The working principle of the wood cutting device capable of polishing is as follows: when the wood board is cut, the driving piece 300 is powered on and rotates at a high speed, the rotating driving piece 300 drives the cutter 400 to rotate quickly, only the sawtooth part of the cutter 400 is aligned to the part, to be cut, of the wood board, the wood board is pushed to the cutter 400, therefore, in the process of high-speed rotation of the cutter 400, the sawtooth part of the cutter 400 can cut the wood board, the wood board and the butting part of the sawtooth part can be broken by shearing force, and the wood board can be cut. After the wood board cutting operation is completed, the servo motor 221 is started, the rotor of the servo motor 221 rotates and drives the screw rod 222 to rotate, so that the receiving piece 223 rotatably connected with the screw rod 222 moves along the axial direction of the screw rod 222, and accordingly, the driving piece 300 and the cutter 400 are driven to move along the vertical direction in the moving process of the receiving piece 223, so that the position of the cutter 400 can be adjusted.

The vertical adjustment unit 220 is used to adjust a vertical distance from the saw-tooth portion of the cutter 400 to the board, and may also be understood as being used to adjust a horizontal height of the polishing disk 500 so that the polishing disk 500 approaches and polishes the board section. Specifically, after the servo motor 221 is powered on, the rotor of the servo motor 221 drives the screw rod 222 to rotate at a high speed, and since the screw rod 222 is rotatably connected with the receiving part 223, when the screw rod 222 rotates, the receiving part 223 moves along the axial direction, i.e., the vertical direction, of the screw rod 222 to change the horizontal height of the driving part 300, so as to adjust the horizontal height of the cutter 400, and realize the switching between the abutment of the sawtooth part of the cutter 400 and the wood board and the abutment of the polishing disc 500 and the wood board cutting surface.
