Comparable scope

Align finish, secondary operations, packaging, delivery, and exclusions.

CNC milling titanium: a project-specific RFQ checklist

Specify the titanium material

State the alloy and condition required by the drawing or purchase specification. If alternatives are allowed, identify the approval process. Keep material details consistent across the model, drawing, and order documents.

Mark critical geometry

Provide a current drawing and matching model with units, part number, revision, quantity, datums, and functional features. Highlight thin sections, deep features, interfaces, or surfaces that need special review without assuming the supplier can meet an unstated tolerance.

Define surface and secondary requirements

State finish, edge, marking, cleaning, or outside processing requirements. Identify surfaces used for assembly or inspection and explain whether checks occur before or after any secondary operation.

Agree on material documentation and inspection

List the requested material records, inspection results, and acceptance criteria. If the project has customer or industry documentation needs, include them in the RFQ and ask the supplier to confirm what is available.

Compare quotes with the same assumptions

Align alloy, condition, quantity, machining scope, finish, inspection, records, packaging, and delivery assumptions. Ask for written confirmation of substitutions and exclusions before approval.

See CNC milling capabilities and metal material information, then share the drawing through the quote request page.

Frequently Asked Questions

What should a CNC milling titanium RFQ include?

Include alloy and condition, current drawing and model, revision, quantity, functional features, finish, inspection, and documentation needs.

Can the supplier choose the titanium grade?

Only if the design allows it. State required properties and obtain approval for the exact grade before ordering.

Should the drawing identify critical tolerances?

Yes. Mark dimensions and surfaces that control function and state the applicable acceptance criteria.

How do I compare titanium milling quotations?

Compare the same material, condition, revision, quantity, operations, finish, inspection, documentation, exclusions, and delivery assumptions.

How much does CNC milling titanium typically cost, and what factors influence the pricing?

CNC milling titanium is significantly more expensive than machining aluminum or steel, with typical costs ranging from $75 to $200 per hour of machine time, plus material costs. Titanium alloy stock (e.g., Ti-6Al-4V) can cost 10 to 20 times more than aluminum per pound. Key factors influencing price include part complexity (more intricate geometries require longer cycle times), quantity (higher volumes reduce per-part setup costs), and tolerance requirements (tighter specs demand slower feeds and more inspection). Material waste is also a factor, as titanium is often ordered in near-net shapes to reduce scrap. Additional costs may arise from specialized tooling, coolant systems, and post-machining treatments like stress relieving or passivation. For a simple bracket, expect to pay $200–$500, while complex aerospace components can exceed $5,000. Always request a detailed quote that includes setup, material, and finishing costs.
