The linear ball guide ways are widely used in numerical controlled systems, such as X-Y table, manufacturing facility or other devices. The titanium alloys would be the one of the candidates for rail material in sever environment, such as food processing industry, medical area or aerospace industry. The evaluation experiments are carried out to confirm the possibility of these titanium alloys for guide way system. This paper shows the results that the endurance properties of Ti-6Al-4V alloy with burnished treatment are more favorable compared to other type of titanium alloys.
