Custom CNC Machined Carbon Fiber Frame Plate

FlexiTurn CNC-routes flat CFRP frame plates with X-brace cutouts, slotted openings and mounting holes from 3K twill-weave quasi-isotropic epoxy laminate for drone platforms, gimbal assemblies and robotic structures.

FlexiTurn controls thin-web delamination, slot wall fiber fraying and hole-to-cutout positioning with PCD cutters, vacuum fixturing over phenolic backing board and documented feed-and-speed parameters, minimizing bottom-side splintering and hole drift while delivering controlled edge quality and repeatable dimensional accuracy from prototype to medium-volume production.

Machining Process & Capabilities

FlexiTurn runs all CFRP operations in-house. Tooling geometry, spindle speed and feed per tooth are locked to woven carbon fiber composite.

• 3-Axis CNC Routing & Contouring: Outer frame profile, X-brace internal cutouts and slotted adjustment openings routed from 3K twill CFRP sheet under vacuum table over phenolic backing board. PCD compression cutters control top- and bottom-side splintering, particularly at thin web edges. Cosmetic face routed face-down under protective film.
• Precision Drilling: Perimeter mounting holes and central fastener holes drilled with carbide step drills at controlled feed. Heat-set inserts (M3/M4 standard) pressed post-routing; direct tapping of CFRP not offered.
• Edge Finishing: Deburred without rounding bearing surfaces. Edge sealing available on request.
• Laminate Sourcing: 3K twill quasi-isotropic CFRP in stock. Plain-weave CFRP, G10/FR4 and phenolic sheet on request. Custom layup, autoclave-cured and molded parts outside our scope.

Materials & Dimensional

Specifications Standard material: 3K twill quasi-isotropic CFRP, black epoxy matrix

On request: 3K plain-weave CFRP, G10/FR4 fiberglass, phenolic sheet

Standard thicknesses: 1.0 / 1.5 / 2.0 / 3.0 / 4.0 / 5.0 mm

Contour tolerance: ±0.10 mm on outer profile, parts ≤ 300 mm

Hole-pattern location: ±0.05 mm between perimeter holes and central datum, panels ≤ 300 mm

Thin-web edge quality: No visible interlayer separation on web edges; micro-splintering within industry limits

Surface finish: Raw 3K twill weave preserved on cosmetic face

Max panel: 600 × 600 mm off-the-shelf sheet; 600 × 400 mm per single vacuum-fixtured setup

Why Choose FlexiTurn

• PCD cutters, not worn carbide — consistent edge geometry across production runs; critical for thin X-brace webs where delamination propagates fastest.
• Vacuum hold-down + phenolic backing board — clean top- and bottom-side edges on internal cutouts; thin webs route without chip-out.
• Cosmetic-face protection — as-supplied 3K weave preserved face-down under film; no secondary sanding.
• Heat-set inserts by default — eliminates tapped-hole thread stripping.
• Thin-web routing experience — X-brace and lattice cutouts require controlled feed at narrow neck transitions; generic shops break webs or delaminate at corners.
• We say what we don’t do — no custom layup, autoclave structures, flight-certified parts or molded carbon. 
• Prototypes to medium volume — no tooling cost at low volume; optimized panel nesting at production.
• Single-source across materials — CFRP frame plates plus machined metal adapters, standoffs and brackets.

How to Proceed

• Submit 2D (PDF/DWG) or 3D (STEP/IGES) CAD files, laminate type, thickness, hole-pattern datum, tolerances, cosmetic face, quantity and environment.
• Receive CFRP-specific DFM review and factory-direct quote within 24 hours.
• Prototype plates shipped with dimensional inspection report and material certification.
• Volume production with locked routing parameters and scheduled in-process hole-pattern verification.
• Global shipping, edge-protective packaging.
