Precision machining, engineered with your drawing
From a single prototype to a full production run, our CNC cell delivers consistent, dimensionally stable parts. A dedicated project engineer reviews your drawing, returns DFM feedback within 24 hours and stays with the job through first article, production and delivery.
Machines, tooling and inspection are all in-house, so prototypes and production parts come from one certified quality system rather than a chain of vendors.
What our CNC cell covers
Four in-house capabilities, one accountable project engineer.
CNC Turning
Precision lathe work for cylindrical parts, threads and concentric features.
Surface Finishing
Anodizing, plating, powder coating, bead blasting and custom finishes.
Quality Inspection
CMM inspection, first article reports and full dimensional documentation.
The machines behind the parts
Our own fleet - the same equipment your prototypes and production runs run on.

How a CNC job runs
A fixed path from drawing review to a measured, shipped part.
-
01
Drawing review & DFM
We check tolerances, datums and tooling access, and come back with a manufacturability note within 24 hours.
-
02
Prototype
Machined sample parts in 3-5 days so you can validate fit, function and finish before committing.
-
03
Production
Approved machines, fixtures and a documented process - monitored with weekly progress reports.
-
04
Inspection & delivery
CMM or dimensional report, first article documentation on request, shipped worldwide.
Why teams outsource CNC to BAOLAIHUA
Fast delivery
Prototype parts from 2-3 days and standard lead times of 3-5 days.
On-time delivery
95.4% of orders ship complete and on time, with weekly status reports.
Precision engineering
3/4/5-axis machines and CMM verification on every production batch.
Material expertise
From aluminium to PEEK, with tooling and process matched to the material.
Low to high volume
One part for validation or a scheduled repeat order - same process.
Engineering partnership
Feasibility advice before the quote, not a price list after it.
CNC machining questions
The questions engineers ask us most often - answered without marketing.
What tolerance can you hold on a machined part?
Critical features to +/-0.005 mm; a standard machined tolerance is +/-0.05 mm. We confirm what is realistic per feature after DFM review.
How fast can I get prototype parts?
Machined prototypes typically ship in 3-5 days. Bridge or production tooling adds 4-6 weeks depending on complexity.
Which materials do you machine?
Aluminium 6061/7075, stainless 304/316L, carbon steel, brass, copper, titanium, ABS, POM, PEEK and nylon. See our material guide for the full list.
Do you supply inspection reports?
Yes - CMM or conventional dimensional reports, first article inspection and material certificates on request.
Can you handle very small quantities?
Yes. Single parts and batches of 1-50 are routine; they are simply priced differently from production runs.
Is my design kept confidential?
Yes. We sign an NDA on request and do not publish or resell customer geometry.
