Difficult-Alloy Precision CNC Machining
Grade 5 Titanium Prototype Parts
We machine Grade 5 Titanium (Ti‑6Al‑4V) prototype parts for engineering teams that need manufacturability, controlled processes and inspection evidence—not just a unit price. From first article through low‑volume and repeat orders, we plan the process around titanium’s behavior so your prototypes arrive dimensionally stable, clean and ready for validation.

What you get when we machine your Grade 5 Titanium prototypes
Every project is planned around titanium’s unique behavior in machining, so you receive parts that are dimensionally stable, clean and ready for validation.
Faster design validation with fewer do‑overs
- Rapid DFM feedback on thin walls, tool access, thread forms and datums, so you can lock down interfaces earlier and avoid late changes.
- Prototype lead times start at 5–10 business days, helping you build test rigs, run fit checks and release tooling on schedule.
Stable tolerances on thin, complex features
- 5‑axis strategies, fixture planning and minimized setups keep tolerance stacks tight on complex contours, pockets and precision interfaces.
- We select cutter paths and step‑downs that manage heat and deflection in Ti‑6Al‑4V, reducing spring‑back, chatter and rework.
Titanium‑appropriate surface and edge quality
- Controlled feeds and finishing passes deliver machined finishes down to Ra 0.8 μm; grinding can reach Ra 0.2 μm where needed.
- Deburring and cleaning plans are defined up front, so threads, seal faces and edges are inspection‑ready out of the box.
Traceability and inspection you can sign off
- Material traceability, First Article Inspection, ballooned drawings and dimensional reports are available to meet aerospace, medical and semiconductor requirements.
- We align inspection strategy with your critical features and provide project‑specific quality records.
Dependable communication and project control
- A single point of contact coordinates engineering, procurement and quality updates so stakeholders stay aligned.
- We flag risks early (tool access, tolerance interactions, special processes) with documented countermeasures to reduce supply risk.
Best‑fit use cases
- Aerospace brackets, housings, impellers, blades and precision interfaces
- Medical instrument components and non‑implant fixtures per drawing
- Semiconductor vacuum and process components with demanding surfaces
- Energy, oil and gas and robotics parts requiring thin walls and tight GD&T
- High‑value prototypes, low‑volume and high‑mix repeat programs
Our approach to Ti‑6Al‑4V machining
Grade 5 Titanium’s low thermal conductivity and high strength concentrate heat at the cutting edge and can cause work hardening, burr formation and spring‑back. We address this by:
- Selecting geometries and toolpaths that balance engagement and heat input on thin sections
- Planning fixtures to shorten tool overhangs and reduce deflection
- Sequencing rough/finish passes to control stress and dimensional drift
- Applying special processes—EDM for sharp internal corners, grinding for precision bearing fits, and application‑appropriate finishing, deburring and cleaning
- Defining inspection features and probing strategies before the first chip to avoid surprises at final inspection
