Custom CNC Machined Titanium Flange Parts

FlexiTurn delivers precision CNC machining for titanium and titanium alloy components, such as stepped flanged sleeves with bolt circle holes.

Titanium alloys like Ti-6Al-4V offer a high strength-to-weight ratio, excellent corrosion resistance, and well-known biocompatibility, making them suitable for demanding aerospace, medical, and high-performance industrial applications. However, titanium’s high chemical reactivity, strong work hardening tendency, and low thermal conductivity make it challenging to machine accurately. FlexiTurn applies dedicated titanium machining processes to minimize surface tearing, dimensional drift, and excessive tool wear, helping preserve the alloy’s mechanical and corrosion performance while maintaining tight, repeatable tolerances.

FlexiTurn executes the full production sequence in-house, with process parameters calibrated exclusively for titanium alloys to ensure repeatable precision and material integrity across every batch.

• CNC Turning: All rotational features — outer diameter steps, internal bore, sealing shoulders and chamfers — are completed in a single lathe setup. This eliminates re-clamping positional error and guarantees consistent concentricity between bore, flange face and outer diameter. Cutting speeds, feeds, carbide tooling grades and high-pressure coolant delivery are optimized for titanium to minimize work hardening, control cutting heat and prevent subsurface plastic deformation.
• CNC Milling & Precision Drilling: Flange faces, bolt circle holes and locating features are machined via 3-axis CNC milling with indexed fixturing, ensuring accurate bolt hole spacing and true position relative to the central bore. All hole edges are deburred and blended to minimize stress risers in high-load service environments.
• Secondary Operations: CNC internal/external grinding for critical sealing surfaces, stress-relief heat treatment, and precision surface finishing are available on request to meet specific application requirements.

FlexiTurn works with certified premium titanium materials, with full mill test reports and batch traceability for every order.

• Standard grades: Ti-6Al-4V (Grade 5); commercially pure titanium Grade 2
• Medical grade: Ti-6Al-4V ELI (Grade 23) for implant and surgical device applications
• Alternative titanium alloys available on request
• General dimensional tolerance: ±0.02 mm for features ≤ 50 mm nominal size
• Geometric tolerances: Flange face flatness ≤ 0.005 mm; bore-flange concentricity ≤ 0.01 mm for features ≤ 50 mm OD
• Surface finish: Ra 1.6–3.2 μm for standard machined surfaces; Ra 0.8–1.6 μm for ground sealing faces

Most CNC shops run titanium parts on repurposed steel or aluminum parameters, resulting in surface galling, excessive tool wear and subsurface work hardening that degrade fatigue and corrosion performance. FlexiTurn’s machining cells are purpose-configured for titanium alloys, with validated cutting data, dedicated high-performance tooling and high-pressure coolant systems. This produces clean, tear-free surfaces and consistent dimensional accuracy, preserving the full strength and corrosion resistance of the base material.

Repeated re-fixturing is the primary cause of concentricity and flatness error in flanged sleeve components. FlexiTurn completes all primary rotational features in one lathe setup and maintains aligned fixturing through secondary milling operations, minimizing cumulative positional error. This delivers uniform sealing performance and interchangeable fit across every production batch.

All operations — from incoming material certification to final inspection — are performed on FlexiTurn’s premises with zero subcontracting. This reduces lead time variability, eliminates third-party markup and maintains direct oversight of every quality-critical step. Full material batch traceability is maintained from mill certificate to finished part, and all production adheres to our ISO 9001:2015-aligned quality management system.

Every CAD submission receives a complimentary Design for Manufacturability assessment within 24 hours, focused on titanium processing constraints and application performance. Our engineering team evaluates wall thickness transitions, bolt hole patterns, tolerance allocations and corrosion allowance to mitigate production risk, optimize cost and maximize component service life.

FlexiTurn leverages a mature manufacturing ecosystem to deliver competitive pricing without compromising quality. We support orders from single prototypes to high-volume production, with dedicated project managers providing transparent, regular communication throughout every project. Your designs and intellectual property are fully protected by our strict confidentiality protocols and NDA frameworks.
