在缓进给磨削时烧伤机理分析的基础上，提出了高压射流冲击强化磨削弧区换热的创新构想，并通过缓进给断续磨削时施加侧向射流冲击弧区的磨削实验研究其换热效果。实验结果表明，射流冲击强化换热技术确是提高弧区换热效率的有效方法，且射流速度越高，换热效果越好。该研究将在解决难加工材料磨削烧伤领域具有广阔的应用前景 Based on the analysis of the mechanism of burn-in burn-in, a new concept of heat transfer in high-pressure jet-blasting arc is put forward and the grinding of the lateral jet impact arc zone Experimental study of its heat transfer effect. The experimental results show that jet impact enhanced heat transfer technology is indeed an effective way to improve the heat transfer efficiency in the arc zone. The higher the jet velocity, the better the heat transfer effect. The research will have broad application prospects in the field of solving the problem of hard-burned material grinding burns
