Method for cutting rare earth alloy, method for manufacturing rare earth alloy plates and method for manufacturing rare earth alloy magnets using wire saw, and voice coil motor

A method for manufacturing rare earth alloy magnets including an Nd—Fe—B compound, comprising the steps of:

• making a sinter out of a rare earth magnetic alloy powder;
• and
• separating a plurality of rare earth alloy magnets from the sinter,
• said separating step comprising the steps of,
• supplying slurry containing abrasive grains onto a wire;
• machining the sinter with the abrasive grains, interposed between the wire and the sinter, by running and pressing the wire against the sinter;
• and
• removing sludge of the sinter out of the slurry to maintain a viscosity of the slurry within a predetermined range.
