Centerless grinding is a widely used manufacturing process in the mass production of precision parts. However, its productivity and precision is largely determined by the grinder set-up conditions, process stability and workpiece surface integrity. Grinding titanium alloys encounters difficulties due to its low thermal conductivity, high shear strength and extreme chemical reactivity. Therefore, the grindability of titanium alloy should be improved in order to increase the productivity for the sake of workpiece quality. In this paper, centerless grinding process was introduced initially and the research of impact factors on centerless grinding performance was reviewed. The problems occurred in the centerless grinding of titanium alloy were studied and optimum guidelines were proposed.
