Custom Precision CNC Machined Magnesium Alloy Parts

FlexiTurn provides precision CNC machining for wrought magnesium alloy components, such as spoked optical support frames. AZ31B offers a high strength-to-weight ratio and excellent vibration damping, but its reactivity and low melting point make thin-wall machining demanding. Our magnesium-specific milling processes and low-distortion fixturing support consistent geometric accuracy and controlled surface quality for optical-grade applications.

FlexiTurn executes the full production sequence in-house, with process parameters and fixturing engineered specifically for wrought magnesium alloys to support repeatable accuracy and minimal residual deformation.

• 4-Axis CNC Milling: All primary features — inner and outer ring profiles, radial support spokes, mounting bosses, and mating faces — are completed in a single setup on 4-axis machining centers. This reduces re-clamping positional error and clamping-induced distortion in thin-wall sections. Cutting speeds, feeds, carbide tooling, and minimum quantity lubrication (MQL) cooling are calibrated for magnesium to minimize surface burning, suppress built-up edge, and control cutting heat.
• Precision Drilling & Tapping: Mounting through holes and threaded holes are machined with calibrated feeds and speeds, with controlled chip evacuation to avoid friction-induced ignition risk. All hole edges are deburred and blended to reduce stress risers.
• Secondary Operations: Vibratory deburring, surface finishing, and magnesium-specific protective treatments including micro-arc oxidation (MAO) and hard anodizing are available upon request to enhance corrosion resistance and surface wear performance.

FlexiTurn works with certified wrought magnesium alloys, providing original mill test reports and batch traceability for every order.

Standard material: AZ31B wrought magnesium alloy; alternative grades including AZ91D and WE43 available upon request

General dimensional tolerance: ±0.02 mm for features ≤ 50 mm nominal size

Geometric tolerances: Concentricity ≤ 0.015 mm for features ≤ 100 mm OD; wall thickness variation ≤ 0.02 mm for thin-wall sections

Surface finish: Ra 1.6–3.2 μm for standard milled surfaces

FlexiTurn’s machining cells are purpose-configured for magnesium alloys, with validated cutting data, low-force soft-jaw fixturing, and MQL cooling systems. This controls cutting heat, minimizes residual stress, and delivers uniform wall thickness and stable geometric form.

Repeated re-fixturing is a common cause of positional error and distortion in thin-wall magnesium frame components. FlexiTurn completes all profile, face, and radial hole features in one 4-axis setup, reducing cumulative fixturing error and supporting concentricity and hole position accuracy for consistent optical alignment.

All operations — from incoming material certification to final inspection — are performed under FlexiTurn’s direct control without subcontracting. Our magnesium machining cells are equipped with dedicated dust extraction and fire suppression systems to meet process safety standards. Material batch traceability is maintained from mill certificate to finished part.

Every CAD submission receives a Design for Manufacturability assessment focused on magnesium thin-wall optical component constraints. Our engineering team evaluates wall thickness transitions, spoke geometry, tolerance allocations, and mounting features to reduce production risk and improve part quality.

All production adheres to FlexiTurn’s ISO 9001:2015-aligned quality management system. Every shipment includes dimensional inspection records and original material test reports. Magnesium-specific surface treatment and certification packages are available upon request for high-criticality applications.
