High-Precision Titanium CNC Machined Parts Supplier
Overview
XCM CNC handles precision titanium machining with emphasis on critical tolerance control and matched inspection planning, supported by ISO 9001 and ISO 13485 aligned systems and imported machines from brands such as DMG and Mazak for TC4 and TA2 turning and milling.
Before machining starts, we confirm the fixture datum, position-tolerance route, and coaxiality measurement path to the drawing. The sample stage then checks how low thermal conductivity, heat buildup, and residual stress affect the critical features. MOQ starts from 1 piece and the route is suited to hole patterns, thin-wall structures, and sealing faces that need strict GD&T control.

GD&T Control for Precision Datums
Titanium precision datums can be reviewed against 0.02 mm flatness and 0.015 mm position tolerance before fixture release. For key datum faces, mounting holes, and freedom-sensitive structures, the CMM checks the geometry after a controlled setup against the drawing datum chain.
Single-Setup Datum for Hole Patterns
Titanium hole patterns can target 0.01 mm hole position and 0.012 mm coaxiality when the datum chain stays inside one setup. On thin-wall parts near 0.5 mm or fit-critical faces, H7 holes and h6 shaft positions are scheduled for finish machining only after heat-input and springback risk are reviewed.
Surface Roughness Control for Mating Features
Titanium mating features can combine Ra 1.6 um bored faces with Ra 0.8 um turned diameters for critical-fit evaluation. For hole patterns, end faces, and coaxial features, roundness to 0.006 mm can be checked on the roundness tester, while runout to 0.01 mm must follow the same agreed measurement datum.
Post-Finish Reinspection for Critical Areas
Titanium critical areas can hold selected +/-0.003 mm features after finishing only when reinspection follows the same datum plan. After passivation or bead blasting, the route checks whether 0.02 mm flatness and 0.015 mm position tolerance need to be reverified before release.

Applications
Medical Device Housings with Sealing Features
Typical Parts: Surgical robot joint housing, endoscope handle body, imaging-equipment mounting bracket
Titanium offers a strong mix of strength-to-weight ratio, sterilization resistance, and biocompatibility for lightweight non-implant structures. For thin-wall housings and sealing grooves, the route confirms a 0.015 mm positional-control datum and a stable fixture path for walls near 0.5 mm, while sealing-groove depth can be controlled to 0.01 mm where the drawing requires it.
Linear Module Bases and Vacuum Interface Fits
Typical Parts: Collaborative robot arm segment, high-rigidity servo motor end cap, vacuum end-effector flange
Titanium balances high specific strength with corrosion resistance for high-strength connectors and vacuum interfaces in specialized service. On flange faces and coaxial holes, the route focuses on 0.012 mm coaxiality and 0.02 mm flatness, while vacuum sealing surfaces can be bored or precision milled to Ra 0.8 um when required.
Chemical Sealing Interfaces and Valve Fits
Typical Parts: Precision valve seat, corrosion-resistant sealing flange, reactor outlet fitting
Titanium is well suited to small-batch, high-value valve seats and sealing fittings in corrosive-media service. Sealing-face roughness can be controlled to Ra 0.8 um, thread fit can be checked by go and no-go gauges, and 0.01 mm hole-position verification helps reduce leakage risk after assembly.
High-Performance Sports Supports and Fit-Critical Connectors
Typical Parts: Precision locating pin shaft, high-strength bolted connector block, articulated-joint pivot
Low weight together with high strength makes titanium suitable for repeatedly assembled and weight-sensitive sports structures. Hole-group position can be controlled to 0.01 mm, shaft runout to 0.01 mm, and h6 outer diameters plus H7 locating holes can be finished to Ra 0.8 um where the drawing requires them.
Why Choose Us
Qualified Systems and Equipment Coverage
XCM CNC organizes titanium projects under ISO 9001, ISO 13485, IATF 16949, and GJB9001C aligned quality systems while using equipment from brands such as DMG, Mazak, Matsuura, and Brother for turning, milling, and multi-face machining. For TC4 and TA2 programs, we review material certificates, thin-wall risk, and surface-protection requirements during drawing review.
Broad Size Range for Titanium Parts
We support machining from small connector-scale titanium parts to larger vacuum interfaces, corrosion-resistant structures, flanges, fasteners, and thin-wall precision components. Three-axis travel reaches 3000 x 1600 x 1400 mm and turning capacity reaches diameter 1250 x 2000 mm, while the final route still follows fixturing, alloy grade, and heat-buildup risk review.
Tiered Equipment Strategy for Cost and Quality
XCM CNC uses domestic, Taiwan, Japanese, and Europe or US sourced CNC equipment so standard titanium faces do not occupy imported-machine hours unnecessarily. Features such as 0.012 mm coaxiality and H7 fit holes move to DMG or Mazak class machines only when the drawing requires that level of precision.
Heat Drift Reviewed Early
Low-conductivity titanium parts can carry heat buildup into flatness, hole position, and fit-face variation, so we split the process by datum, operation stage, and measurement path before cutting begins. For high-precision flanges, vacuum interfaces, and thin-wall structures, the route confirms heat-drift risk and the reinspection nodes before the sample is released.
Datums and Inspection Defined Before Cutting
Position tolerance, coaxiality, and fit-face roughness are defined together with the setup datum and the reinspection method before machining starts. For key hole groups and sealing faces, the first article can be aligned to CMM, roughness, and go or no-go gauge checks instead of relying on a generic inspection path.
FAQ
What GD&T features can you control on precision titanium parts?
Common titanium GD&T targets include flatness to 0.02 mm, position tolerance to 0.015 mm, coaxiality to 0.012 mm, circular runout to 0.01 mm, and roundness to 0.006 mm. The final suitability still depends on part size, wall thickness, and the fixturing route reviewed against the drawing.
How do you inspect critical tolerances on titanium CNC parts?
Critical dimensions and GD&T features are commonly checked on the CMM, while roundness can be checked on the roundness tester and smaller features can be supported by the 2.5D video-measurement system. The measurement datum and report format are aligned to the drawing before cutting starts, and sample plus batch reporting can be separated when needed.
Can you achieve tight roundness and cylindricity on titanium turned parts?
Roundness to 0.006 mm and cylindricity to 0.011 mm are achievable on selected titanium turned features used in bearing fits, seals, and rotating parts. On parts with large length-to-diameter ratios or low wall stiffness, chatter and distortion risk still need staged review before those limits are assumed.
How thin can a titanium CNC wall be on custom parts?
A reference thin-wall limit around 0.5 mm is possible on some titanium parts, but the final feasibility depends on length, aspect ratio, residual stress, and the fixturing path. Deep cavities, long edges, and high-strength lightweight structures usually need layered cutting and reinspection planned together.
Can you control flatness, position, and coaxiality on precision titanium parts?
Yes. Titanium parts can be reviewed for flatness, position tolerance, and coaxiality with common reference values such as 0.02 mm flatness, 0.015 mm position tolerance, and 0.012 mm coaxiality. The final route still depends on part size, wall thickness, heat buildup, and the agreed inspection method.
How do you reduce heat-buildup drift on low-conductivity titanium parts?
Low-conductivity titanium parts usually rely on layered cutting, staged reinspection, and datum management to reduce dimension drift caused by heat buildup. Thin walls, deep cavities, and fit-critical faces also need the fixturing path and any stress-control step reviewed before the final route is approved.
