Dry cutting has the following significant advantages:

· Because without coolant, reduces the production cost;

· Environmental pollution, no harm for the operator, in favor of cleaner production;

· Improve cutting efficiency, part of the workpiece can be achieved in the car instead of grinding;

· Improve the surface quality of the workpiece;

· Wide range of applications, turning, milling, planing, drilling, boring, and other areas of high-speed steel cutting tools, can dry cutting its energy exhibition.

Applications dry cutting technology

After tialn coated high-speed steel broaches, in geometry and tooth-liter capacity and other aspects were optimized, using semi-dry cutting, broaching under normal conditions, the life of the coating broach broach higher than uncoated 20 % or more, and pulled surface quality is also good.
