CNC cutting, refers to the control of machine tools or equipment for the workpiece instructions (or procedures), is given in digital form a new control. This directive is provided to the control device of the NC automatic cutting machine, the cutter can be cut automatically according to the given program. CNC cutting by the CNC system and mechanical structure of two parts. Compared with traditional manual and semi-automatic cutting, CNC cutting through CNC system that is the controller provides cutting technology, cutting technology and automatic control technology, effectively controlling and improving cutting quality and cutting efficiency. CNC cutting: CNC flame, plasma, laser and water jet cutting machine, according to the CNC cutting kit software to provide the optimized set of cutting process for full time, automatic, efficient, high-quality, highly utilized CNC cutting. CNC cutting represents the modern high-tech production, is the advanced optimization of nesting technology and computer numerical control techniques and cutting machinery combined products.
