The process of spinning tube of Ti1300 titanium alloy was investigated. The temperature on hot spinning was 800 to 900℃. The roller feedin ratio was varied, and it is 0. 5 to 0. 8mm/ r in first spinning and it is 1. 2 to 2． 0 mm/ r in end spinning. The limit thinning ratio was about 85%, and each thinning ratio was 45%. It could be realized large thinning ratio with spinning process, but the cumulative thinning ratio was not too large.
