Titanium Machining-FAQS

  • Corrosion resistant to seawater, aqua regia and chlorine
  • Can be alloyed with iron, aluminum, vanadium and molybdenum
  • Good ductility, high melting point, low thermal conductivity
  • Does not react with fleshy tissue and bones
  • Very active in liquid form
  • Not attacked by inorganic acids at room temperature

Any material has its advantages and disadvantages, in order to further improve the corrosion resistance, high temperature oxidation resistance, wear resistance and fretting resistance of titanium alloy parts.

Surface treatment of titanium parts after CNC machining is an effective way to further expand the use of titanium alloys.

The surface treatment process of titanium alloy covers almost all methods of metal surface treatment at present, including metal plating, electroless plating, thermal diffusion, anodizing, thermal spraying, low-pressure ion process, surface alloying of electrons and lasers, non-equilibrium magnetron Sputtering coating, ion nitriding, PVD coating, ion coating, nanotechnology, etc.

CNC technology has revolutionized the field of drilling by offering advanced solutions that enhance efficiency, accuracy, and versatility.

With CNC drilling, manufacturers can achieve precise hole placement, depths, and diameters, ensuring optimal component functionality.

The use of high-speed spindles and advanced tooling enables rapid material removal and minimizes cycle times.

Furthermore, CNC drilling machines can automate tool changes, reducing downtime and improving productivity.

These advancements have made CNC drilling an indispensable technique in industries such as electronics, metalworking, and construction.

There are many reasons for the defect that the oxide scale is not removed completely, and each process may be possible. There may be poor degreasing, or insufficient time for molten salt treatment, or failure of the pickling solution.When this defect occurs, various possible factors should be excluded one by one, and sandblasting process can be added to the pretreatment when necessary.

Shenzhen YIJIN Hardware has provided custom metal fabrication for customers in the medical industry for a long time.

It has processed various custom titanium parts, and is specially equipped with tools suitable for processing titanium alloys.

More than 60 machining centers can improve machining efficiency and shorten machining cycles.

The machining accuracy can reach 0.005mm, and the three-dimensional, micrometer and other precision testing instruments are complete, ensuring the qualified rate of shipment of titanium alloy products!

Grade 5 (Ti-6Al-4V) is the most common titanium alloy, offering excellent strength and reasonable machinability. Grade 23 (Ti-6Al-4V ELI – Extra Low Interstitials) is a higher purity version with reduced oxygen content, offering improved ductility and fracture toughness, making it preferred for critical medical implants.

Titanium offers superior biocompatibility, lighter weight, and better corrosion resistance compared to stainless steel. While more expensive, titanium’s lower modulus of elasticity reduces stress shielding in orthopedic implants, promoting better bone integration and long-term outcomes.

While possible in certain limited applications, machining titanium without coolant is generally not recommended. Proper cooling is essential to manage heat, extend tool life, maintain dimensional accuracy, and achieve good surface finish. We utilize high-pressure coolant systems specifically optimized for titanium machining.

We employ a comprehensive quality control system including material certification verification, in-process inspection, statistical process control, and final dimensional verification using advanced measurement equipment. All titanium parts undergo rigorous inspection to ensure they meet specified requirements.
Titanium components typically cost 3-5 times more than equivalent aluminum parts due to higher material costs, more complex machining requirements, increased tool wear, and longer cycle times. However, the superior performance and longer service life often justify this investment for critical applications.
