Custom CNC Machining · Tongyong Industries
Tongyong Industries provides custom CNC machining services for global B2B projects, producing precision metal parts from prototype manufacturing through repeat production. We machine milled, turned, 5-axis and wire EDM parts to confirmed drawings, with DFM review available before quoting.

Great products often start as one prototype on a startup's bench. Low quantities are not a problem here — we welcome early-stage teams and growing brands and provide engineering support throughout development. As volumes rise, confirmed processes help support a smoother transition to repeat production. Our goal is to support every stage of your product development.
Even a single part is welcome — prove the design first.
Tested parts and DFM feedback that de-risk the next step.
Small batches that confirm a stable, repeatable process.
Repeatable production with consistent quality and agreed delivery schedules.
Integrated support for CNC milling, turning, 5-axis machining, micromachining and EDM—from prototypes to repeat production.
3-axis milling for enclosures, brackets, plates and heat sinks, held to tight dimensional and surface tolerances. Ideal for housings and structural parts.
Precision turned shafts, sleeves, pins, threads and connectors with controlled diameter, length and surface finish — the foundation for transmission and fastening parts.
Multi-face, multi-angle geometries machined in a single setup — complex contours with fewer fixtures, fewer re-clamps and higher repeatability across batches.
High-precision CNC micromachining for miniature metal parts requiring fine features and tight tolerances.
Sharp corners, narrow slots, hardened metals and complex profiles that conventional cutting can't reach — accurate contours with low distortion.
Coordinate anodizing, polishing, bead blasting and other finishing processes to improve part appearance, surface performance and functional requirements.
01 - Custom
Every part is made to your drawing — your material, tolerance, finish and quantity. No catalogue limits and no forced standard parts.
02 - Quality
Material checks, in-process inspection and final dimensional verification help confirm parts meet the agreed requirements.
03 - Support
Questions are addressed early, requirements stay aligned, and project details are tracked from drawing review through delivery.
Not sure which alloy fits? Tell us the application and our engineers recommend a grade during DFM review, balancing strength, weight, corrosion resistance, machinability and cost.
| Preview | Finish | What it does |
|---|---|---|
|
As-machined | The default finish straight off the machine, typically Ra 1.6–3.2 µm with light visible tool marks. |
|
Anodizing | Type II and hard-coat anodizing create a protective oxide layer on aluminium for corrosion resistance, wear resistance and color. |
|
Polishing | Mechanical polishing reduces roughness to a bright, smooth or mirror surface for cosmetic and high-spec parts. |
|
Bead / sand blasting | Blasting media give a uniform matte texture, removing tool marks and evening the surface before or after coating. |
|
Tumbling / deburring | Vibratory tumbling deburrs and smooths small parts in bulk, rounding sharp edges and evening the surface. |
Our engineers analyze your drawing for process and feasibility, then confirm the machining plan and quote.
Parts are machined to the confirmed plan, with the whole process monitored for accuracy and efficiency.
Finished parts are checked across multiple dimensions to confirm size, finish and performance meet spec.
Approved parts are packed and shipped with tracking, so your order reaches you on time and intact.

Why a single blanket tolerance is the wrong way to spec a part, and how confirming critical dimensions at DFM keeps quality high and cost sensible.
Common questions
A 3D model (STEP or IGES) is ideal, along with a 2D drawing (PDF or DWG) for critical dimensions, tolerances and finish. A sketch with a short description is enough to start the conversation.
Yes — we welcome orders starting from 1 piece, and support early-stage teams through prototype validation before scaling to production. There's no minimum order quantity requirement to get started.
Manufacturing capabilities are based in China, coordinated through Tongyong Industries as the international business and contracting entity, with over 20 years of manufacturing experience.
Yes, tight tolerance machining is part of our standard capability — the achievable tolerance depends on part geometry, material, and process. Share your drawing's critical dimensions and we'll confirm what's realistic, including for parts requiring 5-axis simultaneous machining.
We offer CNC milling, turning, 5-axis machining, micromachining, and wire/sinker EDM. For complex geometries requiring simultaneous multi-face access, our 5-axis capability reduces re-fixturing and improves repeatability across batches.
No — please specify the exact grade (such as 6061-T6 or 7075-T6 aluminum) rather than just the material family, since different grades affect machinability, strength, and finish compatibility. If you're unsure which grade fits your application, our engineers can recommend one during DFM review.
Yes, our engineering team reviews your drawing for manufacturability before quoting, flagging issues like thin walls, tight tolerances that aren't functionally necessary, or features that add cost without adding value. This helps catch problems before they become expensive to fix.
