Pipe bending beveling machine cutting is the previous process of welding, so the cutting quality directly affects whether the welding work can be carried out smoothly. Among them, groove cutting is one of cutting, also known as beveling. That is, the groove required for welding shall be made on the plate to be cut, so that the product can be welded thoroughly and firmly.

At present, China's cutting and welding enterprises generally use CNC cutting machine, edge planer, groove cutting robot, trolley cutting machine, or manual processing to complete the welding groove after secondary or even tertiary processing, resulting in the need to enlarge the groove welding allowance. Therefore, this kind of groove cutting not only has low cutting production efficiency, but also has serious material waste. NC groove cutting technology is to pre complete the groove setting of parts and the nesting and programming of parts with grooves on the computer through the NC groove programming nesting software, generate the NC cutting nesting file with groove cutting command, and then complete the groove and nesting cutting of whole plate parts at one time on the NC groove cutting machine, so as to effectively save steel, Effectively improve the quality and efficiency of groove cutting.
