Arden Engineering specializes in full-service titanium CNC machining services. Our superior capabilities allow us to work on special materials, like titanium, a common requirement for many projects. Used in many applications, our titanium CNC service can ensure quality outcomes that will drive success to your operations.
Why Use Titanium?
Titanium is among the most popular and valuable materials that many professionals, like architects and engineers, use. It's easy to work with and has many desirable material properties, such as an excellent strength-to-weight ratio.
Other benefits of titanium include:
- Exceptional resistance to corrosion
- Good machinability
- Maintain durability even when exposed to extreme temperatures
Titanium CNC Machining Capabilities
Although titanium has multiple benefits, its properties can still react negatively if the wrong manufacturing technique is used. However, CNC machining is almost always the best method to achieve accurate and affordable titanium parts.
Two of our CNC machining capabilities for titanium are CNC milling and Swiss screw machining since titanium can be cut, milled, and formed while retaining strength and structural integrity.
Common applications include:
- Medical implants and devices
- Cylindrical parts and components
- Aircraft engine parts and frames
Titanium Grades We Work With
Titanium is available in several machinable grades due to its increasing demand. Each has varying percentages of pure titanium and other alloying elements. Therefore, they have different mechanical properties, allowing you to choose the suitable grade for your projects.
- Grade 1 (commercially pure titanium): It contains low oxygen content and is known as the most ductile and softest titanium alloy on the list, so it has lower strength.
- Grade 2 (commercially pure titanium): It has a standard oxygen content and is more robust than Grade 1.
- Grade 3 (commercially pure titanium): It has medium oxygen content and is the least commercially used but possesses good mechanical properties.
- Grade 4 (commercially pure titanium): It has a high oxygen content and is the strongest of the four commercially pure grades.
- Grade 5 (Ti6Al4V): Contains 6% aluminum and 4% vanadium and is the most used titanium alloy.
- Grade 6 (Ti5Al-2.5Sn): Commonly used in aerospace applications, such as frames and jets.
- Grade 7 (Ti-0.15Pd): Similar to Grade 2 with small amounts of palladium, which enhances corrosion resistance.
- Grade 11 (Ti-0.15Pd): Similar to Grade 7 with lower tolerance to impurities.
- Grade 12 (Ti0.3Mo0.8Ni): Highly durable and contains 0.3% molybdenum and 0.8% nickel.
- Grade 23 (T6Al4V-ELI): ELI stands for Extra Low Interstitial. Similar to Grade 5 with higher purity.
Few Considerations When Machining Titanium
Titanium's unique characteristics require careful consideration to ensure its quality won't be compromised. These include:
- Heat buildup: Since titanium is more rigid than common machining materials, heat buildup may happen at the point of contact. High-pressure coolants ease the strain, and reducing the machine's RPM is advised.
- Galling: Pure titanium becomes gummy during machining, quickly sticking to the tool. It results in the galling and built-up edge. Using a high-pressure coolant ensures swift removal during these instances.
- Workholding: Titanium alloys are less rigid than other materials. They require a tighter grip during machining, so a rigid machine setup is essential.
