Experimental Study on the Hardened Surface Layer of Grinding SKD-11 Hardened Steel

Abstract

The grind-hardening process integrates heat treatment processing into the production line, reduces the number of producing procedures, shortens machining period and lowers the cost. Meanwhile, grind-hardening machining doesn’t use cutting fluid. So the grind-hardening process is a green manufacturing method with an extending application in future. Grinding hardening is an effective method in machining SKD-11 hardened steel due to its good quenched property. In this paper, the grind-hardening characteristics of SKD-11 hardened steel are discussed, and the impacts on the hardened surface layer varying with the grinding parameters are also studied. Optimization of grinding parameters of SKD-11 hardened steel is conducted based on the study.
