Rare-Earth Magnet Cutting — Precision Diamond Wire Sawing by Saehan Nanotech

 

Cutting rare-earth materials such as Neodymium (NdFeB) magnets requires advanced technology that combines precision, safety, and efficiency. Due to their brittle nature and hardness, these materials cannot be processed with conventional sawing methods.

That’s why Diamond Wire Sawing (DWS) has become the standard technique for rare-earth magnet machining.

🔹 Diamond Wire Sawing (DWS) Technology

DWS uses diamond-coated wire(sometimes uses diamond slurry) as the cutting medium, allowing precise and clean cuts even on extremely hard materials. During cutting, a coolant (usually water-based) is essential to control temperature and prevent flammable dust from igniting. This combination of abrasive diamond wire and coolant-based heat management enables stable, high-precision machining without damaging the material surface.

🔹 Saehan Nanotech’s Approach to Rare-Earth Sawing

At Saehan Nanotech, we have developed and refined specialized multi-wire sawing machines designed specifically for rare-earth magnet processing.

Our systems feature:

• Multi-Wire Saw Machines capable of cutting multiple pieces simultaneously
• Precision control algorithms to stabilize wire tension and feed rate
• Customizable configurations for both straight and arc-shaped cuts
• Enhanced coolant flow and filtration systems for safe and clean operation

These features ensure uniform cutting surfaces, minimal material loss (low kerf width), and high repeatability — essential for mass production and R&D applications alike.
