What Is Prototype CNC Milling?

Prototype CNC milling is a way to make early versions of your parts. We use special computer-controlled machines to cut materials into the exact shape you need. Think of it like a super-precise carving tool that follows your design perfectly!

Our cnc prototype machining service helps you test your ideas before spending lots of money on mass production.

Materials We Can Use

We can make your prototype from many different materials, depending on what you need:

Material Type	Popular Options	Good For
Metals	Aluminum 6061/7075, Stainless Steel 304/316, Brass	Strong parts that need to last
Plastics	ABS, Nylon, PEEK	Lightweight, cost-effective testing
Specialty	PEEK, Brass, Nylon	Special needs like heat resistance

No matter if you need a simple bracket or a complex machine part, our 5 axis machining can handle it!

How We Help Different Industries

Aerospace Parts

We make lightweight, strong parts for planes and drones. These parts need to be super precise because lives depend on them. Our machines can make parts with tiny details down to ±0.001″ accuracy.

Medical Devices

For medical tools and implants, we work with special materials that are safe for the human body. These prototypes help doctors and engineers test new ideas that could save lives!

Automotive Testing

Car parts often need to be tested under tough conditions. We make engine parts, transmission components, and EV battery housings that can handle heat and stress during testing.

Learn More

Electronics Prototypes

Phone cases, heatsinks, and connector parts need to fit perfectly with other components. Our CNC milling gives them a smooth finish that looks great.

Robotics Development

Robot parts need to move smoothly together. We make housings for motors, joint pieces, and gripper parts that work without sticking or breaking.

Learn More

Industrial Equipment

For factory machines, we can make custom gears, valve bodies, and pump parts that stand up to heavy use. These parts often need to be made from tough steel.

Energy Systems

Wind turbine parts, solar panel mounts, and more need to last outdoors for years. We make corrosion-resistant prototypes that can handle harsh weather.

What Makes Our Service Special

Fast Turnaround

We know you need parts quickly! We can deliver in 1-5 days for most projects.

Precise Results

Our machines can make parts with tiny details as small as ±0.001″. That's about 1/4 the thickness of a human hair!

Multiple Machine Types

We have 3-axis, 4-axis, and prototype cnc milling machines to handle any shape you need, from simple to complex.

Expert Help

Our team will check your design before cutting starts. We might suggest small changes to make your part work better or cost less.

Surface Finishes We Offer

After milling your prototype, we can add different finishes:

Smooth polish– Makes parts look shiny and feel smooth
Bead blasting– Gives a matte, non-reflective surface
Anodizing– Adds color and corrosion protection to aluminum
Powder coating– Creates a tough, colored outer layer
