チタン

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.

Titanium Machining Capabilities

能力 技術的説明 Juchengの強み
高圧クーラント(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.
スイス型旋盤加工 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・ワイヤカット Electrical Discharge Machining for creating intricate features in titanium without mechanical stress. Ideal for internal splines or deep pockets in hardened titanium components.

Fabrication Guidelines for Titanium

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.

工具の選定:
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.

Primary Application Industries
