Cutting device

The invention discloses a cutting device. An X-axis slide rail and a Y-axis slide rail are horizontally arranged on the upper surface of a base and are perpendicular to each other; a work surface is cooperatively guided by the X-axis slide rail and the Y-axis slide rail to horizontally move; the work surface is used for clamping a workpiece and positioning the workpiece; a cutting machine frame isguided by a Z-axis slide rail to slide vertically; a cutter is arranged on the cutting machine frame; the cutter is driven by the cutting machine frame to move vertically; a cutting motor is arrangedon the cutting machine frame and used for driving the cutter to rotate; during cutting, the workpiece is clamped and fixed to the work surface, the work surface is moved through the X-axis slide railand the Y-axis slide rail, adjusted to a proper position and positioned; and then the cutting machine frame is moved vertically, the cutter is driven to move downwards and to approach the to-be-cut workpiece, and cutting is co
