Filed: 1997-09-10
Abstract: PROBLEM TO BE SOLVED: To reduce the maintenance costs of a filter device, and reduce the amount of industrial waste. SOLUTION: Magnetic particles 6 are used as a filter element. The magnetic particles 6 are magnetized by an exciting means 7, and thereby, metal impurity in liquid is collected.

When chip generated from a worked surface of work at the time of cut work is used as the magnetic particles 6, a used filter element is constituted only by the chip. Recycle after use is utilized (it is used as the other manufacture, or it is used as a filter element again), and the amount for treating the used filter element as industrial waste is reduced.
