3 Axis CNC Machining Factory

Is this a factory or a trading company?

The shortest answer is in the ownership: Dongguan Zhuohang Ltd owns and operates the facility directly. It is not a broker quoting on behalf of someone else's machines. The evidence you can check independently is in the registration number and the machine list.

The company was founded in 2005 and has operated under the names Dongguan Zhuohang Ltd and Zhuohang Precision Machining Factory at various times; the current legal name is Dongguan Zhuohang Ltd and the marketing brand is Zhuohang Precision Machining Factory. That name history is public and verifiable — ask for the business registration profile if you want the full record.

The practical difference between a factory and a trading company comes down to one test that takes a single email to run: ask who owns the machines that will cut your part. A factory owns and operates them, so it can name models, counts, work envelopes and the operators behind them. A trading company does not, so it dodges the machine list and talks instead about "our partners" or "our network." When you buy from the factory, there is no middle margin and no one to blame but the shop that actually held the tolerance, which is exactly the accountability you want on a precision part.

What is the legal entity and registration number?

Field	Value
Legal name	Dongguan Zhuohang Ltd
Marketing brand	Zhuohang Precision Machining Factory
Registration / VAT number	91441900MA4UWT6X39
Founded	2005
Location	Hengli Town, Dongguan, Guangdong, China

For any overseas order, these are the facts that go on your purchase order and your compliance paperwork. A registration number you can look up is the difference between a real manufacturer and a website that could disappear tomorrow.

What does the facility actually contain?

The scale is what keeps a machining program consistent from prototype to production. Our floor covers 6,800 m² with 100+ employees and 100+ production machines.

Resource	Count	Work envelope / notes
3-axis milling	50+ centers	Up to 1300 × 700 × 600 mm
4-axis milling	20+ centers	Multi-face parts, angled holes
5-axis milling	20+ centers	Complex wrapped geometry
CNC turning	25+ lathes	Up to Ø720 × 1280 mm
Precision grinding	7+ machines	Surface / centerless / cylindrical, ±0.002 mm
Wire EDM	Dedicated cells	Sharp internal corners, hardened material
Inspection	20+ instruments	Hexagon CMMs, vision, XRF, hardness, roughness

The counts add up to a plant that can hold a program from a single prototype to a production batch without farming the work out. The 3-axis milling banks handle the flat and boxy work; the turning floor handles the round work up to Ø720 × 1280 mm; the grinding department brings bearing seats and roundness-critical surfaces down to ±0.002 mm; and the inspection bench closes the loop on every step. A buyer reading this table should see a complete chain, not a list of machines in isolation, that completeness is what keeps a multi-process part under one roof and one point of accountability.

Where is the factory located?

The facility is in Hengli Town, a manufacturing district of Dongguan, Guangdong — a region with dense machining supply chains for materials, heat treatment and surface finishing. The address is No. 8, Shuibian Songyuan Road, Hengli Town, Dongguan, Guangdong, China 523470.

Being in Dongguan is a practical advantage, not just a label: raw material, tooling and finishing partners are close by, which shortens lead time and keeps the whole program under one accountable chain.

Which certifications does the factory hold?

Certifications are your cheapest pre-audit. The factory holds three, each with a number you can verify with the registrar:

Standard	Certificate number	Scope
ISO 9001:2015	116024/A/0001/UK/En	Machining of metal parts
IATF 16949:2016	131941/A/0001/SM/En	Manufacture of CNC metal machining parts (excludes product design, Clause 8.3)
ISO 14001:2015	116024/B/0001/UK/En	Environmental management related to machining of metal parts

Three certificates, each with a scope and a number, tell a buyer more than a wall of logos ever could. ISO 9001 confirms a documented quality management system; IATF 16949 confirms the automotive-grade process control — SPC, control plans, PFMEA and traceability — that a regulated buyer expects; ISO 14001 confirms the environmental management runs alongside the quality system. Read them together with the scope lines, and you get a picture of what the factory is actually audited against, not just what its marketing page claims. A factory that hands over all three numbers without hesitation is a factory that has already been through the audit; one that hesitates is telling you something by its silence.

Honest scope note: IATF 16949 excludes product design under Clause 8.3. We are a build-to-print manufacturer — read the scope line on any supplier's certificate before you assume they own design responsibility.

What protects your delivery date — the re-routing logic

Depth in a machine family is not a vanity number; it is the mechanism that protects a delivery date. When a machine is pulled for service or a single job overruns, a floor with one machine in the family has nowhere to send the rest of the queue — the work waits. A floor with 50+ three-axis centres can move a stalled job onto a free machine in the same family with the same fixture and the same program, so a maintenance event becomes invisible to the schedule rather than a missed date.

