Generally, in most metal processing operations such as rolling, drawing, cutting, and grinding, a very high friction force is applied between the metal being worked on and the machine tool.

Therefore, in order to increase the lubricity between the workpiece metal and the machine tool and remove the high heat generated during the friction process, it is common to use water-soluble metalworking oils that have both lubricating and cooling properties, such as rolling oil, drawing oil, cutting oil, and grinding oil.

This processing oil is not used once but is used repeatedly. To achieve this, it is used by removing impurities such as oxidized scale contained in the processing oil, metal chips resulting from processing, and other foreign substances such as dust around equipment.
