What are the differences between Forging and CNC Machining?
Aluminum alloy forging is to use the plasticity of the material to produce plastic deformation with the help of external force to obtain forgings with the required shape, size and certain structural properties. Advantages: Forgings are dense and uniform in structure, and their performance is higher than die-casting, cutting and welding parts. Disadvantages: requires a large deformation force. What everyone needs to pay attention to is the forging technology and classification, which are mainly divided into warm forging technology and cold forging technology.
Numerical control machining refers to a process method for processing parts on a CNC machine tool. The process regulations of CNC machine tool processing and traditional machine tool processing are generally consistent, but significant changes have also taken place. A machining method that uses digital information to control the displacement of parts and tools. It is an effective way to solve the problems of variable parts, small batches, complex shapes, and high precision, and to realize efficient and automated processing.
What is forging？
Forging is a processing method that uses forging machinery to apply pressure to metal blanks to produce plastic deformation to obtain forgings with certain mechanical properties, certain shapes and sizes. Forging (forging and stamping) is one of the two major components. Forging can eliminate defects such as loose as-cast during the smelting process and optimize the microstructure. At the same time, due to the preservation of the complete metal streamline, the mechanical properties of forgings are generally better than those of castings of the same material. For the important parts of related machinery with high load and severe working conditions, in addition to simpler shapes that can be rolled, profiles or welded parts, forgings are mostly used.
Advantages of forging:
- It can produce parts with complex shapes, especially blanks with complex cavities.
- Wide adaptability, metal materials commonly used in industry can be cast, from a few grams to hundreds of tons.
- Wide sources of raw materials, low prices, such as scrap steel, scrap, chips, etc.
- The shape and size of the casting is very close to that of the part, which reduces the amount of cutting and belongs to non-cutting processing
- Widely used, 40%~70% of agricultural machinery and 70%~80% of the weight of machine tools are castings

What are the material requirements for forging?
Forging materials are mainly carbon steel and alloy steel with various compositions,
followed by aluminum, magnesium, copper, titanium, etc. and their alloys. The original
state of the material includes bar stock, ingot, metal powder and liquid metal. The ratio
of the cross-sectional area of the metal before deformation to the cross-sectional area
after deformation is called the forging ratio. Correct selection of forging ratio,
reasonable heating temperature and holding time, reasonable initial forging temperature and
final forging temperature, reasonable deformation amount and deformation speed have a great
relationship with improving product quality and reducing cost.
Features of die forging:
- High productivity.
- The shape of the forging is more complicated and the dimensional accuracy is high.
- The machining allowance is small and the material utilization rate is high.
- However, the streamline distribution is more reasonable, and the service life of the parts is improved.
- The production process is easy to operate and the labor intensity is low.
- After mass production, its cost is low.
