# Titanium CNC Machining

Precision CNC milling and turning of titanium alloys for aerospace structural components, defense hardware, and medical device parts. Olympus Machining is a U.S.-based, ITAR-registered CNC machine shop in Hanover, Pennsylvania (CAGE 9V9P0).

## Titanium Grades We Machine

-   **Ti-6Al-4V (Grade 5):** The aerospace workhorse — 6% aluminum, 4% vanadium. Tensile strength ~950 MPa (138 ksi), density 4.43 g/cm³. Used for airframe brackets, defense fasteners, and orthopedic implants per ASTM F136 / AMS 4928.
-   **Ti CP Grade 2:** Commercially pure titanium. Lower strength (~345 MPa / 50 ksi) but excellent corrosion resistance and biocompatibility per ASTM F67. Used for medical implants, chemical processing components, and marine hardware.
-   **Ti-6Al-4V ELI (Grade 23):** Extra-low-interstitial variant of Grade 5 for surgical implants and cryogenic service per ASTM F136.

## Machining Approach

Titanium is notoriously difficult to machine. Low thermal conductivity concentrates heat at the cutting edge, work-hardening and built-up edge are common, and chemical reactivity with tool coatings shortens tool life. Olympus Machining runs titanium with coated carbide tooling at reduced surface speeds (typically 60–100 SFM for Ti-6Al-4V), high feed rates per tooth, climb milling strategies, and flood coolant to evacuate heat and chips. For deep pocketing, we use trochoidal toolpaths to control radial engagement and protect tool life.

Rigidity matters. Titanium's modulus is roughly half that of steel, so workholding and tool overhang are sized to suppress deflection and chatter — particularly on thin-wall aerospace structural parts.

## Typical Tolerances & Finish

-   ±0.001″ on milled features, ±0.0005″ on precision turned ODs and bores
-   Ra 0.4–0.8 µm achievable as-machined; finer with polishing pass
-   AS9102 Rev C First Article Inspection on aerospace and defense orders
-   Material certifications and Certificates of Conformance with every shipment

## Typical Applications

### Aerospace & Defense

Airframe brackets, suppressor end caps, missile components, fasteners, structural ribs, and engine-adjacent hardware.

### Medical Devices

Surgical instrument bodies, dental abutments, orthopedic implant components, and biocompatible structural parts.
