Swiss-type turning
- Ø0.3–32 mm bar, one-pass parts — no re-chucking
- Slender shafts, pins, fittings, threaded bodies
- ±0.01 mm and mirror finishes where it counts
Swiss-type turning · 3/4/5-axis milling · in-house finishing
Complex parts. Prototype to production. No MOQ.
Broad Precision is a CNC machine shop in southern China. We turn and mill complex parts — Swiss-type shafts, 5-axis housings, multi-cavity plates — hold ±0.01 mm where it matters, and finish them under the same roof. Hardware, robotics and industrial teams in the US and EU send us drawings; we send back DFM reviews in 24 hours.

01 · The floor
A real shop floor, not a trading company
This is where your parts run. CNC turning, Swiss-type lathes and machining centers on one floor, with surface finishing downstream — so one purchase order covers the whole part.

02 · Recent parts
Machined here, finished here
A slice of what leaves the floor. Client drawings stay confidential — every case on this site is shared with permission and no client marks.
03 · What we run
Three capabilities, one purchase order
Milling 3·4·5-axis
- Housings, plates, fixtures, multi-cavity work
- 5-axis for complex geometry in fewer setups
- Prototype today, same fixture for production
One-stop finishing
- Anodizing, plating, e-coating, painting, oxide
- Masking, laser marking, sub-assembly
- Parts arrive finished, inspected and packed
04 · The honest part
No ISO 9001 certificate. Here's what you get instead.
We'd rather show you the floor than frame a certificate. Every claim below is something you can verify before you spend a cent on production.
A
First-article inspection report with every part
Dimensional FAI against your drawing, in the box with the shipment. No report, no shipment.
B
Third-party inspection welcome
SGS, BV, TÜV or your own inspector — book them, we'll put the parts on their table.
C
Live video walk-through
See the machines, the floor and your parts being made — a live tour before you commit.
D
NDA signed before your files
Yours or ours, signed and returned before you send a single STEP file.
E
Start with one piece
We'll machine a single part first. Judge the work, then talk batches — not the other way round.
F
Fixed person, fixed answer
You talk to Will directly — the same engineer from quote to delivery, no agent chain.
Inspect the work, not the paperwork — willxu@broadbiz.shop
05 · How an order runs
Drawing in. Parts out. Four steps.
STEP 01
Send your drawing
STEP / IGES / DWG / PDF. NDA first if you prefer — it's a one-day turnaround.
STEP 02
DFM + quote, 24 h
A real engineer reviews manufacturability: what we'd hold in one pass, where a tolerance relax can cut cost.
STEP 03
FAI sample
First article machined and shipped with its inspection report. You measure, we don't just claim.
STEP 04
Batch & repeat
Production with the approved process, finished and packed. Repeat orders skip straight to scheduling.

07 · Questions buyers actually ask
FAQ
Do you have a minimum order quantity?
No. We machine one-off prototypes and support the same part through batch production and repeat orders. Most first orders are 1–10 pieces.
Are you ISO 9001 certified?
Not yet, and we won't pretend otherwise. Instead you get: a first-article inspection report with every part, third-party inspection (SGS/BV/TÜV) welcome, a live video walk-through of our floor, and an NDA signed before you send files. You judge the parts, not the paperwork.
How fast will I get a quote?
Send a STEP, IGES or PDF drawing and you'll have a DFM review and a quote within one business day.
How do you protect my designs?
We sign your NDA — or send ours — before you share files. Drawings are used only for quoting and production, and we can confirm deletion in writing at any time.
What tolerances can you hold?
±0.05 mm as standard, ±0.01 mm on critical features on our Swiss-type lathes and machining centers.
Do you handle surface finishing and shipping?
Yes — anodizing, plating, e-coating and painting are done in-house and with long-term partners under one roof, and we ship worldwide by DHL/FedEx/air/sea with export paperwork handled.

One part or ten thousand. If a feature is better done another way, we'll tell you that too — an honest "no" is part of the service.
