Composite CNC Machining

Composite CNC machining is a special way to shape and cut materials made from two or more different substances mixed together. At Istar Machining, we use high-tech computer-controlled machines to make exact parts from these strong but light materials.

Our team works with many types of composites like carbon fiber, fiberglass, and Kevlar®. These materials are super strong but also very light, which makes them perfect for planes, cars, sports gear, and medical tools.

Why Choose Composite CNC Machining?

Composite materials give you special benefits that regular materials like metal or plastic can’t match:

  • Incredibly strong yet much lighter than metal
  • Can be shaped into complex forms that would be hard to make with other materials
  • Resist corrosion and don’t wear out easily
  • Keep their shape even when hot or cold
  • Absorb vibrations better than metals

At Istar Machining, our 5 axis machining equipment lets us make even the most complex composite parts with perfect precision.

Industries We Serve

Our composite CNC machining helps many different industries:

Composite Materials We Work With

At Istar Machining, we have years of experience working with many different composite materials:

Carbon fiber is super strong but very light. We use our carbon fiber CNC machining services to make parts for:

  • Race car bodies and parts
  • Airplane wings and parts
  • High-end sports equipment
  • Camera mounts
  • Drones and robots

Also called fiberglass, this material is stronger than plastic but costs less than carbon fiber. Our fiberglass CNC machining creates:

  • Boat parts
  • Wind turbine blades
  • Car body panels
  • Electrical parts
  • Building materials

Known for being bullet-resistant, we machine Kevlar® composites for:

  • Safety equipment
  • Military parts
  • Sports gear
  • Phone cases
  • Motorcycle helmets

These mix different fibers together for the best properties. We make:

  • Titanium-CFRP parts for rocket engines
  • CFRP-aluminum parts for airplane wings
  • Kevlar®-carbon fiber armor plating

These have a pattern like a beehive inside. We machine these for:

  • Airplane floors
  • Racing car parts
  • Marine panels

Our Composite CNC Machining Equipment

We use only the best tools and machines for working with composites:

Our Composite CNC Machining Process

At Istar Machining, we follow a careful step-by-step process:

Step 1

Design Optimization

First, we look at your design and make sure it will work well with CNC machining. We use special computer programs to plan the best way to cut your part.

Step 2

Material-Specific Tooling

We pick the exact right tools for each material:
Diamond-coated end mills for carbon fiber
Special drill bits for fiberglass
Carbide tools for aramid fibers

Step 3

5-Axis Machining

Our advanced machines can cut from any angle, which means:
Complex shapes are possible
Fewer setups needed
Better accuracy
Smoother surfaces

Step 4

Post-Processing

After machining, we:
Remove any rough edges
Clean the parts thoroughly
Check every measurement
Make sure the finish is perfect

Frequently Asked Question

Most composite CNC machining services cost between $50-$250 per hour, depending on the material and complexity. Special materials like PEEK cost about 20% more than standard options like G10.

Yes! We use special ultrasonic cutting tools and diamond-coated bits that give clean edges without fraying or delamination.

Most orders take 5-10 days, but we have rush options for urgent needs. Larger orders of 100+ parts might take slightly longer.

We regularly achieve tolerances of ±0.003″ for most composite materials, and can reach ±0.001″ for critical dimensions when needed.

Yes, we can provide clear coat finishes, painting, polishing, and other surface treatments for composite parts.
