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.

Composite materials give you special benefits that regular materials like metal or plastic can’t match:
At Istar Machining, our 5 axis machining equipment lets us make even the most complex composite parts with perfect precision.
Our composite CNC machining helps many different industries:
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:
Also called fiberglass, this material is stronger than plastic but costs less than carbon fiber. Our fiberglass CNC machining creates:
Known for being bullet-resistant, we machine Kevlar® composites for:
These mix different fibers together for the best properties. We make:
These have a pattern like a beehive inside. We machine these for:
We use only the best tools and machines for working with composites:
Machine Type | What It Does | Why It Matters |
5-axis CNC machines | Cuts material from 5 different angles | Makes complex shapes with fewer setups, saving time |
Diamond-coated carbide tools | Cuts tough composites without wearing down | Creates clean edges on carbon fiber without fraying |
High-speed spindles (24k–48k RPM) | Spins cutting tools very fast | Perfect for detailed work on medical parts |
Dust extraction systems | Removes harmful dust while cutting | Keeps workspace safe when cutting fiberglass |
Ultrasonic edge trimming | Uses sound waves to cut cleanly | Makes smooth edges on bike frames and sports equipment |
When you work with us, you get:
We understand how different composites behave when machined
Our parts meet the tightest tolerances (±0.003" or better)
Every part is checked multiple times
5-10 days for most orders, with rush options available
We can help if your design needs adjustments
Competitive rates for all projects
At Istar Machining, we follow a careful step-by-step process:
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.
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
Our advanced machines can cut from any angle, which means:
Complex shapes are possible
Fewer setups needed
Better accuracy
Smoother surfaces
After machining, we:
Remove any rough edges
Clean the parts thoroughly
Check every measurement
Make sure the finish is perfect

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.
3D printers create amazing objects, but they have significant limitations. Understanding what 3D printers cannot do helps you choose the right manufacturing method. Here’s
Engineering drawings and CAD (Computer-Aided Design) are both used to design and manufacture products, but they differ significantly in format, creation, and application.
Choosing the right metal for your project is crucial. Titanium and aluminum are both lightweight metals widely used in various industries. This guide compares their properties to help
