Titanium is prized for its extraordinary strength-to-weight ratio and biocompatibility but is notoriously difficult to machine due to poor thermal conductivity. Jucheng Precision excels where others struggle. Utilizing our 25 sets of 5-axis Haas/Mazak CNC machines, we implement specialized cutting strategies to manage heat and prevent work hardening. Our facility is ISO 13485 certified, making us a trusted partner for manufacturing critical medical implants and surgical tools. Whether for aerospace turbine blades or lightweight automotive valves, we deliver titanium parts with tight tolerances and superior surface integrity.
The "workhorse" of Commercially Pure (CP) titanium. Grade 2 offers an outstanding balance of moderate strength and excellent ductility. Its superior corrosion resistance in highly oxidizing environments makes it the industry standard for chemical processing equipment, marine hardware, and heat exchangers where weldability is a primary requirement.
The most widely used titanium alloy globally. Grade 5 offers an incredible strength-to-weight ratio and high heat resistance. It is significantly stronger than pure titanium while maintaining good toughness. It is the premier choice for high-performance aerospace structures, turbine engine components, and automotive racing parts.
The high-purity, medical-grade version of Ti-6Al-4V. "ELI" stands for Extra Low Interstitial, providing superior fracture toughness and biocompatibility compared to Grade 5. It is the gold standard for permanent medical implants, spinal screws, and dental fixtures, ensuring long-term reliability and safety within the human body.
| Grade | Common Name | Key Characteristics | Typical Applications |
|---|---|---|---|
| Grade 2 | Commercially Pure (CP) | Excellent corrosion resistance, good formability, lower strength. Biocompatible. | Chemical processing, heat exchangers, medical casing, marine parts. |
| Grade 5 (Ti-6Al-4V) | The “Workhorse” Alloy | Most common alloy. High strength, heat treatable, lightweight. Difficult to machine. | Aerospace structures, turbine components, automotive engine parts, sports equipment. |
| Grade 23 (Ti-6Al-4V ELI) | Medical Grade | “Extra Low Interstitial” version of Grade 5. Higher purity, better fracture toughness. | Medical implants, surgical staples, orthopedic pins. |
| Grade 19 / Beta C | Beta Alloy | Heat treatable to very high strength. Excellent corrosion resistance. | High-strength springs, fasteners, deep-sea tubulars. |
| Capability | Technical Description | Jucheng Advantage |
|---|---|---|
| High-Pressure Coolant (HPC) | Utilization of 1000+ PSI coolant systems to blast chips away and force heat removal from the cutting zone. | Crucial for Titanium to prevent heat buildup, tool failure, and fire hazards. |
| 5-Axis Contouring | Simultaneous 5-axis machining for complex aerospace airfoils and medical implants with organic shapes. | Allows for shorter cutting tools, reducing vibration and improving surface finish on tough materials. |
| Swiss Turning | Precision turning of small diameter, long titanium parts like bone screws and dental implants. | ISO 13485 compliant processes ensure medical-grade precision and surface cleanliness. |
| EDM & Wire Cutting | Electrical Discharge Machining for creating intricate features in titanium without mechanical stress. | Ideal for internal splines or deep pockets in hardened titanium components. |
Heat Management:
Titanium does not conduct heat well; the heat concentrates at the cutting edge rather than dissipating into the chip. We use aggressive coolant strategies and lower cutting speeds to protect the tool and the part.
Tooling Selection:
We use specialized carbide tools with high relief angles and sharp cutting edges. Coated tools (like TiAlN) are used to provide heat resistance. Tools are replaced frequently to ensure sharpness, as dull tools cause work hardening.
Vibration Damping:
Titanium has a lower modulus of elasticity (it’s “springy”), causing chatter. We use rigid setups, short tool overhangs, and vibration-damping tool holders to maintain tight tolerances.
Safety Protocols:
Titanium chips can be flammable. Our facility is equipped with Class D fire suppression systems and strict chip management protocols to ensure safe manufacturing.
Medical Implants (ISO 13485)
Key Parts: Hip joints, bone plates, screws, dental posts.
Why Titanium: It is completely biocompatible (non-toxic to the body) and creates an osseointegration bond with bone.
