The invention discloses a linked-integrated cutting machine. The linked-integrated cutting machine comprises an electric box, a motor, a transmission belt, a loading plate, a pneumatic rod, a location cylinder, a rack, a fence, a workbench, a cutting wheel, a cutting frame, a slide rail, a chip removal pipeline, a linkage frame, a moving guide rail, a slide block, a loading frame and a loading cylinder. According to the linked-integrated cutting machine, five groups of machine tools can be arranged on the linkage frame simultaneously, and one straight line is formed by five linked cutting machines; the linked-integrated cutting machine is composed of five same machine tools, the first machine tool is in a fixed state, and the second machine tool, the third machine tool, the fourth machine tool and the fifth machine tool are capable of moving forwards and backwards; the needed cutting length can be adjusted by adjusting the positions of racks of the machine tools on the moving guide rail, so that a material is cut into four sections with a specified length; then the material is conveyed onto the workbench along the loading plate through the working of the loading cylinder, and discharged through a discharge port after being cut, so that automatic loading and automatic unloading can be realized, the continuous working is realized, and the working efficiency is greatly increased.
