Abstract: A cutting device includes a base, an operation bench, and a cutting mechanism. The base includes a fluid cavity for containing a fluid. The operation bench is disposed on the base. The cutting mechanism includes a driving member and a cutting member. The driving member drives the cutting member to rotate. The cutting member at least partially protrudes from and passes through the operation bench. The cutting device includes a fluid control mechanism including a radial flow guiding member. The radial flow guiding member is disposed in the fluid cavity and includes at least a flow guiding surface disposed around a periphery of the cutting member. The fluid is capable of flowing along a surface of the flow guiding surface and the flow guiding surface is inclined or curved with respect to a bottom wall of the fluid cavity.
