WHO WE ARE

Precision Machine Tools
for Critical Materials

Saehan Nanotech is a precision machine tool manufacturer specializing in equipment for ultra-precision machining of hard and brittle materials — the foundational substrates that underpin the semiconductor, display, defense, and clean energy industries.

We handle the entire value chain in-house: product development, mechanical and control system design, manufacturing, assembly, quality testing, installation, operator training, and after-sales service. No outsourcing. No third-party contractors. Every machine that leaves our factory is built, tested, and supported by the same engineering team.

WHY SAEHAN NANOTECH

What Sets Us Apart

100% In-House

Every machine is developed, designed, manufactured, and serviced by our own team. When you call for support, you speak to the engineer who built your machine.

Custom-Built Per Order

No off-the-shelf machines. Every unit is engineered to your specific material, workpiece geometry, throughput target, and facility requirements.

Decades of Process Data

25+ years of cutting, grinding, drilling, and polishing hard brittle materials. Our process recipes are validated through real production — not simulations.
