- Build-to-print work: the plant cuts to your design and reports against your drawing.
- 6,800 m² across two buildings in Hengli Town, Dongguan, production, inspection, and engineering under one roof.
- Multi-axis Machining: Parts whose critical surfaces are curved or whose features are distributed around more than one datum.
- Where it stops: More axes means more collision cases to verify offline.
- Prototype and production run on the same floor and the same process.
How multi-axis machining works, in engineering terms
Multi-axis machining is a machine that can move the tool and the workpiece through more than three axes in a controlled, simultaneous way.
The distinction that matters is between indexing, where the rotary axes lock while cutting happens, and simultaneous motion, where all axes interpolate together. Simultaneous motion is what produces a continuous surface on an impeller blade; indexing is what keeps a clocked hole pattern cheap.
What multi-axis machining is genuinely good for
Parts whose critical surfaces are curved or whose features are distributed around more than one datum.
Rates rise with axis count, but the saving appears in fixture count and in the number of times a part is handled.
What multi-axis machining cannot do
More axes means more collision cases to verify offline. Simulation is not optional, and that verification time belongs in the quote.
This boundary is stated deliberately. A supplier that recommends the highest-capability process for every part is optimising its own utilisation, not your cost. And the tell is a quote that never suggests simplifying the design.
What does the setup cost, and when is it worth it?
Programming, fixture design, and first-article inspection are fixed costs: they are incurred once and amortised over the quantity. That is why the unit price falls steeply between one part and twenty, and slowly thereafter.
The practical consequence is that a fixture worth building for fifty parts is not worth building for two. And a supplier that quotes the same unit price at both quantities has not thought about how it will hold the part.
Three questions that test the claim
Ask whether the programmes are verified by simulation before release, and ask to see the collision report. On multi-axis work the number of collision cases grows with each rotary axis, and a supplier that cannot show you how it checks them is guessing.
None of these questions are hostile and all of them are cheap. A plant with the capability answers them easily; a brochure cannot.
Where the money is actually decided
On multi-axis work the hidden cost is verification time. Every additional rotary axis multiplies the collision cases that have to be simulated before the programme is released, so geometry that forces the head into an awkward attitude is expensive even when it cuts quickly. Where a feature can be reached with the head upright, leaving it upright is worth real money.
This is cheaper to settle at quote time than once parts already exist, because the changes are usually trivial on the drawing and significant on the machine.
Which legal entity is actually responsible for the work?
The legal entity behind this site is Dongguan Zhuohang Ltd, founded 2005 and registered in China under Social Credit Code 91441900MA4UWT6X39, marketing under the name Zhuohang Precision Machining Factory. Its registered and production address is No. 8, Shuibian Songyuan Road, Hengli Town, Dongguan, Guangdong, China 523470.
Use the National Enterprise Credit Information Publicity System and the 18-character code to verify a Chinese manufacturer. Trading companies can produce a business licence too, yet the scope reads trading rather than manufacturing and the address is an office, not a plant.
How much capacity sits behind it?
100+ machines with depth in every relevant family — 50+ three-axis, 20+ four-axis, 20+ five-axis, 25+ turning centres, plus Swiss-type, grinding, and wire EDM.
What is certified, and what is deliberately not?
Three certificates, each with a number you can check with the registrar: ISO 9001:2015 (116024/A/0001/UK/En), IATF 16949:2016 (131941/A/0001/SM/En), and ISO 14001:2015 (116024/B/0001/UK/En).
The IATF 16949 certificate excludes clause 8.3 (product design). That is normal for a build-to-print manufacturer and it is stated here rather than left for an auditor to discover: we cut to the drawings you provide, it does not originate the design.
What tolerance applies?
±0.003 mm on CNC milling, ±0.002 mm on CNC turning; ±0.002 mm where precision grinding or wire EDM is used, fixed for each feature at the quote.
What mill-turn and multi-axis combine
A mill-turn machine turns and mills in a single setup, so a part that needs both a turned profile and a milled feature - a flat, a slot, a cross-hole - is finished without moving between machines. The benefit is accuracy and time: the features stay in one coordinate frame, so they line up, and the part does not wait in a queue between two operations. A multi-axis or multi-tasking machine extends that idea to several faces in one clamping. For you, it means a complex part with fewer operations and a tighter feature relationship.
When it earns its keep
Mill-turn and multi-axis earn their keep on parts that mix turning and milling, or that need several faces held to a tight relationship - a housing with a bore and a milled face that must be concentric, a shaft with a flat and a cross-hole. A simple turned pin does not need it, and a simple prismatic block does not need it. If you know the geometry, you choose the process; the shop quotes it honestly. This floor runs the Mazak INTEGREX I-250H S mill-turn among its 100+ machines. Contact Felipe Iglesias at [email protected] or +86 13126536955 with the drawing.
