Composite & carbon plate machining
Fiber-reinforced plates and laminates can save weight—if tooling paths respect fiber direction and avoid delamination. We focus on contoured trimming, pocketing, and fixture-ready blanks, with candid talk about edge sealing and inspection for your industry.
Tooling for fibers
Diamond-coated or PCD strategies where dust control and edge quality matter.
Delamination control
Feeds/plunges tuned to reduce peel-up at exits—especially on thin sandwich panels.
Practical tolerances
Composites move with temperature and moisture—your tolerance stack should include it.
Why buyers work with us on this process
Clear scope, documented checks, and quotes aligned with how we actually run production.
High stiffness-to-weight
Useful for drones, robotics, and lightweight tooling.
Corrosion resistance
No rust—watch galvanic couples when bolting to aluminum or steel.
Tailored directionality
Layup orientation drives strength—note fiber direction on critical features.
Cost-aware prototyping
CNC from sheet/plate before committing to molded preforms for some programs.
Edge sealing options
Resin coat or trim strategies to protect exposed fibers in service.
Partner processes
When you need autoclave or molded blanks, we align machining to supplier tolerances.
What we commonly machine
Not all “carbon” is the same—prepreg, rolled, or forged plates behave differently in the cut.
| Type | Typical use | Notes |
|---|---|---|
| CFRP plate / sheet | Brackets, panels, UAV structures | Watch fiber pull-out on exits |
| GFRP (glass) | Electrical grade laminates, insulation | Abrasive on tools—dust control |
| Sandwich panels | Light stiff panels | Avoid crushing core—vacuum fixtures |
We may request a sample scrap cut to validate edge quality on new laminates.
Typical tolerance bands
Composite stacks vary—first article cut recommended for critical fits.
| Feature | General (mm) | Tighter (mm) |
|---|---|---|
| Dimension | ±0.10 | ±0.05 |
| Hole | ±0.08 | ±0.03 |
| Flatness (per 100 mm) | 0.10 | 0.05 |
Ultra-tight optical fits may need secondary lapping—quoted separately.
Typical end uses
UAV & robotics
Frames, motor mounts, and stiffening plates.
Motorsport / performance
Non-critical cosmetic and bracket parts—specify crash or load cases if relevant.
Industrial automation
Light tooling, guarding, and end-effector parts.
Electronics hardware
RF-transparent or structural shrouds when drawings allow laminates.
Finishing & post-processing
We coordinate common finishes through vetted partners when your drawing calls for them—lead time and cost are quoted together with fabrication.
| Option | What it does | Common use |
|---|---|---|
| Edge seal / resin coat | Protects exposed fibers from moisture wicking. | Marine / outdoor |
| Clear coat / paint | UV and cosmetic protection. | Customer-visible parts |
| Micro-sanding | Blend minor fray for class-A adjacent assemblies. | Show parts |
| Laser mark | Low-power settings to avoid fiber damage. | Traceability |
FAQ
Do you waterjet composites?
We can advise; some layups are better on CNC for edge quality—depends on geometry.
Can you bond inserts?
Often yes—joint design and adhesive spec should be on the drawing.
Do you store material?
Customer-supplied material is common; we’ll verify flatness and moisture before cutting.
