Workbench type power cutting machine

The invention discloses a workbench type power cutting machine. The workbench type power cutting machine comprises a base, a workbench and a cutting device. The workbench comprises a carrying plane. The cutting device comprises a cutting piece and a drive assembly. The cutting piece is provided with at least one part partially exposed out of the workbench to be in direct contact with an object to be cut. The part is an effective cutting part of the cutting piece. The effective cutting part is provided with at least one cutting face. The distance between the farthest end of the part, exposed out of the workbench, of the effective cutting part and the carrying plane is the effective cutting height of the cutting piece. During rotating, the cutting device is at least provided with a reference position enabling the cutting face to be perpendicular to the carrying plane, and the direction perpendicular to the carrying plane is the reference direction. The workbench type power cutting machine further comprises a dip angle adjusting mechanism through which the cutting device rotates out of the reference position and at least moves in the reference direction, and the rotating axis of the cutting device can move relative to the workbench. According to the workbench type power cutting machine, the object to be cut can be obliquely cut.
