Precision CNC Fiberglass Machining: Your Complete Guide

What is CNC Fiberglass Machining?

CNC fiberglass machining uses computer-controlled cutting tools to shape fiberglass materials with extreme precision. These machines follow digital designs to create parts that meet exact specifications.

Materials We Work With

Our Advanced Equipment

Our facility features state-of-the-art 5-axis CNC routers that can create complex shapes with outstanding precision. These machines work with sheets up to 120″ x 60″ and can handle material thickness from 0.1″ to 4″.

Key Features:

• ±0.005″ tolerance for critical components
• Vacuum table fixturing for perfect stability
• HEPA filtration dust suppression system
• PCD-coated cutting bits that reduce delamination

Manufacturing Processes

At Istar Machining, we use advanced techniques to ensure the best results:

5-Axis CNC Routing

Our 5-axis machining capabilities allow us to create complex contours and shapes that would be impossible with standard equipment. This technology is perfect for:

• Complex curved surfaces
• Undercuts and details
• Parts with multiple angles

Dust Suppression Systems

Working with fiberglass requires special care. Our OSHA-compliant HEPA filtration system:

• Removes harmful dust
• Keeps the workspace clean
• Protects both workers and parts
• Meets all safety standards

Tooling Solutions

We use special tools designed for composite materials:

• PCD-coated bits for clean cuts
• Diamond abrasive tools for smooth finishes
• Specialized bits that prevent delamination

Benefits of CNC Fiberglass Machining

1. Precision Engineering – Achieve tolerances down to ±0.005″
2. Material Efficiency – Minimize waste with optimized cutting paths
3. Design Freedom – Create complex shapes impossible with other methods
4. Consistency – Every part meets exact specifications
5. Cost Effectiveness – Competitive prices, especially for small to medium runs
