Custom Carbon Fiber Cross Beam Manufacturer

Viga transversal de fibra de carbono personalizada

Vigas de pórtico multicelulares leves para máquinas de alta velocidade e alta precisão

ANT COMPOSITES fabrica vigas transversais de fibra de carbono personalizadas para máquinas CNC, equipamento de corte a laser, sistemas de distribuição, automação industrial e plataformas de movimento de precisão.

Nossas vigas mecânicas combinam uma estrutura multicelular fechada com reforço de fibra de carbono específico para cada aplicação. Em comparação com vigas transversais metálicas convencionais, um projeto otimizado de CFRP pode reduzir a massa móvel em mais de 40% mantendo a rigidez e a estabilidade dimensional exigidas por equipamentos de alta velocidade.

The Problem With Traditional Beams

Aço

Rigid but Heavy

High mass increases inertia and drive load.

Alumínio

Light but Less Stable

Lower stiffiness leads to vibration and accuracy loss.

Fibra de Carbono

Light + Stiff + Estável

Superiour stiffness-to-weight for manximum performance

Engineered from the Inside Out

Closed Box Shell

High-strength carbon fiber skins deliver torsional rigidity and impact resistance.

Internal Reinforcing Webs

Optimized web layout controls shear and prevents local buckling.

Multi-Cell Structure

Increases stiffness and stability while reducing mass.

Precision Mounting Face

CNC-machined surfaces ensure perfect alignment and repeatability.

Built for Dynamic Machine Performance

Faster Response

Lower inertia for higher acceleration and throughput.

Stable Precision

High stiffness maintains accuracy at high speed.

Lower Thermal Drift

Carbon fiber’s low CTE minimizes thermal expansion.

Reduced Drive Load

Lower mass reduces wear and extends component life.

Perguntas frequentes

1. How much weight can a carbon fiber cross beam reduce?

Our general positioning is more than 40% weight reduction compared with conventional metal beams. Actual results depend on the original beam and final CFRP design. Individual customer projects have achieved reductions above 64% e 76%.

2. Can the beam support 6G acceleration?

The CFB-A17395-S2 reference configuration has supported a qualified 6G application. This does not mean every beam is automatically rated for 6G. Beam length, carga útil, connections and the complete machine must be evaluated.

3. What straightness can you achieve?

Qualified beam designs can achieve straightness down to 0.01 mm/m. The achievable value depends on length, mounting surfaces and inspection requirements.

4. What is the maximum available length?

Selected 4.5-meter specifications are available, and production lengths above 7.5 meters can be evaluated for volume projects.

5. Can you machine linear-guide mounting surfaces?

Sim. Surface machining, guide holes, positioning holes and insert installation can be discussed. Required flatness, straightness and parallelism must be stated on the drawing.

6. Can you replace our current aluminum or steel beam?

Send us the current drawing, material, weight and working conditions. We will review the technical feasibility and potential machine-level benefits.
