Rare Earth Magnet Wire Saw

Yes. We build to order in 2, 3, 4 and 5 roller configurations. The number of rollers changes the shape and the number of cutting areas the wire web forms, so tell us your material specification, stacking method and target output and we will propose a suitable configuration. Roller diameter is designed within a Ø150–Ø250 mm range; the ANT-WS1875UD standard is a 3-roller configuration at Ø180 × 750 mm.

The workpiece geometry and the way it is held are different. Silicon comes as a round ingot, so tilting and rotation mechanisms matter; a sintered magnet is a rectangular block, so bonding and jig pallet design are what count. The ANT-WS1875UD bonds magnet blocks to a beam and loads them on a pallet, and is built around a twin work table structure.

Sintered magnets are hard and highly brittle, so cracking and chipping occur easily during cutting. Electroplated diamond wire cuts with a fine wire in a grinding-like action, which reduces impact, and the narrow kerf also reduces the loss of expensive rare earth material.

Yes, and it comes down to the structure. Most of the machine is made from GC300 high-rigidity cast iron (equivalent to ASTM A48 Class 40), which resists deformation in a way a welded frame does not, and the roller shafts are supported at both ends inside an integrally cast housing to secure rotational accuracy. Coolant flows through channels cast into the body and draws heat away from the bearings directly: in our in-house measurements, applying this body cooling brought the main roller bearing temperature down from 65°C to 30°C. Because the body temperature stays constant, thermal displacement is suppressed and the roller axes do not drift out of alignment — so thickness variation stays under control and cut quality holds even over long machining runs.

Yes. Saehan Nanotech cuts customer material daily in its own machining division, so we can run tests based on your magnet material and target thickness. We propose wire specifications, cutting conditions and machine configuration from the test results, and the machining conditions (the recipe) are handed over with the machine.

Yes. Saehan Nanotech has been supplying wire sawing and core drilling equipment to the overseas magnet industry since 2011. Design, manufacture, inspection, installation and training are handled directly by our own engineers, and post-installation technical support is provided to the same standard.
