<P>PROBLEM TO BE SOLVED: To provide a metal working device that achieves metal working with high accuracy and at high speed by avoiding the occurrence of vibration at working part even when a huge amount of coolant is supplied to the working part, without requiring a waste oil disposal or cleaning of a product, while preventing oxidation of a metal to be worked. <P>SOLUTION: The metal working device 100 includes: a tool 121 for working the metal W to be worked; and a coolant supplier 130 for supplying the coolant L to the working part A between the tool 121 and the metal W to be worked. The coolant L is produced by being subjected to deaeration process where a dissolved gas is removed and hydrogenation process where hydrogen is added, with respect to water. <P>COPYRIGHT: (C)2012,JPO&INPIT |
