Grinding Technique

Grind-hardening was done on Steel AISI 1066 with a conventional surface grinder and a corundum grinding wheel, and research was conducted to probe into structures and properties of the hardened layer under varied depth of cut and cooling conditions. Results show that the hardened layer do not change noticeably in their martensitic structures and micro-hardness, which is ranged between 810870HV; But when the depth of cut increased or the dry grinding technique is adopted, the concentration of martensites and carbonides becomes lower, while the amount of residual austenites increases, and the completely hardened zone gets thicker. This conclusion serves as an experimental basis for the active control of properties of the grind-hardened layer of Steel AISI 1066.

Arc Shape

On the basis of the cylindrical plunge grinding and intermittent axial feed grinding experiment, the grind-hardened layer structure and its property of the loader clevis pin were studied. The result shows that there are some arc shape medium/high-temperature tempered zones and some annular unhardened zone in external circumference surface, which is result of temperature gradient, induced grinding heat when circumferential feed and axial grinding heat conduction. The microstructure of hardened zone is mixture martensite, and the microstructure of tempered zone is tempered martensite and troostite. Different structure zone has same microhardness distribution regulation, but the microhardness of hardened zone can reach 640HV0.5. The loader clevis pin processed by grind-hardening meets the property request for working.

Grind Hardening

The grind-hardening technology utilizes the grinding heat to harden the surface of the workpiece. The friction and wear performance of the grind-hardened layer is one of the important parameters. In this paper, the friction and wear performance of the grind-hardened layer was studied by the friction and wear experiment. The wear rate and the friction coefficient of the grind-hardened steel were studied by comparing with conventional hardened steel and non-hardened steel. The surface worn morphology and the collected wear debris of the grind-hardened steel were observed during the experiment. The wear mechanism of the grind-hardened steel was analyzed under different friction conditions.
