What Is Ultra Precision Grinding?

Ultra precision grinding is like regular grinding but MUCH more exact. We can make parts that are within ±0.0005mm of being perfect – that’s thinner than a sheet of paper split 200 times!

Our grinding is so exact that we can make things that:

  • Work perfectly in medical tools that go inside the human body
  • Help rockets fly to space
  • Make computers work faster
  • Help cars run more smoothly

Our Ultra Precision Grinding Capabilities

What We Can Do

How Exact We Can Make It

Why It Matters

Make parts within ±0.0005mm

5 times more exact than normal machines

Your parts will fit perfectly every time

Create surfaces as smooth as 0.15Ra~0.4Ra

Smoother than a mirror

Less friction, longer part life

Work with super hard materials

Even tungsten carbide and ceramics

Nothing is too tough for our machines

Use ultrasonic assistance

40% less tool wear, 30% smoother finish

Better parts, lower costs

Machine diameters from 5mm–300mm

From tiny to large in one setup

Flexibility for any project

Materials We Can Ultra Precision Grind

We can grind almost anything with our ultra precision grinding equipment. Here are some of the tough materials we work with:

  • Hard Metals: Hardened steels, tungsten carbide, aerospace alloys
  • Ceramics: Silicon carbide, optical ceramics
  • Crystals: PMN-PT ferroelectric crystals
  • Glass: Optical-grade glass for lenses and mirrors
  • Medical-Grade Materials: Biocompatible metals for implants

Do you need custom titanium machining with ultra-precision? We excel at that too!

Industries We Serve With Ultra Precision Grinding

Our ultra precision grinding service helps many important fields:

Aerospace

We make parts for airplanes and spacecraft that must be perfect. Our tight tolerance machining helps engines run better and satellites work longer. Need aerospace machined components? We can help!

Medical

Doctor’s tools and body implants need to be perfect. Our sub-surface damage prevention techniques make sure medical parts are safe and work right every time.

Semiconductor

Computer chips need super flat surfaces. Our grinding makes surfaces so smooth that microscopic circuits work perfectly. We use grinding process optimization to ensure perfect results.

Optics

Telescope mirrors, laser parts, and camera lenses need to be perfect shapes. Our surface roughness reduction makes optical parts that show clear images without flaws.

Automotive

Car engines and safety systems need perfect parts. We make fuel injectors, brake parts, and transmission pieces that make cars safer and more efficient.

Why Our Ultra Precision Grinding Process Is Special

At Istar Machining, we don’t just have good machines – we have a special process:

  1. Zero Thermal Distortion: We keep parts cool so they don’t warp
  2. Ultrasonic Assistance: Special sound waves help grind better
  3. Ductile-Regime Grinding: We can grind glass and ceramics without cracks
  4. Full Checking: We check parts with powerful microscopes and lasers

If you need precision medical machining, our ultra precision grinding is perfect for your most demanding requirements.

Our Grinding Equipment

Our shop has the best grinding machines in the world:

  • CNC Cylindrical Grinders: For perfect round shapes
  • Jig Grinders: For complex shapes and holes
  • Centerless Grinders: For long, round parts
  • Surface Grinders: For flat surfaces with ultrasonic help
  • Multi-Axis CNC Grinders: For complex shapes with angles

We also use special diamond and CBN grinding wheels that stay sharp longer.