The same logic applies across families. A turned blank that needs a milled feature does not leave the building, because the milling banks sit in the same plant. A part that needs a ground seat moves to the grinding department in the same aisle. The fewer external handoffs a part makes, the fewer freight legs, the fewer inspection gaps, and the fewer parties who can each blame the last one. When you ask a supplier about capacity, the useful question is not "how many machines" but "how many in the family my part uses, and what happens to my slot when one of them stops" — the answer tells you whether the date you were given is a schedule or a hope.

What should you check on a factory visit?

A visit is the strongest due-diligence check available, and it works best when you know what to look for. Walk the floor with this short checklist.

Visitors are welcome by appointment. Contact [email protected] to schedule, and we will walk you through the floor, the inspection bench and the quality system in person.

Which machine brands and models run the floor?

A machine list is the fastest way to tell a factory from a trading desk, and the brands on the floor matter because they set the accuracy and reliability ceiling of everything that leaves it. The representative families here include Brother SPEEDIO and Mazak vertical machining centers for 3-axis milling, Mazak multi-tasking and 5-axis centers for complex work, and Citizen, Star and Tsugami Swiss-type lathes for precision turning, with Sodick for high-accuracy work. Grinding runs on dedicated surface, centerless and cylindrical machines.

The point of naming them is not brand prestige — it is verifiability. You can check a Brother or Mazak model against the vendor's datasheet and confirm the work envelope and spindle the shop claims. That check is what separates a machine list from a marketing photo. When a shop names models and counts you can verify, you are looking at a factory; when it shows a stock image of a machine it may not own, you are looking at something else.

Process	Representative brands	Why it matters to the buyer
3-axis milling	Brother SPEEDIO, Mazak VMC	Fast, rigid prismatic work on brackets, plates and housings
Multi-tasking / 5-axis	Mazak	Complex and wrapped geometry in fewer setups
Swiss-type turning	Citizen, Star, Tsugami	Long, slender turned parts with tight roundness
Precision / EDM work	Sodick	High-accuracy features that milling cannot reach

Who actually runs the factory?

A building full of machines is not a factory until people run a documented process through it. The organization behind the floor is what turns the equipment into repeatable output, and it is worth your attention the same way the machine list is. The facility runs with 100+ people across machining, programming, inspection and quality, plus the engineering support that does DFM reviews and quoting.

What matters to you is not the headcount number but the functions behind it. A shop needs programmers who read a drawing and see the setups before the first cut, machinists who run the part to a control plan, inspectors who measure against the print rather than against hope, and a quality team that documents it all. When you correspond with a supplier and the same person answers quoting, quality and logistics questions, that is a clue the "factory" is a thin front. A real factory routes each question to a person whose job it is.

How does the Dongguan location shorten the program?

The facility sits in Hengli Town, Dongguan, Guangdong, and the location is a practical advantage, not a talking point. Dongguan and the surrounding Pearl River Delta hold a dense chain of raw material suppliers, heat treaters, anodizers and tooling shops, which means most of the secondary steps in a machining program are minutes or hours away rather than days.

That proximity shows up in two places you can feel. First, lead time: when a part needs anodizing or stress relief, the handoff is short, and the whole program stays under one accountable chain. Second, cost and risk: the less a part travels between operations, the fewer freight legs and handling marks it picks up. A buyer sourcing from a region with a dense machining supply chain is buying shorter loops, not just a cheaper machine-hour.

The address is No. 8, Shuibian Songyuan Road, Hengli Town, Dongguan, Guangdong, China 523470, and the registration number 91441900MA4UWT6X39 ties that physical location to a legal entity you can look up — the two facts that anchor a factory claim to something real.

How does the factory scale from prototype to production?

The hardest moment in a machining program is the handoff from the prototype you validated to the production run you committed to, and it is exactly where a well-organized factory shows its value. The key is that the prototype and the production part are made the same way: same machine families, same fixtures, same programs and the same tolerances.

Because the floor carries 100+ machines across 3-axis, 4-axis and 5-axis milling, turning and grinding, a part does not jump to a different vendor or a different process when volume rises — it runs on more machines of the same kind, with the process already proven. The 1 piece MOQ is what makes that bridge real: you validate one, then scale to a thousand, and the part you validate is the process you scale. That continuity is worth more than any single machine spec, because it removes the most common source of production surprises.

What should you verify before a first order?

Beyond a visit, a handful of documents close the loop on a factory claim, and they are all things you can request in one email before placing a first order.

• Business registration profile — confirms the legal entity, the registration number and the operating history behind the brand.
• The machine list — models and counts you can check against vendor datasheets.
• Certificate numbers — ISO 9001, IATF 16949 and ISO 14001, verifiable with the registrar.
• A sample inspection report — a CMM or SPC report from a real job, so the tolerance claim has evidence behind it.
• A named contact — one person who owns your program end to end, reachable in your language.

None of these is hard for a real factory to produce, and all of them are awkward for a front to fake. Together they turn "trust me" into "verify me", which is the whole point of the due-diligence exercise this page is built around.

Use this to triage a supplier before you send a drawing. If a supplier stalls on more than one item, treat the "factory" claim as unproven.
