CNC (computer numerical control), also called Numerical control. It refers to the automatic control of machining tools and 3D printers through computers.

The materials for making stamping dies include steel, hard alloy, steel-bonded hard alloy, zinc-based alloy, low melting point alloy, aluminum bronze, polymer material and so on. Most of the materials for manufacturing stamping dies are mainly steel.

Under normal circumstances, the color of the finished precision castings is silver-white or silver-gray, but after a period of use, some castings will appear black, and the whole or part of the castings are processed products and designs. If the concept does not match, it will be deformed. What are the reasons and solutions for blackening and deformation?

Die forging is a method of forming on a forging die developed on the basis of free forging and die forging in order to solve the problems of low productivity and poor precision of free forging, and to achieve the needs of large-scale and specialized production of forgings. Die forging is the abbreviation of model forging. The forging die (forging die) is generally composed of an upper die and a lower die. The upper and lower dies of the forging die are respectively fixed on the hammer head and the die pad. or die groove), the shape and size of the cavity of the groove is the same as the shape and size of the forging. During die forging, the blank is placed on the lower die, and the upper die moves down with the hammer (or slider) to close the die (one or more times) to hit the blank. Under the action, plastic deformation is generated and the groove is filled, and finally a forging with the same shape as the groove is obtained.

Magnesium is a young metal that was developed in the 20th century; its chemical activity is strong, and its affinity with oxygen is large. It is often used as a reducing agent to replace metals such as titanium, zirconium, uranium, and beryllium. Magnesium metal is non-magnetic and has good heat dissipation. The structural properties of magnesium are similar to those of aluminum, so it has various uses as a light metal, and can be used as an alloy material for aircraft and missiles. However, magnesium is flammable at the ignition point of gasoline, which limits its application.
