Immersion tank and cutting equipment

The embodiment of the utility model provides a liquid immersion tank and cutting equipment, and the liquid immersion tank comprises a tank body which is provided with a liquid storage cavity used for containing cutting liquid; the inner plate is arranged in the liquid storage cavity and defines a containing cavity with the volume smaller than that of the liquid storage cavity; the inner plate is further provided with a liquid passing opening enabling the liquid storage cavity to be communicated with the containing cavity. The ultrasonic vibrator is arranged on the outer side of the bottom wall of the tank body; the vibration output end of the ultrasonic vibrator makes contact with the groove body and is used for applying ultrasonic vibration to the groove body and transmitting the ultrasonic vibration to the cutting fluid. According to the immersion tank and the cutting equipment provided by the embodiment of the invention, the heat dissipation effect in the cutting process can be improved, and the cutting qu
