The present invention relates to an angle number variable type turret lathe. In particular, the turret lathe can be changed from a turret having 12 angles after being divided in the equal angle of 30 to a turret having 24 angles after being divided in the equal angle of 15, and vice versa. If the 12 angles mode or the 24 angles mode is chosen when the number of angles is changed, the present invention is automatically changed to a rotary angle corresponding to each mode.;COPYRIGHT KIPO 2019