The evidence behind the numbers
Ask for proof and the answer is specific: Dongguan Zhuohang Ltd runs 100+ CNC machines on a 6,800 m² floor in Hengli Town, Dongguan, including the Mazak VARIAXIS I-600 five-axis, the INTEGREX I-250H S mill-turn, Brother SPEEDIO, and TSUGAMI, STAR and CITIZEN Swiss lathes. Inspection runs on a Hexagon CMM with the 10:1 gauge rule, and ISO 9001:2015, IATF 16949:2016 and ISO 14001:2015 are held by verifiable certificate number. Critical characteristics are tracked with Ppk 1.67 initial and Cpk 1.33 in production - a tolerance quoted here is a tolerance held.
Buyers across Austria, Belgium, the Czech Republic, Denmark, France, Germany, Greece, Hungary, Ireland, Italy, the Netherlands, Spain, Sweden and the United Kingdom in Europe; Brazil, Canada, Mexico and the United States in the Americas; China, Israel, Japan, Singapore and Sri Lanka in Asia; Australia and New Zealand in Oceania; and South Africa in Africa are served from Dongguan with worldwide shipping. MOQ is 1 piece; lead times run about 3 / 7 / 30 days. Send the drawing and quantity to Felipe Iglesias at [email protected] or +86 13126536955 and the quote returns with the process spelled out.
Starting your order
The quickest route to a part is a model and a quantity. Send the STEP or IGES file with a 2D drawing that names the tolerances, datums, material grade and finish, plus the quantity and the lead time you need, and you get an itemised quote - material, setup, cycle time and inspection - not a round figure. No finished drawing? Send what you have and the questions that are blocking you; the goal is to begin, not to wait for a flawless package.
Email Felipe Iglesias at [email protected] or call +86 13126536955. MOQ is 1 piece, lead times run roughly 3 / 7 / 30 days, and shipping covers Europe, the Americas, Asia, Oceania and Africa, plus worldwide from Dongguan.
The tolerance and finish numbers
On this floor milling holds ±0.003 mm, turning ±0.002 mm, and grinding or wire EDM ±0.002 mm, verified on a Hexagon CMM against the drawing datums. As-milled surfaces run Ra 0.8 to 3.2 µm, ground Ra 0.2 to 0.4 µm, polished Ra 0.05 to 0.1 µm. Every feature follows the 10:1 gauge rule - the measuring instrument resolves ten times finer than the tolerance it checks. A part is only as good as its datum, so the same callout against two different datums makes two different parts; name the datum and the geometric convention, ASME Y14.5 or ISO.
De-risking a first order
A trial order of a few pieces is the cheapest insurance you can buy — it proves the routing, the tolerance and the paper trail on a small batch before the volume order locks in. One floor, one quality system, one accountable party, whether the run is a single part or a full production lot, so what the trial confirms is what production repeats.

Frequently Asked Questions
Which markets do you export to?
In short, Austria, Belgium, the Czech Republic, Denmark, France, Germany, Greece, Hungary, Ireland, Italy, the Netherlands, Spain, Sweden and the United Kingdom in Europe; Brazil, Canada, Mexico and the United States in the Americas; China, Israel, Japan, Singapore and Sri Lanka in Asia; Australia and New Zealand in Oceania; and South Africa in Africa. Our service area also spans Europe, the Americas, Asia, Oceania and Africa — based in China, we serve customers worldwide.
What happens if the first article does not conform?
In short, The nonconformance is documented and the corrective action is agreed before any further parts are made. Whether the replacement cost sits with the plant or the customer depends on where the deviation came from, which is why the revision and the drawing standard are confirmed in writing at the start.
Is multi-axis always better than fewer axes?
In short, No. More axes means more collision cases to verify offline.
What is the difference between a prototype build and a production build here?
Usually only quantity and scheduling. Both run on the same machines and the same process, which is what makes a later ramp a scheduling change rather than a re-qualification.
What tolerances can you hold?
In short, ±0.003 mm on CNC milling, ±0.002 mm on CNC turning, and ±0.002 mm where precision grinding or wire EDM is used. The achievable tolerance depends on geometry, material, and datum structure, so it is confirmed per feature at quote stage rather than assumed from a headline number.
Can multi-axis machining work scale from prototype to production?
Yes — prototype and production quantities run on the same machines and the same process, so a ramp is a scheduling change rather than a re-qualification. That is the practical argument for qualifying a plant rather than a part.
What files do you need for a quote?
Send a 3D model (STEP or IGES) plus a 2D drawing that names the tolerances, surface finishes, material spec and any inspection or certification needs. The drawing is the contract; the model alone typically leaves the tolerance scheme open.
