Titanium CNC Machining

VisionForge machines titanium parts — primarily Ti-6Al-4V (Grade 5) — for aerospace, defence, and medical device customers out of our Mississauga, Ontario facility. Simultaneous 5-axis on a 2025 Matsuura MX-520 and 3-axis on a Fanuc Robodrill α-T14iAL, inside a climate-controlled environment held at 20°C ±1°. Titanium is notoriously sensitive to tool pressure, heat buildup, and thermal drift — which is why we run it on rigid, modern equipment in a stable thermal environment, with cutting strategies built around the material rather than scaled up from aluminum practice.

Why our shop suits titanium work

Titanium work punishes shops that weren't set up for it. Three things on our floor matter for this material:

• Rigidity of the MX-520. The 2025 Matsuura MX-520 is a box-way-equivalent simultaneous 5-axis platform with a 20k RPM spindle and 1 micron repeatable accuracy. Rigidity and thermal stability at the spindle are what keep Ti-6Al-4V from chattering, work-hardening, and tearing tools apart on long contour passes.
• Climate-controlled facility held at 20°C ±1°. Titanium's coefficient of thermal expansion is roughly half that of aluminum, but a titanium part with tight GD&T still walks between morning and afternoon if the shop floor drifts 5°C across the day. Our shop doesn't drift.
• Cutting strategy, not just equipment. Titanium asks for slow-and-deep on roughing, high-speed trochoidal on slotting, and positive-rake geometries on finishing. The programs are built that way from the first article, not retrofitted after a scrap run.

Titanium grades we machine

• Ti-6Al-4V (Grade 5) — the workhorse alpha-beta alloy. Aerospace structural brackets, housings, medical instruments, optics mounts. Most of our titanium work is this grade.
• Ti-6Al-4V ELI (Grade 23) — the low-interstitial variant used in medical implants and cryogenic applications. Lower oxygen content, tighter material cert requirements.
• Commercially pure titanium (Grades 1–4) — softer, more corrosion-resistant, common in chemical and medical hardware. Machined on the Robodrill for 3-axis work or on the MX-520 for contoured parts.
• Ti-6Al-2Sn-4Zr-2Mo (Ti-6-2-4-2) — higher-temperature titanium for aerospace hot-section components. Available on request.

Other grades (Ti-5553, Ti-15-3-3-3, etc.) on request with material lead time and cert requirements discussed up front.

Tolerances and surface finishes

• In-house tolerance: ±0.0001" on features where the drawing calls for it, on both the MX-520 and the Robodrill.
• Final CMM verification: ±0.0002" through our ISO 9001 partner.
• Surface finish: down to ~16 µin Ra on finished titanium surfaces with the right tool and strategy. Specify Ra target on the drawing; we won't guess.
• Edge condition: in-house vibratory finishing is available for deburring, edge break, and pre-coating surface prep as a machining add-on.

Common titanium part types

• Aerospace structural brackets and fittings in Ti-6Al-4V
• Aerospace and defence housings — hydraulic, optical, and instrument housings
• Medical instruments — surgical guides, drivers, reamers, and retractor components in Grade 5 and Grade 23
• Optical and photonics mounts — titanium gives mechanical stability with low mass
• Prototype and short-run production for titanium parts where a proto shop's lead times and a production shop's documentation are both required

Documentation available

• Material certifications — traceable to the mill, available on request
• First Article Inspection (FAI) reports — AS9102 format on request
• PPAP-style documentation — prepared per the customer's format requirements
• CMM dimensional reports — partner CMM inspection to ±0.0002"
• Partner operation records — turning, grinding, and CMM documentation delivered with the parts when partner ops are in scope

Industries this material supports

• Aerospace CNC machining — titanium is the defining material of modern aerospace structural work. AS9100D in process.
• Defence CNC machining — CGP registration under Government of Canada review.
• Medical device machining — Ti-6Al-4V and Grade 23 for implant-adjacent work, under the customer's ISO 13485 QMS.
• Optics, photonics, and industrial automation — titanium mounts where thermal stability and stiffness-to-weight matter.

FAQ

Can you machine Ti-6Al-4V to tight tolerances?

Yes. We hold ±0.0001" in-house on the 2025 Matsuura MX-520 and the Fanuc Robodrill α-T14iAL, with final CMM verification to ±0.0002" through our ISO 9001 partner. Titanium's behaviour on finishing passes is predictable in our 20°C ±1° climate-controlled facility.

Do you supply material, or does the customer?

Either. Most customers supply their own material with cert. When we source, we buy from qualified mills and pass the mill cert through to the customer on request.

What titanium grades do you work with?

Primarily Ti-6Al-4V (Grade 5) and Ti-6Al-4V ELI (Grade 23). Commercially pure grades 1–4 and Ti-6-2-4-2 are available. Other grades on request.

What part volumes make sense?

Prototype through low-volume production, typically 1 to 500 pieces. Lights-out unattended production is available on the palletized MX-520.

Can you provide FAI reports on titanium parts?

Yes. FAI reports are available on request, prepared per AS9102 or per the customer's format.

Do you offer surface treatments for titanium?

Anodising, passivation, and coating services are coordinated through qualified finishing partners per customer PO.
