Water-base fluids are preferred in high-speed turning, milling, and grinding because of their greater cooling effect. These may be soluble oils or chemical solutions. Except for grinding, which depends almost entirely on cooling and flushing, some chemical activity is always desired and is generally provided by chlorine, amines, or other chemicals.

In practice, grinding by means of diamond grinding wheels is applied in machining of such elements. The process is possible if both feed rate and machining depth are small. In case of particularly demanding elements, electrochemical grinding (ECG) is applied. It is a type of a hybrid process combining various types of effect upon the workpiece.
