Why Titanium Is Different

Hard to Machine, Worth the Effort

01

Material Difficulty

Titanium alloys generate high cutting heat and strong tool wear. Poor parameter control can cause chatter, surface tearing, and dimensional drift.

02

Machining Strategy

We use rigid fixturing, coated carbide tools, and controlled feed rates. Coolant flow and cutting paths are optimised to reduce heat and maintain tool life.

03

Stable Results

You receive titanium parts with clean surfaces and reliable tolerances. Suitable for aerospace brackets, medical fixtures, and structural components.

Precision Manufacturing

Titanium CNC Machining Services

3-Axis & 5-Axis Milling

Complex Geometry

We machine Ti-6Al-4V and commercially pure titanium, and are capable of thin walls, deep cavities, and multi-surface positioning in a single setup.

Precision Turning

Tight Concentricity

CNC turning for shafts, pins, and threaded parts. We control roundness and surface finish for critical rotating and mating features.

Surface Finishing

Functional & Cosmetic

Bead blasting, polishing, anodizing, and passivation are available. These improve corrosion resistance and appearance without changing dimensions.

Prototype & Production

Flexible Volume

From single prototypes to batch production. Process planning is adjusted for stable quality and repeatable delivery.

Thin-Wall Machining

Down to 0.5 mm

Titanium deflects under cutting force, so thin sections are supported and cut in staged passes rather than forced in one operation.

Certified Material Routes

ASTM / AMS / ISO

Production to ASTM B348 and F136, AMS 4911 and 4928, and ISO 5832-3, with mill certificates traceable to the heat number.

Material Case

Why Choose Titanium Alloys for Critical Components?

Titanium alloys are essential for critical components because of their high strength-to-weight ratio. They are as strong as steel but 40% lighter. A natural oxide layer provides excellent corrosion resistance in seawater and chemicals. These alloys remain stable in extreme heat and sub-zero temperatures. In medical fields, titanium is biocompatible and safe for human implants. Although the material is difficult to machine, it ensures long-term reliability and safety.

  • As strong as steel at 40% less weight
  • Natural oxide layer resists seawater and chemicals
  • Stable from sub-zero temperatures to extreme heat
  • Biocompatible and safe for human implants

Thermal Stability

Advantages of CNC Machining Titanium Alloys

Titanium alloys maintain excellent mechanical strength at high temperatures up to 500°C. Their low coefficient of thermal expansion minimises dimensional changes during the CNC process. These properties ensure high precision and tight tolerances for critical components like engine blades. This thermal stability makes titanium ideal for demanding aerospace and industrial applications.

  • Mechanical strength retained up to 500°C
  • Low thermal expansion keeps dimensions stable in cut
  • Holds tight tolerances on engine blades and similar parts

The Engineering Challenge

The customer required a lightweight bracket for an aircraft interior system. The part had thin ribs, deep pockets, and several positional holes that had to remain within tight flatness limits after machining.

  • Controlling deformation during rough machining.
  • Maintaining perpendicularity between mounting faces.
  • Preventing tool wear from hard titanium stock.

Our Solution

We selected low-feed carbide tools and applied step-down roughing to reduce cutting stress. Final finishing was completed in a single setup to keep all datum surfaces aligned.

  • Tooling: Coated end mills for titanium alloys.
  • Setup: One-time clamping for all critical faces.
  • Inspection: CMM check on hole position and flatness.

FAQ

Addressing Your Concerns

  • We ensure high consistency between the first article and batch production through process control, data management, and on-site expertise, rather than relying solely on final inspection.

    First Article Inspection (FAI): once the first piece is processed, we perform a full dimensional inspection to verify critical dimensions, tolerances, and surface finish. Mass production only begins after FAI approval.

    In-process sampling: during mass production we conduct periodic dimensional checks according to the production beat, focusing on critical features and geometric tolerances (GD&T).

    Precision instrumentation: we use calibrated calipers, micrometers, and CMMs to ensure all measurement data is reliable.

    Material uniformity: for batch orders we unify the material source and can provide material certifications to ensure consistent performance across all units.

  • Yes. Depending on your requirements, we can provide the following material documentation:

    Mill Test Certificate (MTC) / Material Certificate: detailing the material grade, chemical composition, and mechanical properties.

    Material standards compliance: documentation showing adherence to ASTM, EN, JIS, or GB standards.

    Batch consistency statements: ensuring all parts in a large order originate from the same material lot.

    Note: if your project requires third-party testing or specialised material certifications, please specify this before the quotation stage so we can confirm the lead time and costs.

  • Yes. We fully support NDA execution and treat customer intellectual property protection as a fundamental engineering principle. Our specific measures include:

    Support for unilateral or mutual NDAs: NDAs can be signed before drawing review or quotation.

    Controlled access to technical data: customer drawings are accessible only to project-related engineering personnel.

    No outsourcing or public display: parts are not used for marketing, sample displays, or third-party demonstrations.

    No part retention or replication: finished parts are not retained or reproduced without written customer authorisation.

    We understand that for engineering-driven customers, the design itself is the core asset.

  • We take full responsibility for our machining quality and maintain a transparent, actionable after-sales policy:

    Immediate response: upon receiving feedback we respond immediately. If the product is found to be non-conforming due to our error, we provide a free remake or a full refund.

    Corrective action: we log the issue into our internal process records and perform a root-cause analysis to prevent recurrence in future orders.

    Solution-oriented: our goal is not to deflect responsibility, but to resolve the problem quickly and keep your project on schedule.

  • Surface treatment: if the treatment methods and requirements are clearly defined, they will be listed as a separate line item or integrated into the unit price. If requirements are unconfirmed, these are not included by default, to avoid misunderstandings later.

    Logistics costs: we offer various Incoterms including EXW, FOB, CIF, and DDP based on your needs. Shipping costs are typically listed separately to allow for easier cost comparison and accounting.
