This machine is the production equipment with high working efficiency, ready for self propelled operation as well as steady running. Suitable for high-volume centralized production, flexible to use in every place of workshop.A small investment, no limit working length and high working flexibility. During processing, the machine automatically feeds along the edge of plate with high feeding speed and high efficiency. Without any change of plate shape and plate metallography. At the same time, an operator can take care of several devices, the working condition is simple. Suitable for the cutting of ordinary carbon steel, medium carbon steel, stainless steel, aluminum alloy and other materials CHP-12 can bevel the 12mm width of the slope in a single pass (when the common carbon steel plate is the 400MP) CHP-28 can bevel the 28mm width of the slope in a single pass (when the common carbon steel plate is 400MP)
