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.

Composite dust requires safe handling and housekeeping. Tell us your site EHS rules; we align packaging and cleaning accordingly.

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.
