OEM Titanium CNC Turned and Milled Parts Supplier

XCM CNC supplies custom titanium turned and milled parts to the drawing, with quality systems aligned to ISO 9001 and ISO 13485 and imported machines from brands such as DMG and Mazak covering TC4 and TA2 machining.

During DFM, we confirm likely alloy grade, critical tolerances, and the fixture route before sampling starts. The sample stage checks heat buildup and residual stress caused by low thermal conductivity, while MOQ starts from 1 piece and standard lead time is typically 10-15 days for high-value titanium parts that need strength, corrosion resistance, and lightweight performance.

DFM Review for OEM Titanium Drawings

Titanium OEM drawing review can lock +/-0.003 mm critical features and 0.015 mm position tolerance before sample approval. When the program changes between TC4 and TA2, includes 0.5 mm thin walls, or needs 0.01 mm hole position control, we confirm stock allowance, fixture datums, and the inspection scope during the sample review.

Sample Approval for Thin-Wall Titanium Parts

Titanium sample approval can reserve Ra 1.6 um mating faces and Ra 0.8 um turned or bored functional surfaces where the drawing requires them. When the geometry approaches 0.5 mm thin walls, H7 fits, or multi-face setups, the first article also checks heat buildup, springback, and the deburring range.

Revision Control for Critical Titanium Fits

Titanium revision changes should trigger a recheck of 0.012 mm coaxiality and 0.01 mm runout on shaft-bore and flange interfaces. When a revision affects deep cavities, long slots, or fit-critical faces, the toolpath, stock allowance, and reinspection order are reassessed around 0.02 mm flatness and +/-0.003 mm precision features.

Reinspection After Surface Protection

Titanium protected parts can keep Ra 3.2 um standard milled faces while reserving key areas for passivation or bead-blasting review. For high-strength connectors and corrosion-resistant structures, the post-sample route can recheck 0.015 mm hole position and 0.012 mm coaxiality with CMM data, FAI reporting, and material documentation.

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 a four-level CNC equipment mix across mainland China, Taiwan, Japan, and Europe or the US. Medium-tolerance titanium operations can run on domestic or Taiwan resources, while H7 fit faces and critical precision features move to imported machines such as DMG and Mazak. That helps lower machining cost without placing routine work onto high-hour equipment.

Grade Choice Locked Before the Sample Route

Differences between TC4 / Ti-6Al-4V and TA2 / CP Titanium in cutting load, strength target, and finishing support can be reviewed before sample approval so the grade choice does not disrupt quotation or process planning later. If the grade changes after the sample stage, we recheck the fixture plan, stock allowance, and reinspection scope around the critical faces.

Residual Stress Controlled Early

Thin-wall, deep-cavity, and high-specific-strength titanium parts can carry residual stress and heat buildup into later finish operations, so we confirm layered cutting, stress-control steps, and reinspection nodes early. That is more suitable for lightweight custom titanium work than applying a generic process borrowed from standard metals.
