Low temperature around the cutting point can stabilize the machining quality, and it is not necessary to compensate the machine size.

There is no need for cooling fluid or oil, and the working spot can be observed directly. Also there is no damage to body.

Low temperature around the cutting point can reduce the tool abrasion, greatly extend the tool life and decrease the cost consequently.

Reduce the machine tool preparing time and improve the processing efficiency.

The chips can be recycled directly without environmental pollution. It accords with the standard of ISO14000.

Eliminate workpiece residual stress and improve processing accuracy.

Low temperature around the cutting point is convenient for machining titanium, magnesium, molybdenum, stainless steel, hard-cutting and thin materials.
