Aerospace Titanium CNC Machining Services

Machining complex aerospace geometries — compound-angle brackets, twisted airframe nodes, and thin-walled bulkheads — in a single clamping operation. Eliminates positional errors from re-fixturing.

• Adaptive trochoidal tool paths limit radial engagement to <10% of tool Ø — suppresses vibration on thin-wall structures
• Real-time spindle load feedback prevents work-hardening glazing on previously cut Ti-6Al-4V surfaces
• Achieves Ra 0.4 µm surface finish on aerospace structural brackets — eliminates secondary benching operations

Finite Element Analysis (FEA)-driven toolpath compensation predicts and counteracts tool deflection during thin-wall aerospace section milling. Closed-loop feedback ensures dimensional accuracy.

• FEA-predicted tool deflection maps adjust feed-rate in real time — eliminates trial-and-error cutter passes
• Adaptive feed-rate control reduces radial engagement below 10% of tool diameter, eliminating work-hardening glazing
• Maintains geometric accuracy on high-aspect-ratio wall sections down to 0.5 mm thickness

Grade 19 Beta Titanium (Timetal 19) is the material of choice for high-strength aerospace fasteners and hydraulic valve stems — offering 1,240 MPa tensile strength with excellent corrosion resistance. Our CNC Swiss lathes hold tolerances to ±0.005 mm on small-diameter turned profiles.

• Precision-ground single-point form tools for consistent UNJF/MJ thread root radii — eliminates notching fatigue
• Micro-finishing pass on hydraulic stem seal diameters — Ra 0.2 µm surface finish for zero-leak applications
• Full thread-form inspection via optical comparator — 100% compliance with AS8879, MIL-S-8879C thread standards

Thread root geometry is the primary stress concentration site in aerospace fasteners. Our Swiss turning process controls thread root radius to eliminate notching, and applies post-process stress relief to maximize high-cycle fatigue life.

• UNJF/MJ thread root radius controlled to AS8879 specification — eliminates sharp corners that initiate fatigue cracks
• Post-process thermal stress-relief cycle at 315°C for 2 hours — reduces residual tensile stresses by 40%
• Fatigue test verification per ASTM E466 — 10⁷ cycle minimum runout demonstrated on production lots

Our in-house metrology lab is equipped with ZEISS CMM platforms capable of measuring complex aerospace geometries — brackets, bulkheads, valve stems, and threaded fasteners — with volumetric accuracy of ±1.9 µm. Every dimensional characteristic per the engineering drawing is captured, analyzed, and reported.

• Full 5-axis CMM scanning with adaptive probe path planning — reduces inspection time by 60% vs touch-trigger
• ZEISS CALYPSO metrology software — native GD&T callout interpretation and true-position reporting
• Temperature-controlled lab (20°C ±0.5°C) — eliminates thermal expansion error on titanium components

All aerospace components are measured and reported to ASME Y14.5 GD&T standards. Our metrology team interprets every drawing callout — from simple flatness to complex profile-of-surface — ensuring full compliance with engineering requirements.

• GD&T callout interpretation: flatness, parallelism, perpendicularity, position, profile, runout
• Datum reference frame alignment — ensures measurement consistency across first article and production runs
• SPC data trending — early detection of tool wear, thermal drift, or fixture variation
