摘　　要：磨削强化技术是一种集磨削加工与表面淬火于一体的新技术,可对钢件表层进行强化处理。针对矿山机械中的常用材料40Cr钢进行了磨削强化试验,通过改变进给速度与磨削深度研究了强化层深度的变化规律,并进一步阐述了磨削强化技术对于40Cr钢的可行性与必要性。The grind - hardening is a new technology that integrates grinding and surface hardening and enhances material capability of workpiece surface. The grind - hardening experiments of 40Cr steel frequently used in mining machine are adopted, and the length of hardened layer is investigated according to the various feeding speeds and cut depths. At last, the feasibility and essentiality of the application of this technology for 40Cr steel are pointed out.
