Custom CNC machining services add accurate features to formed metal parts. Our factory in Hebei, China, uses CNC equipment for post-forming work. We add holes, slots, threads, and finished surfaces per your drawing. CNC machining closes the gap between a formed part and a final product. Projects scale from prototypes to production runs.
What Is Custom CNC Machining?
CNC machining uses computer-controlled tools to remove material. It follows your drawing with high repeatability. The process adds features that forming alone cannot produce.
- CNC milling — flat faces, slots, and pockets
- Drilling & tapping — accurate holes and threads
- Threading — internal and external threads per spec
- Post-forming features — work after stamping, bending, or laser cutting
- Finished surfaces — dimensional accuracy where it matters
CNC Machining Capabilities & Equipment
| Capability | Equipment | Capacity |
|---|---|---|
| CNC milling | CNC machining centers | Faces, slots, pockets and contours |
| CNC drilling | CNC drilling machines | Accurate hole patterns per drawing |
| Tapping & threading | CNC tapping machines | Internal and external threads |
| Part envelope | Standard worktables | Small to medium metal parts |
| Dimensional inspection | Gauges and measuring tools | Critical features checked per drawing |
| Secondary operations | Presses, press brakes, welders | Cutting, bending and welding in-house |
CNC machining is one step in our full production chain. We also run stamping, laser cutting, bending, and welding in-house.🔧Click here to view our complete list of equipment.→

Real Project Result
A representative project from our production history—over 70,000 different types of custom metal parts delivered to date:
CNC-machined parts for a burner assembly
A heating equipment maker needed machined parts for a burner assembly. A rod, a mounting plate, and threaded features had to fit formed sheet metal parts. CNC machining delivered the parts to spec, ready for assembly.
- Part: CNC-machined rod and mounting components for a burner, with laser-cut holes on the base
- Process: laser cutting (base holes) → CNC machining → threading → surface finishing → assembly
- Key challenge: accurate threads and hole patterns, plus clean laser-cut edges
- Our solution: CNC programs verified against the drawing, plus in-process checks
- Production: 500 pcs per order
- Quality result: threads, hole positions, and cut edges verified per drawing

Frequently Asked Questions
Can CNC machining be combined with sheet metal forming?
Yes. We machine features after stamping, bending, or laser cutting. One supplier covers the full process.
Which materials can you machine?
Stainless steel, aluminum, carbon steel, brass, and copper. Material grade follows your drawing.
Can you machine prototypes?
Yes. CNC needs no dedicated tooling. We machine prototypes directly from your drawing.
Do you check machined dimensions?
Yes. We check critical features in process and before shipping. Reports are available on request.
