The invention belongs to the technical field of electromachining and provides high-speed rotation tool electrode electromachining equipment driven by a Tesla turbine. The high-speed rotation tool electrode electromachining equipment comprises an end cover, a shell, a driving disc, a rotary shaft, an electric-induced screw, an automatic end face adjusting sealing device, a high-speed bearing, a collet chuck, a key, a gasket, an elastic check ring and a tool electrode. The driving disc is connected with the rotary shaft through the key and provides driving force for high-speed rotation of the tool electrode. The electric-induced screw is fixed to the shell. Currents are transferred to a working electrode through working liquid in the shell and the rotary shaft. By means of the automatic adjusting sealing device, the effect that the device is reliably sealed when the rotary shaft rotates is guaranteed. By the adoption of the high-speed rotation tool electrode electromachining equipment, high-speed rotation of the tool electrode can be achieved, and reliable electric induction can be achieved during high-speed rotation. The high-speed rotation tool electrode electromachining equipment can be used in the electromachining fields such as electrochemical machining, electrosparking machining and electrochemical discharge machining.
