OEM CNC machined titanium alloy parts per specific drawings in China
We are a China-based precision machining workshop focused on titanium CNC machining in China for customers worldwide. We manufacture CNC machined titanium parts strictly per customer-specific drawings, 3D models, or supplied samples — from a single piece of titanium part prototype machining to repeat batches and high-volume production. Whether a project calls for CNC machining titanium grade 5 per drawing, CNC machined grade 2 titanium hardware, or CNC machined TC4 load-bearing components, every part is produced to the dimensions, tolerances, threads, and surface requirements defined on the print.
As an OEM machined titanium component supplier, we work from STEP, IGES, X_T, DWG, DXF and PDF files as well as physical samples. When only a used or reference part exists, sample-based reverse engineering rebuilds the geometry before production. Every batch of custom machined titanium hardware is delivered deburred, cleaned, and finished exactly as specified, ready for assembly.
Per drawing & per sample
Manufacture to customer prints or CAD models, duplicate supplied samples, and rebuild geometry by reverse engineering when no drawing is available.
Titanium-specific know-how
Tool paths, feeds, speeds, sharp tooling, high-pressure coolant and rigid fixturing are tuned for titanium's low thermal conductivity and high strength.
One piece to large volume
One-off titanium part prototype machining, first articles, small batches and recurring mass production all follow the same controlled process.
Broad grade coverage
Commercially pure grades 1–4, Ti-6Al-4V grade 5 / TC4, ELI grade 23, grade 9 3Al-2.5V, grade 7 palladium-bearing and common Chinese GB grades.
CNC machined titanium parts we produce
A quick look at recent custom CNC machined titanium work — turned fittings, milled connectors and multi-process OEM titanium components made entirely to customer drawings.
Titanium alloy grades we machine, across standard systems
Titanium is specified under several parallel standard systems — ASTM International and AMS in the US, GB/T in China, ISO internationally, JIS in Japan, and DIN in Germany. We read prints written in any of these systems and confirm the equivalent grade before the first cut. Below are the grades most often used for CNC machined titanium parts, together with their common cross-standard equivalents.
Commercially pure, maximum ductility
The softest and most formable commercially pure grade, with excellent corrosion resistance and good weldability. Typical CNC machined grade 1 titanium work includes gaskets, anode baskets, sensor shells, deep-drawn bodies and chemical-industry hardware. Equivalent references: ASTM B348 Grade 1, GB/T TA1, JIS class 1, DIN 3.7025.
The general-purpose workhorse
Balanced strength, ductility and weldability make grade 2 the most common choice for general CNC machined grade 2 titanium parts — flanges, fasteners, pipe fittings, marine hardware, heat exchanger components and pump bodies. Equivalent references: ASTM B348 Grade 2, GB/T TA2, JIS class 2, DIN 3.7035.
Higher-strength pure titanium
Noticeably stronger than grade 2 but slightly less formable, grade 3 is selected for CNC machined grade 3 titanium valve internals, high-pressure fittings, support rings and structural hardware exposed to aggressive chemical environments. Equivalent references: ASTM B348 Grade 3, GB/T TA3, DIN 3.7055.
Strongest commercially pure grade
The highest-strength unalloyed titanium, with good fatigue resistance and outstanding corrosion performance. It is widely used for surgical instrument blanks, high-strength CP titanium fasteners and airframe details. Equivalent references: ASTM B348 Grade 4, DIN 3.7065.
The dominant alpha-beta alloy
Ti-6Al-4V accounts for the majority of titanium used worldwide and combines high specific strength with service to moderate temperatures. It is the default material for CNC machining titanium grade 5 per drawing and CNC machined TC4 load-bearing parts such as bolts, brackets, shafts and motorsport components. Equivalent references: ASTM B348 Grade 5, AMS 4928, GB/T TC4, DIN 3.7165.
Extra-low-interstitial medical grade
An ELI version of grade 5 with tightly controlled oxygen, nitrogen and iron content for improved fracture toughness and biocompatibility. Used for custom CNC machined titanium surgical guides, implant prototypes, bone-fixation trial parts and precision medical instrument components. Equivalent references: ASTM F136, AMS 4931, GB/T TC4 ELI.
