Apparatus and method for machining workpieces by flushing working liquid to the tool-and-workpiece interface

摘要

Disclosed are improved apparatus and method for effecting a required machining on workpieces with working liquid flushing to the tool-and-workpiece contacting place. Gas such as air is ejected to the tool-and-workpiece contacting place, thereby making the working liquid to forcedly invade into the tool-and-workpiece interface. Thus, cooling effect is enhanced to maximum while saving the quantity of working liquid, still assuring that the products of comparable or even higher quality are provided.
