Abstract
A method for cutting a rare earth alloy using a wire with abrasive grains fixed to a core wire, including the step of cutting the rare earth alloy with the wire traveling in a state that a portion of the rare earth alloy to be cut with the wire is immersed in a coolant containing water as the main component, the coolant having a surface tension at 25° C. in a range of 25 mN/m to 60 mN/m.

A method for cutting a rare earth alloy using a wire with abrasive grains faxed to a core wire, comprising the step of:
- cutting the rare earth alloy with the wire traveling in a state that a portion of the rare earth alloy to be cut with the wire is immersed in a coolant containing water as the main component, the coolant having a surface tension at 25° C. in a range of 25 mN/m to 60 mN/m.
A method for cutting a rare earth alloy using a wire with abrasive grains fixed to a core wire, comprising the steps of:
- allowing the wire wound around a reel bobbin to travel between a plurality of rollers;
- supplying a first coolant containing water as the main component to portions or the wire wound around the reel bobbin or portions of the wire traveling near the reel bobbin;
- and
- cutting the rare earth alloy with the traveling wire while a second coolant containing water as the main component is supplied to a portion of the rare earth alloy to be cut with the wire;
- wherein
- the first coolant bus a coefficient of dynamic friction against the rare earth alloy at 25° C. of 0.3 or less.