Tubing alloy, strong and formable
A near-alpha alloy stronger than the CP grades with excellent cold formability — the standard alloy for seamless and welded titanium tubing. Typical CNC machined grade 9 titanium parts include tube fittings, ferrules, bicycle frameset components, hydraulic line parts and aerospace ducting details. Equivalent references: ASTM B338 Grade 9, GB/T TA18, AMS 4945.
Palladium-bearing corrosion grade
Grade 2 chemistry with a small palladium addition delivers outstanding crevice-corrosion resistance in hot chlorides and reducing acids. It suits CNC machined grade 7 titanium pump shafts, valve stems, reactor hardware and chemical-processing components. Equivalent references: ASTM B348 Grade 7, GB/T TA9, DIN 3.7235.
ASTM International (US)
ASTM B265 covers sheet and strip, B348 bar and billet, B381 forgings, B338 tubes, and F136 medical material. Grades are numbered Gr.1 through Gr.38 and appear on most internationally traded prints.
AMS aerospace series
Aerospace Material Specifications such as AMS 4928 (grade 5 bar), AMS 4911 (grade 5 sheet) and AMS 4931 (ELI) are frequently named on aviation and defense drawings.
GB/T standards (China)
The Chinese system uses TA for alpha and commercially pure alloys, TC for alpha-beta alloys and TB for beta alloys — for example TA1, TA2, TA7, TA9, TA10, TA18, TC4, TC4 ELI, TC11 and TB6.
ISO standards
ISO material designations appear on international prints; ISO 5832-2 covers unalloyed titanium and ISO 5832-3 covers Ti-6Al-4V for surgical implant applications, alongside general ISO titanium product standards.
JIS standards (Japan)
JIS H4600 for plate and JIS H4650 for tube define classes 1 through 4 for commercially pure titanium and TR/TP designations for corrosion-resistant tubular products.
DIN / material numbers (Germany)
DIN 17850 and 17860 series and Werkstoff numbers such as 3.7035 (grade 2) and 3.7165 (Ti-6Al-4V) are used on German and broader European engineering drawings.

Machining processes and inspection for titanium parts
Titanium CNC machining in China combines rigid machine tools, sharp dedicated tooling and aggressive coolant delivery with independent dimensional verification. The four core capabilities below cover most OEM machined titanium component requirements.
CNC milling service
3-axis, 4-axis and 5-axis CNC milling centers convert titanium plate, block and forgings into pockets, contoured surfaces, brackets and housings. Rigid fixturing, climb-milling strategies and high-pressure coolant keep heat away from the cutting zone, which is essential when CNC machining titanium grade 5 per drawing with thin walls or deep pockets.
CNC turning service in China
CNC lathes and sliding-head (Swiss-type) machines turn titanium bar and tube into fittings, shafts, sleeves and thin-wall tubular parts. Live tooling adds cross holes, flats, keyways and milled features in a single setup, so a custom CNC machined titanium fitting can go from bar stock to finished part without repeated handling.
2D profile projector measuring
A digital optical profile projector checks turned profiles, radii, chamfers, thread forms, angles and small-feature dimensions against the drawing. It is used for first-article inspection and in-process spot checks of CNC machined titanium parts such as tiny fasteners, ferrules and delicate ELI medical components.
CMM testing
A coordinate measuring machine verifies three-dimensional position, true position, flatness, parallelism, perpendicularity and other critical tolerances on milled and multi-axis work. Measured results can be recorded for first articles and production lots of OEM machined titanium component orders, providing traceable evidence that parts match the print.
Surface treatments for CNC machined titanium parts
Titanium develops a stable natural oxide film, but functional or cosmetic requirements often call for a defined secondary finish. The finishes below are applied after machining, per the callouts on the drawing or purchase specification.
Titanium anodizing
Type II anodizing grows a transparent interference oxide that shows gold, blue, purple, bronze or magenta depending on film thickness — widely used for color coding and appearance. Type III hard anodizing builds a thicker, more wear-resistant layer for moving custom machined titanium hardware.
Passivation
Nitric-acid or citric-acid passivation removes embedded free iron and surface contamination picked up during machining, restoring the natural corrosion-resistant oxide layer of CNC machined grade 2 titanium and grade 5 / TC4 parts.
