Technical Highlights

Proprietary Tilting / Rotating Technology

Exclusive ingot tilting and rotating mechanism adjusts cutting angle in real time — up to 3× productivity vs. conventional methods. No other Korean wire saw manufacturer offers this.

Diamond Wire — Maximum Material Yield

Ultra-fine diamond-plated wire minimizes kerf loss to under 200μm. More slices per ingot = lower cost per wafer. Superior surface finish reduces downstream polishing.

Fully Customized Machine Manufacturing

Every ANT-WS machine is engineered to your material, workpiece size, thickness spec, and throughput target. Wire guide roller geometry, coolant systems, and tensioning configured per order.

Rare Earth Magnet Specialist

NdFeB and SmCo magnets require diamond wire sawing with water-based coolant. Saehan Nanotech pioneered this in Korea — completed Korea's first motor magnet cutting project in 2024.

Recipe-Based Process Optimization

Over two decades of accumulated cutting data. Material-specific process recipes validated through real production runs.

Full Lifecycle Support

Product development, design, manufacturing, installation, training, and after-sales service — all in-house.

Cast-Iron Monolithic Frame

The spindle housing is cast as a single monolithic structure to minimize vibration and ensure high structural rigidity. A water-cooled body further suppresses thermal displacement during machining.

Integrated cast spindle housing design
Water-cooled (water-jacket) body structure

Dual-End-Supported Main Roller

Supporting the main roller on both ends improves rotational accuracy and extends ingot cutting length. High-speed wire operation maximizes throughput.

Higher rotational accuracy + longer cutting span
High wire speed → higher productivity
