty of the ultra-thin resin cutting grinding wheel were studied.The results show that when the volume fraction of pore-forming agent is 10%,the pores in the grinding wheel are uniform and moderate,the cutting efficiency is the highest and the maximum feed speed can reach 20 mm/s.However,the addition of pore-forming agent will have a certain impact on the flexural performance and the cutting life of the grinding wheel.The higher the content of pore-forming agent,the lower the flexural performance and the shorter the cutting life.
