CNC cutting machine manufacturers tell you how to prevent material bending?

　　 The materials processed by the CNC cutting machine in use often produce some phenomena that affect the use, so that the quality of the workpiece is not conducive to the later cutting work, and it is necessary to make it clear that it is necessary to avoid affecting the processing during the cutting process. Therefore, we must take precautions before cutting. Next, the CNC cutting machine manufacturer will give you a specific introduction.

　　(1) Try to use vacuum melting, refining or electroslag remelting steel;

　　(2) Strict inspection The chemical composition, metallographic structure and flaw detection of raw materials shall not use unqualified raw materials, coarse-grained steel and steel with excessive harmful impurities;

　　(3) Avoid using materials with poor hardenability and easy deformation;

　　(4) Blank forging should be reasonable, upsetting compliance, stretchability, forging ratio, forging length, and matching with raw materials, that is, the forging ratio should be a code with a diameter ratio of 2-3;

　　(5) Choose the ideal cooling rate and cooling medium;

　　(6) By vacuum heating, protective atmosphere heating, complete deoxidation salt bath heating, stage quenching, isothermal quenching, etc. Improve the heat treatment process;

　　(7) The CNC cutting machine manufacturer mentioned that the chemically treated tool steel should be subjected to diffusion annealing, spheroidizing annealing, quenching and tempering to fully refine the original structure;

　　(8) Long-term tempering can improve the fracture toughness of the mold;

　　(9) Fully tempering to obtain stable structure and performance;

　　(10) more Secondary tempering and retained austenite are sufficient to eliminate new stress;

　　(11) Quenched steel should be tempered in time to eliminate quenching internal stress and reduce brittleness as much as possible;

　　(12 ) Tempered brittle die steel should be cooled (water-cooled or oil-cooled) after high-temperature tempering to eliminate secondary temper brittleness. The intersecting wire cutting machine has built-in advanced PID algorithm, fast response speed, strong adaptability, simple debugging; 16-level speed control, simple PLC realizes timing, constant speed, orientation and other multi-functional logic control, and a variety of flexible control methods can meet various requirements. The requirements of a complex working condition. The mechatronics cutting machine of the CNC cutting machine is called the CNC cutting machine.

　　 The above is the specific content of preventing material bending introduced by CNC cutting machine manufacturers. In order to reduce and prevent deformation and cracking, according to the needs of material selection for hot-processed wire cutting molds, from the finished product Enough attention and attention should be paid to all aspects of heat treatment at the beginning, select materials with less deformation, and adopt the correct heat treatment process.
