Grinding Titanium Alloy with Brazed Monolayer CBN Wheels

This paper deals with an investigation of the grindability of Titanium alloy Ti–6Al–4V with brazed monolayer CBN grinding wheels, and systematically studies the effect of process parameters on specific energy and grinding temperature. In the investigation, a groove is machined with a brazed monolayer CBN grinding wheel, and the dimension accuracy of groove has been proved to meet the design requirements. There is no microcrack in surface layer of the groove, and the depth of work-hardening is less than 40 μm, which indicates that the grinding affected zone is small. The results show that brazed monolayer CBN grinding wheels have excellent performance during grinding titanium alloy.
