CNC Milling & Turning Services

Milling and turning are the verbs of machining. Everything else is punctuation.

Every shop mills and turns. Our floor runs the materials that fight back — Inconel, titanium, non-magnetic alloys, high-strength steels — on Mazak INTEGREX mill-turn centers that complete turned and milled features in one clamping. Single pieces to batch production, ±0.01 mm at the machine, every part verified by in-house metrology.

Why “Basic” Processes Are Where Quality Shows

Every shop claims milling and turning. The differences hide in the extremes:

Long parts deflect
An 8-meter shaft bends under its own weight and the cutting force. Steady rests, support strategy, and cutting parameters decide whether the middle of the shaft matches the ends
Thin walls distort
A thin-wall sleeve rings like a bell under the tool. Fixturing, sequence, and stress relief decide the final roundness, not the machine’s brochure
Difficult alloys punish routine
Inconel work-hardens mid-pass; titanium welds itself to a dull edge. “Standard” feeds and speeds simply do not exist for these materials — the parameter windows are learned, not looked up
Batch consistency is the real exam
Part #1 to print is machining; part #1,000 to the same print, same week, is discipline. Tool wear compensation, in-process checks, and frozen routings are what batch production actually runs on
Mill-turn removes the hand-off
Turning and milling in one clamping: no re-chuck error, no queue between machines, no datum drift between the round features and the milled ones

The Mill-Turn Centers We Import

Turning and milling are common. The materials we run are not. Our floor carries imported Mazak INTEGREX mill-turn centers — i-500S (to Ø700 × 3,000 mm) and i-400S (Ø650 × 2,500 mm) — that turn, mill, drill and bore a part in one clamping, so the datum never moves between operations.

A mill-turn center costs several times a comparable CNC lathe — capital that most general machine shops do not carry. We run them because our parts earn it: Inconel, titanium, non-magnetic P550 alloys, high-strength steels. Every re-clamping is a chance to lose a dimension, and on a mill-turn the finished surface comes straight off the machine — no grinding handoff downstream.

Over 100,000 part types have crossed this shop in three decades. The difficult ones are the reason these machines are here.

Where Our Turning & Milling Is Running

Industry	Application	The record
Oil & Gas	Drive shafts, drill collars, hydraulic control bodies — batch production	Manufacturing partner of a rotary-steerable drilling program in China
Marine	Engine shafts, common-rail adjacent components	Part of the deep-hole program built when the technology and equipment could not be bought; certified by 7 classification societies
Aerospace	Structural parts in nickel-base superalloys	Qualified supplier in a national civil aircraft program — precision semi-finishing
Robotics	Shafts & joint parts for manipulators	Deep-sea manipulator parts in production

Long shafts laid out on stands in a clean assembly bay — Long shafts, staged for assembly — the parts the steady-rest discipline is for

Representative Part Families

Drive shafts, drill collars, marine shaft lines, circuit frames — five families cover most of what crosses this floor. What separates them is not the shape — it is what the shape demands:

Part family	What it demands	Where it runs
Turned parts	Roundness, concentricity and straightness held over length — shafts, collars, sleeves, stepped spindles	Self-built FWT-80800 to Ø800 × 8,000 mm; steady-rest strategy for slender shafts
Long-bored parts	Deep, straight bores held over length in heavy-wall tubes — drill collars, stabilizer bodies	In-house deep-hole line, bore deviation ≤0.3 mm/m → Deep-Hole Drilling →
Milled parts	Flatness, hole position and pocket depth held across a large face — housings, bodies, plates, brackets	3/4-axis machining centres, FWV / FWH class, built in-house
Complex-contour parts	Compound-curve surfaces and blended transitions a 3-axis path cannot reach	5-axis simultaneous → 5-Axis Machining →
Flow-channel & cavity parts	Internal galleries, cross-holes and curved channels — milled open, then finished where no cutting tool can reach	5-axis milling + in-house EDM → EDM →
Fitting & connector parts	Threaded joints, sealing faces and compound-angle ports that must seal on assembly	Mill-turn in one clamping — Mazak INTEGREX i-500S & i-400S

FAQ

Q: What is your largest turning capacity?

Ø800 × 8,000 mm on our self-built FWT-80800; the shop’s overall envelope reaches Ø1,000 × 10,000 mm across processes. Beyond that, talk to us — combined processes on one floor solve most oversized parts.

Q: Do you take batch production orders?

Yes — batch programs for oilfield tools run on our floor today, with frozen routings and documented in-process checks at defined control points. Prototype quantities run through our Custom Manufacturing → line.

Q: Can you hold concentricity over long shafts?

Long-shaft concentricity is a support-and-process problem we solve daily — movable steady rests, sequence planning, and stress management — on slender shafts to 8,000 mm between centers on our self-built FWT-80800. Send the drawing; we will quote the achievable runout feature by feature.

Q: What materials do you routinely turn and mill?

The full list from aluminum to Inconel 718 and P550 non-magnetic alloys — see Materials →.

Q: Do you provide material certificates and inspection reports?

With every order — mill certs with heat-number traceability and dimensional reports from our in-house metrology.
