This kind of cutting machine is mainly to splitting the block foam into thin slices, the worktable adopts automatic digital control, and with suction device, increase the friction and adsorption between the platform and the sponge during the cutting process, which can make the sponge cutting more accurate. According to the thickness to be cut and the density of the foam, set the value through the touch screen, the table automatically reciprocates to cut the required size. The blade panel belt cutting angle can be adjusted from 0° to 5°. When cutting thick foam, in order to prevent cutting of the foam sliding, can be added to the pressure roller device, so as to make the cutting of the thickness of a more accurate.
