CNC Machining Titanium Parts

Titanium materials are made from titanium ingots or titanium alloy metals through specific pressure processing techniques, resulting in materials with defined shapes, sizes, and properties, also known as titanium processed materials. The production of titanium materials primarily relies on pressure processing, which causes the processed objects (such as blanks and ingots) to undergo plastic deformation. Based on the processing temperature, titanium materials can be divided into two main categories: cold processing and hot processing. Depending on the processing techniques and the form of the final product, they can be broadly classified into various types such as plates, bars, pipes, forgings, and castings.

Titanium processed materials are widely used in high-end fields such as advanced chemicals, aerospace, medical, and marine engineering. Among them, with the advancement of technology and the expanding demand for applications, the need for titanium materials in the aerospace field has grown particularly significantly.

CNC Machining Titanium Material Parts

Titanium ores mainly consist of ilmenite and rutile. The two key advantages of titanium are its high specific strength and excellent corrosion resistance, which make it highly applicable in fields such as aerospace, defense, energy, chemical industry, metallurgy, construction, and transportation. The abundant titanium ore reserves provide a resource base for the wide application of titanium materials.

CNC Machining Titanium Material Properties

Low Density: The density of titanium metal is 4.51g/cm³, which is about 50% of copper and 77% of low carbon steel.

Corrosion Resistance: Titanium can form an oxide film in the air and is almost completely resistant to corrosion from seawater, earning it the nickname “marine metal.” Titanium has excellent corrosion resistance and is widely used in industries such as chlor-alkali, soda ash, vacuum salt production, petrochemicals, shipbuilding, seawater desalination, nuclear power plants, and thermal power desulfurization.

Temperature Performance: New titanium alloys can be used at temperatures of 600°C or higher temporarily while maintaining ductility and toughness. They are especially suitable for space applications at low temperatures between -196°C and -253°C. Therefore, titanium is known as the “space metal.” It is also widely used in aerospace, refrigeration, and other industries, and is biocompatible, free from metal allergies, which has earned it the title of “biometal.”

Superconductivity: Wires made from niobium-titanium alloys exhibit zero resistance below the critical temperature and can conduct through any power equipment, demonstrating other superconducting properties. Currently, the consumption of titanium materials in China is mainly in the chemical industry, aerospace, and sports and leisure fields.

CNC Machining Titanium FAQs

Due to the characteristics of titanium materials, such as high strength, high toughness, and low thermal conductivity, commonly used tools include carbide tools, which have high hardness and good wear resistance, allowing them to withstand high cutting temperatures and pressures. Coated tools are also commonly used. By applying one or more layers of high-hardness, wear-resistant coatings, such as titanium nitride (TiN) or titanium aluminum nitride (TiAlN), to the tool surface, the hardness, wear resistance, and lubricity of the tools are improved, which reduces cutting force and temperature, and extends tool life.

The thermal conductivity of most titanium alloys is very low, only about 1/3 or 1/4 that of steel, and 1/16 that of aluminum. Due to the extremely low thermal conductivity of titanium alloys, the heat generated during the cutting process cannot be quickly transferred or dissipated, nor can it be effectively carried away by the chips. As a result, a large amount of cutting heat accumulates in the cutting area, significantly raising the temperature at the contact point between the tool and the workpiece, which can reach over 1000°C. This leads to rapid tool wear, chipping, and cracking, greatly shortening tool life.

The high temperatures generated during cutting also damage the surface integrity of titanium alloy parts, leading to a decrease in the geometric accuracy of the parts and causing work hardening on the surface, which severely reduces their fatigue strength.

Grade 5 (Ti-6Al-4V) and Grade 23 (Ti-6Al-4V ELI) are generally considered the best titanium alloy grades because of their excellent performance in strength, corrosion resistance, toughness, and biocompatibility, making them suitable for various high-end applications.
