Our Complex CNC Machining Abilities

We use top machines and smart planning to make your complex parts right the first time.

Multi-Axis Machining

Our 5-axis machining centers can cut from many angles in one setup. This means:

  • Better accuracy for your parts
  • Fewer setups that could cause mistakes
  • Can make undercuts and deep cavities
  • Faster production time

Material Expertise

We work with many materials, even the tough ones:

Material Type

Examples We Machine

Good For

Metals

Aluminum, titanium, stainless steel, Inconel®

Aircraft parts, medical tools

Hard Plastics

PEEK, Ultem®, polycarbonate

Chemical-resistant parts, clear components

Special Materials

Ceramics, composites

High-heat applications, lightweight strength

For the toughest jobs, check our titanium CNC machining service.

Micro-Machining

Need super small parts? We can make parts as tiny as 0.5mm with amazing detail. Our tools and skills let us:

  • Cut tiny slots and holes
  • Make thin walls without breaking them
  • Keep tight measurements on very small features

High-Volume Production

Even with complex parts, we can make many of them. Our shop can:

  • Make one prototype or thousands of parts
  • Keep every part the same with special checks
  • Deliver on time for your production needs

How We Make Complex Parts Possible

Advanced Technology

Our shop has the latest CNC tools:

  • Modern machines that cut with amazing accuracy
  • Computer programs that plan the best way to make your part
  • Measuring tools that check parts are perfect

Expert Team

Machines are only as good as the people running them. Our team:

  • Has years of experience with hard jobs
  • Knows how to solve tricky machining problems
  • Checks every step to catch issues early

Quality Checks

We don’t just make parts—we make sure they’re right:

  • Parts measured with special tools (CMM)
  • Surface finish checked for smoothness (as fine as 0.2µm Ra)
  • Every part compared to your design

Industries We Serve

Aerospace

In aerospace, parts must be perfect. We make:

  • Turbine blades with complex curves
  • Fuel system parts that must not leak
  • Structural components that are light but strong

Aerospace CNC machining is one of our specialties.

Medical

For medical devices, we deliver:

  • Surgical tools with perfect balance and grip
  • Implants made from body-safe materials
  • Diagnostic equipment parts with precise fits

Automotive

Car makers trust us for:

  • Engine parts that must handle heat and stress
  • Lightweight parts for better fuel economy
  • Test parts for new designs

Energy

The energy sector needs tough parts:

  • Valves and manifolds for high pressure
  • Heat-resistant components for power generation
  • Corrosion-resistant parts for harsh environments

The Complex CNC Machining Process

When you work with us, here’s what happens:

  1. Design Review – We look at your drawing and suggest changes to make it easier to make
  2. Material Selection – We help pick the right material for your needs
  3. Programming – Our experts plan how the machines will cut your part
  4. First Article – We make one part and check it carefully
  5. Production – After approval, we make all your parts
  6. Quality Control – Every part is checked against your specs
  7. Finishing – We add any treatments like anodizing or polishing
  8. Delivery – Your parts arrive on time, ready to use

Why Choose Istar Machining

We’re not like other shops because:

  • Experience – 15+ years making the hardest parts
  • Equipment – Top machines for complex work
  • Problem-Solving – We find ways to make “impossible” parts
  • On-Time – We meet deadlines, even for rush jobs
  • Support – Our team helps from design to delivery

Cost Factors in Complex CNC Machining

Complex parts cost more than simple ones. Here’s why:

  • Setup Time – More angles mean more setups
  • Programming – Complex shapes need careful planning
  • Machine Time – Precision takes longer
  • Material – Exotic materials cost more
  • Inspection – Complex parts need more checking

But we work to keep costs down by:

  • Finding better ways to make your part
  • Suggesting small changes that save big money
  • Using our experience to avoid problems