Electropolishing
An electrochemical process that removes a thin uniform surface layer to produce a bright, smooth, particle-free finish with reduced roughness — a common choice for medical, laboratory and clean-service titanium components.
Mechanical polishing
Progressive abrasive and buffing steps move machined titanium from a machined finish through satin to a mirror polish, used for decorative parts, sealing surfaces and components that must resist adhesion or buildup.
Bead & sand blasting
Fine glass-bead or ceramic media create a uniform matte or frosted gray surface that hides tool marks and gives every piece in a batch of CNC machined titanium parts the same consistent appearance.
Brushing & satin finishing
Directional abrasive belts produce controlled linear satin textures on titanium plates, panels, consumer product parts and bicycle components, with defined grain direction and roughness range.
PVD & thin-film coatings
Physical vapor deposition adds a very thin, hard decorative or functional film in black, gunmetal or gold tones over machined titanium without meaningfully changing finished dimensions, suited to premium consumer and wear parts.
Laser marking & other finishes
Permanent part numbers, lot codes and logos are applied by depth-controlled laser marking or engraving. Vibratory tumbling, barrel finishing, thermal oxidation and powder coating are also available as supporting secondary finishes.
Titanium stock forms machining starts from
Choosing the right input stock reduces waste, controls cost and protects mechanical properties. We machine the following titanium forms in grades 1–4, grade 5 / TC4, ELI, grade 9 and specialty alloys.
Round bar
The most common input for CNC turning and Swiss-type work — shafts, pins, fasteners, fittings and bushings — in drawn, peeled or centerless-ground condition.
Plate & flat bar
Used for milled brackets, mounting plates, housings and structural details, with thickness selected to leave clean-up stock on all machined faces.
Seamless & welded tube
Grade 2 and grade 9 / TA18 tube is the efficient starting point for thin-wall bushings, ferrules, sleeves and fluid connectors, removing far less material than solid bar.
Sheet & coil
Thin sheet feeds laser-cut or waterjet-cut blanks that are then edge-machined, and supports shims, covers and lightweight enclosure details.
Wire
Small-diameter titanium wire feeds Swiss-type lathes and secondary rolling for micro fasteners, tiny pins and precision custom machined titanium hardware.
Forged billet & custom forgings
Forged block or near-net-shape forgings provide aligned grain flow for heavily loaded grade 5 / TC4 aerospace-style and motorsport components before finish machining.
From a single piece to large-batch production
Titanium part prototype machining and series production share the same equipment and inspection logic, so a validated prototype converts smoothly into repeat orders without redesigning the process.
One-off & prototype
Single-piece titanium part prototype machining, design-verification samples, first articles and fit-and-function builds, with fast turnaround on simple geometries.
Low-volume production
Pilot runs, spare parts and custom machined titanium hardware for niche products, where flexible setups keep tooling investment low.
Batch production
Recurring batches produced with dedicated soft jaws or fixtures, optimized cycle times and stable, repeatable quality lot after lot.
Mass production
High-volume OEM machined titanium component supply with planned material stocking, balanced multi-machine capacity and consistent lot-to-lot dimensions and finish.
How a drawing or sample becomes a finished titanium part
The same sequence applies whether the input is a fully dimensioned drawing, a 3D model, or a worn physical sample that needs duplicating.
Drawing or sample review
Dimensions, tolerances, threads, surface callouts and grade requirements are reviewed; manufacturability feedback is provided before production starts, and samples are measured for reverse engineering when needed.
Material confirmation
The correct grade is matched across ASTM, AMS, GB/T, ISO, JIS or DIN designations, and the appropriate stock form — bar, plate, tube or forging — is prepared.
Programming & fixturing
Tool paths are programmed for titanium-specific cutting data, and workholding — including soft jaws, vacuum or custom fixtures — is designed to protect thin walls and tight tolerances.
CNC machining
Milling, turning, multi-axis machining and secondary operations such as drilling, tapping, broaching and grinding produce the CNC machined titanium parts to the print.
Deburring & surface finish
Edges are broken and burrs removed, followed by the specified treatment — anodizing, passivation, polishing, blasting, brushing, PVD or laser marking.
Inspection, cleaning & packing
Dimensions are verified by projector, micrometers, gauges and CMM; parts are cleaned, separated to avoid scratching, and packed for shipment with inspection records when required.
