The relationships between drill speed, whirl, squeeze effect and fluid force drill suffered is got by using cutting fluid Reynolds equation. Principle of deep-hole drilling drill whirl is studied, pointing out the promotion of positive precession cutting fluid component is drill whirl’s reason. Simulated and studied of drill whirl round shape at different times, suggesting that only when BTA drill suffered by the fluid force, stable motion can be obtained. Analysis of the anti-precession of drill, and the squeeze film damper work principle is revealed. Comparative studied the movement of the drill by using MATLAB software simulation before and after adding squeeze film damper.
