Why Choose 3D CNC Machining?
- Super Exact: We can make parts with tiny details (as small as the width of a human hair)
- Works with Many Materials: From metals to plastics to wood
- Faster Than Hand-Making: Get your parts in days, not weeks
- Perfect Every Time: Each part matches your design exactly
Our 3D CNC Machining Tools
We use different kinds of machines based on what you need:
Machine Type | What It Does Best | When To Use It |
3-axis | Cuts from top and sides | Simple parts with flat surfaces |
4-axis | Adds rotation for more angles | Parts with curves and holes |
5-axis simultaneous machining | Moves in all directions at once | Complex shapes like airplane parts |
Materials We Work With
Our 5-axis CNC services can work with almost any material you need:
- Metals:
- Aluminum (6061-T6): Light but strong for airplane parts
- Titanium (Ti6Al4V): Super strong for medical implants
- Stainless Steel: Won’t rust, good for food equipment
- Brass: Good for parts that need to conduct electricity
- Plastics:
- PEEK: Works in high heat, good for engine parts
- ABS: Tough plastic for cases and covers
- Polycarbonate: Clear and strong for windows or lenses
Industries We Serve
Aerospace
We make parts for planes that need to be perfect and light. Our precision tooling helps keep planes safe in the sky.
Medical
Doctors need tools that work perfectly every time. We make surgical tools and implants that meet strict rules for safety.
Automotive
Car companies use our CNC prototype machining to test new designs before making thousands of parts.
Industrial
We make parts for robots, factory tools, and hydraulic systems that keep factories running.
How Our 3D CNC Machining Process Works
- Upload Your Design: Send us your CAD files (STEP, STL, or IGES format)
- We Check Your Design: Our experts make sure it can be made correctly
- Programming: We tell our machines exactly how to cut your part
- Machining: Our CNC prototyping machines carefully cut away material
- Quality Check: We measure every part to make sure it’s perfect
- Finishing: We can add special coatings or textures
Technical Details About Our Machines
Capability | Details |
Max Part Size | 40″ x 24″ x 20″ (bigger than a microwave) |
How Precise | ±0.001″ (thinner than a human hair) |
Surface Finishes | Smooth, textured, shiny, or matte |
Certifications | ISO 9001, AS9100, ITAR (important safety standards) |
Types of Parts We Can Make
- Complex Shapes: Parts with curves, holes, and angles that would be hard to make by hand
- Prototypes: Test your idea before making lots of parts
- Production Runs: From 1 to 10,000+ identical parts
- Custom Tooling: Special tools that help make other products
Benefits of Working with Istar Machining
Design Help
Our team can look at your designs and suggest changes to make them easier to make and less expensive. This is called Design for Manufacturing (DFM).
Fast Turnaround
Need parts quickly? Our machined components can be ready in 3-5 days for prototypes, or about 2 weeks for production orders.[^2]
Quality Guaranteed
We check every part with special measuring tools to make sure it matches your design exactly. Our precision machining meets the highest standards.
Wide Material Selection
With over 200 materials available, we can help you choose the right one for your project. Our experts know which materials work best for different jobs.
Common Applications of 3D CNC Machining
- Aerospace: Turbine blades, brackets, and lightweight parts
- Medical: Surgical tools, implants, and device housings using our 3D CNC milling expertise
- Automotive: Engine parts, prototypes, and custom accessories
- Electronics: Heat sinks, enclosures, and testing fixtures
- Robotics: Gears, arms, and custom end-effectors
5-Axis vs. 3-Axis Machining
When people think of CNC machining, they often picture 3-axis machines. But for complex parts, our 5-axis systems give big advantages:
- Fewer Setups: Make parts in one setup instead of multiple steps
- Better Surface Finish: The tool can always be at the perfect angle
- More Complex Shapes: Make parts that would be impossible on simpler machines
- Faster Production: Less setup time means your parts are done sooner
Our Finishing Options
After machining, we can add these finishes to your parts:
- Anodizing (makes aluminum harder and colorful)
- Powder coating (tough, colored layer)
- Bead blasting (gives a matte look)
- Polishing (makes parts shiny)
- Heat treating (makes metals stronger)

Frequently Asked Question
3D CNC machining is a way to make parts by cutting away material using computer-controlled tools. Think of it like a robot sculptor that can make exactly what you design. Our experts at Istar Machining use special software to tell the machines what to do.
We accept STEP, STL, or IGES files. SolidWorks files work great too!
Typically 3-5 days for prototypes and 2 weeks for production runs. Rush orders are possible!
Yes! Our 5-axis machining can create complex internal features like hidden channels and pockets.
We use Coordinate Measuring Machines (CMM) to check every dimension against your design.
