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

Rare-Earth Magnet Cutting

Precision Diamond Wire Sawing by Saehan Nanotech

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.

Diamond Wire Saw

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.

Proven Performance

Since the early 2000s, Saehan Nanotech has independently developed wire sawing and core drilling machines for hard and brittle materials. Our equipment has been successfully used for processing rare-earth magnets and exported to overseas clients who require precise, safe, and efficient machining solutions. In 2024, we also completed Korea’s first motor magnet cutting project, proving the reliability and scalability of our technology.

Applications

Saehan Nanotech’s Diamond Wire Sawing solutions are applied across multiple advanced industries, including:

Semiconductor components
Display materials
Electric motor and generator magnets
Optical glass and ceramic substrates

Our precision cutting systems allow complex geometries and tight dimensional tolerances that traditional sawing technologies cannot achieve.

Moving Forward

As demand for rare-earth materials continues to rise with the growth of the EV and renewable energy industries,
Saehan Nanotech remains committed to advancing diamond wire sawing technology and localized manufacturing.
Through continuous innovation, we aim to lead the global rare-earth machining market with reliable, high-precision, and eco-conscious solutions.

Advantages of the Horizontal Spindle Drilling Machine

saehan — Wed, 24 Jan 2024 21:54:46 +0900

Small chips are created during the silicon micro-hole drilling process. At this time, if chips accumulate in the hole, they will adhere to the tool, reducing tool life and causing tool breakage. Additionally, chips cause poor surface quality inside the holes. For this reason, chip evacuation during processing is a very important factor in improving silicon electrode hole quality and tool life.

However, in the case of vertical drilling, chip evacuation is structurally difficult. During drilling, chips can easily accumulate in the lower part. In particular, as the thickness of the material increases, it is difficult for chips to escape, and the processing difficulty increases significantly. At this time, the drill is easily damaged.

In the case of Saehan Nanotech's double-sided drilling machine, the spindles are installed horizontally. Because the tool drills from the side, the structure makes it easier for chips to come out compared to when drilling from the top down. During the perk drilling process, chips are naturally discharged along the movement of the drill. Additionally, specially designed cutting oil nozzles are attached to prevent chips from sticking to the tool. This results in longer tool life and improved hole quality.

Advantages of Both Sided Drilling Machine

saehan — Wed, 24 Jan 2024 18:31:09 +0900

Our equipment - Both sided drilling machine

Double-sided Drilling Machine

Holes are drilled from both sides at the same time

Unmanned processing time increases, reducing personnel cost, and improving productivity by up to 2x

Decreasing defects and increasing yields

Since there is no need for workers to turn over silicon electrodes, the defect rate due to human error can be greatly reduced. If the material is turned over in the middle of the process, problems such as incorrect spacing between holes may occur during this process. Additionally, the process has to be stopped in the middle, which takes a long time and requires a large number of people to be involved.

One Way Type Drilling Machine

Our equipment requires no human intervention from start to finish. Because the smart machine performs the entire process on its own, unmanned processing is possible even at night. Since the spindles attached to both sides drill simultaneously, production speed is also doubled.
