In order to solve some problems relating to airflow caused by rotating chuck of a CNC lathe or turning center, the airflow in a closed space assumed a machining space is observed by means of the tuft and tracer methods. Flow visualizations are carried out when chuck rotating speeds are 2000,3000,and 4000(min)^<-1>, and also the rotating directions of chuck are clockwise and counterclockwise. The investigation shows some characteristic airflow patterns in the close space; (1) After a radial airflow blowing from the rotating chuck strikes the panel near the headstock side, the airflow goes in the direction of tailstock through the surface of panel. (2) Vortex-like flow is occurred near the tailstock panel side. (3) The region of weak airflow exists on the slant and bottom panels.
