What are the advantages of CNC machining of radiator parts?

For friends who have been in contact with the radiator component industry, they often see or hear "CNC machining", but too much exposure does not necessarily mean that many people understand. In fact, many questions are still about CNC machining. What are the advantages? Let's take a closer look. CNC machining is an index-controlled machine tool machining, which is a method of using digital information to control the machining process. Traditional mechanical processing is done manually by machine tools. During processing, the mechanical cutter is shaken to cut metal, and the accuracy is measured with calipers and other tools. However, traditional artificial intelligence processing is far from being able to meet the needs of production development. Therefore, the emergence of CNC machining provides the possibility for the standardization, precision and efficiency of mechanical product processing. The CNC machining process in the radiator component industry also shines. The

How Do Cnc Swiss Machines Work

How Do Cnc Swiss Machines Work Save 0 What Is Swiss Machine –The full name of the walking CNC lathe, it can also be called the spindle box mobile CNC automatic lathe, the economical turning and milling compound machine tool or the slitting lathe. It belongs to precision machining equipment, which can complete compound  machining such as turning, milling, drilling, boring, tapping, and engraving at one time. It is mainly used for batch  machining of precision hardware and special-shaped shafts. This machine tool first originated in Germany and Switzerland. In the early stage, it was mainly used for precision machining of military equipment. With the continuous development and expansion of industrialization, due to the urgent needs of the market, it was gradually applied to the  machining of civilian products; the development of similar machine tools in Japan and South Korea Earlier than China, it was mainly used in the military industry in the early days. After the war, it was gradually

Spring Design Attention And Roll Forming Method

Spring Design Attention And Roll Forming Method The coiling characteristics and methods of springs are divided into cold coiling method and hot coiling method. Cold winding method: When the diameter of the spring wire is less than 8mm, the cold winding method is adopted. High-quality carbon spring steel wire is usually first cold drawn and then heat treated. After winding, it is generally not quenched, but only tempered at low temperature to eliminate the internal stress during winding. Hot-rolling method: Springs with larger diameter (>8mm) spring wire should use hot-rolling method. Hot rolled springs must be quenched and tempered at medium temperature. The Design Process Of Various Springs ·          Installation space: When designing a  compression spring , it is necessary to have a clear understanding of the space required for the installation of the spring, in order to effectively grasp the basic manufacturing conditions of the compression spring, including the outer diam

The Marten Properties Of Titanium

Low density and high specific strength

Metallic titanium has a density of 4.51 g / cm3, higher than aluminum and lower than steel, copper and nickel, but has the highest specific density of any metal.

Corrosion resistance

Titanium is a highly active metal with a low equilibrium potential and a high propensity for thermodynamic corrosion in the medium. However, titanium is actually very stable in many media. For example, titanium resists corrosion in the medium, including oxidation, neutral, and weak reducing properties. This is because the affinity between titanium and oxygen is large. In air or oxygen-containing media, a dense, strong and inert oxide film is formed on the surface of the titanium, protecting the titanium substrate from corrosion. Even if it wears mechanically, it will heal and regenerate immediately. This indicates that titanium is a metal with a strong tendency to passivate. Titanium oxide films below 315 ° C always maintain this property.

Surface treatment techniques such as oxidation, electroplating, plasma spraying, ion nitriding, ion implantation, and laser processing are being studied to improve the corrosion resistance of titanium. The titanium oxide film is for enhancing protection and obtaining desired corrosion resistance. Titanium-molybdenum, titanium-palladium, titanium-molybdenum-nickel and other corrosion-resistant titanium alloys are available for the production of metallic materials suitable for the production of sulfuric acid, hydrochloric acid, methylamine solutions, hot wet chlorine and hot chlorides. It is being developed.

A titanium-32-molybdenum alloy is used for the titanium casting. Titanium-0.3 molybdenum-0.8 nickel alloys are used in environments where crevice corrosion and pitting corrosion occur frequently. Titanium-0.2-palladium alloy was partially applied to titanium devices with good results.

  • Titanium casting
  • Good heat resistance
  • The new titanium alloy can be used for a long time above 600 ° C.

Cold resistance

Titanium alloys TA7 (Ti-5Al-2.5Sn), TC4 (Ti-6Al-4V), Ti-2.5Zr-1.5Mo and other low-temperature titanium alloys increase in strength as the temperature decreases, but their plasticity increases. Not very big. Maintains good ductility and toughness at -196-253 ° C and avoids low temperature brittleness. It is an ideal material for cryogenic containers and storage tanks.

Strong anti-dumping performance

Titanium metal is subject to mechanical and electrical vibrations and has the longest vibration damping time of its own compared to steel and copper metals. This characteristic of titanium can be used as a tuning fork, a vibrating element for a medical ultrasonic vibrator, and a diaphragm for an advanced speaker.

Tensile strength is close to its yield strength

This titanium property exhibits a high yield strength ratio (tensile strength / yield strength), indicating that the metallic titanium material has poor plastic deformation during the molding process. Since the ratio of the yield limit of titanium to the elastic modulus is large, the repulsive force of titanium during molding is large.

Good heat transfer performance

The thermal conductivity of metallic titanium is lower than that of carbon steel and copper,
However, due to the excellent corrosion resistance of titanium, the wall thickness can be significantly reduced and the heat exchange between the surface and the vapor is droplet condensation, which reduces the heat group. Since there is no scaling of the titanium surface, heat resistance is reduced and the heat transfer performance of titanium is greatly improved.

Low elastic modulus

The elastic modulus of titanium is 106.4 GPa at room temperature, which is 57% of that of steel.

Inhalation performance

Titanium is a highly chemically reactive metal that reacts with many elements and compounds at high temperatures. Inhalation of titanium mainly refers to the reaction with carbon, hydrogen, nitrogen and oxygen at high temperatures.
