| 摘要 |
The present invention relates to a ultrasonic cleaner with a demagnetization function that supplies driving power to a three-axis demagnetization coil formed in all directions on an outer surface of a container and gradually decreasing a magnetic field formed in an object to be cleaned (for example, cutting tool) accommodated in the container at a magnetization point or more for a preset time for demagnetization to completely remove magnetic substances, such as metallic powders, adhered to a surface of the object to be cleaned. Therefore, it is possible to completely remove the magnetic substances, such as metallic powder, by demagnetization, as well as non-magnetic alien substances (for example, cutting oil) adhered to the surface of the object to be cleaned (for example, cutting tool). |
