Machine dry machining machine tools for thermal performance, chip speed, welcome home effect, accuracy and stiffness proposed strict requirements.

Tool tradition tool materials - high-speed steel has been gradually fade in turning, milling and other areas. Currently, the main material for dry cutting tools ultrafine particles carbide, polycrystalline diamond, cubic boron nitride, sic whisker toughened ceramics and nano-grain ceramics.

Research and development of coating technology to adapt to dry machining promising, tin, tialn coating technology can not meet the market needs, urgent need to develop higher hardness, better wear resistance, shock resistance, abrasion resistance and strong overall coating.

Particularity dry machining, powder high speed steel cutting tools should be large number of listed, and the need for size parameters and structural redesign or optimization tool; the parameters of the process must also be studied. In ø5mm Wurth drills, for example, with increasing drilling speed, drilling was significantly decreased, while cutting the 28m / min increased to 35m / min, the number of the 324 drilling fell 120, other tools Similar situations are when dry cutting.
