Titanium CNC Machining

Resolute Precision Manufacturing provides Titanium CNC Machining for precision components in Grade 2 (commercially pure titanium) and Grade 5 (Ti-6Al-4V) for aerospace, medical device, and high-performance industrial applications. Titanium combines an exceptional strength-to-weight ratio, corrosion resistance, and biocompatibility, making it suitable for demanding applications where aluminum may not provide enough strength and steel adds unnecessary weight.Our experienced machinists understand the specific requirements of titanium machining and produce Titanium Machined Parts for prototype, short-run, and production applications.

Titanium Machining -- The Process Requirements

Titanium is significantly more challenging to machine than aluminum or steel. Incorrect machining can result in accelerated tool wear, surface damage, heat buildup, and dimensional inaccuracy. Titanium has roughly one-sixth the thermal conductivity of steel, causing cutting heat to concentrate around the tool rather than being quickly dispersed through the chip or workpiece.

Resolute Precision addresses these challenges with flood coolant, sharp carbide tooling with geometries appropriate for titanium, and controlled cutting parameters that maintain continuous cutting without tool dwell. These processes help produce dimensionally accurate Titanium Machined Parts with the surface finish and material integrity required for demanding aerospace, medical, and industrial applications.

Titanium Grade Selection

Two titanium grades serve a large portion of precision machining applications:

Grade 2 — Commercially Pure Titanium (CP-Ti)
Grade 2 titanium offers excellent corrosion resistance, including in many chloride and seawater environments. With moderate strength and good formability, it is commonly used for chemical processing, marine hardware, and selected medical applications.

Grade 5 — Ti-6Al-4V / Ti-6Al-4V ELI
Grade 5 is one of the most widely used titanium alloys, containing approximately 6% aluminum and 4% vanadium. It provides high strength, excellent strength-to-weight performance, and good corrosion resistance. Grade 5 is widely used in aerospace structures, fasteners, and high-strength components. Ti-6Al-4V ELI has tighter limits on certain interstitial elements and is commonly specified for medical implant applications.

      Frequently Asked Questions

      Q: What is the difference between Grade 5 and Grade 5 ELI titanium?

      A: Grade 5 (Ti-6Al-4V) and Grade 5 ELI (Extra Low Interstitial, ASTM F136) are compositionally similar but ELI has lower maximum limits for oxygen, nitrogen, and iron. ELI is specified for permanent implant applications where fatigue performance and biocompatibility under cyclic loading are critical.

      Q: Why does titanium machining cost more than steel or aluminum?

      A: Titanium’s low thermal conductivity concentrates heat at the tool tip, requiring lower cutting speeds (approximately 1/5 of aluminum speeds) and more frequent tool changes. Longer cycle times, higher tooling cost, and premium titanium material all contribute to higher per-part cost. The tradeoff — titanium’s strength-to-weight ratio and corrosion resistance — justifies the cost premium for the applications where it is specified.

      Q: Can RPM machine titanium for medical implants?

      A: Yes. We machine Grade 5 ELI per ASTM F136 and Grade 2 per ASTM F67 for medical implant applications. Material traceability, process controls appropriate for implant component production, and documentation per ISO 9001 requirements are standard on medical titanium orders.

      Q: Can RPM verify material certification for titanium?

      A: Yes. We source titanium with AMS 4928 (Grade 5) or ASTM B265/F136 (Grade 2) certification. Material heat numbers are recorded and referenced to specific production lots. Copies of mill certifications are available with delivery on request.
