With the advancement of the level of the machining industry, modern tool products are not only improved in the use of life, but also reduce the pollution during cutting, try to achieve only the rust inhibitor and no organic matter, the maximum limit of the cycle of recovery.
With the development of technology, the demand for the appearance of data is getting higher and higher. In recent decades, the accumulation of various gas phase stacking skills has enabled the research and application of external engineering skills to be carried out with each passing day. These skills not only fulfill the needs of mechanical functions, such as wear resistance, friction reduction and corrosion resistance, but also highlight the magical, optical, optoelectronics, thermal, superconducting and biological aspects of the surface-related functional data. Appearance engineering not only makes low-cost metal materials play a greater advantage in terms of function and efficiency, but also has become an important method for researching various new coatings and film materials, and has infinite potential for application.
Turning and drilling are not the same, milling cutters should also consider the characteristics of their intermittent impact. The pre-existing coatings focus on wear resistance and the primary goal is to improve hardness. Such coatings represented by titanium nitride have a high coefficient of conflict (0.4 to 0.6), and a lot of heat energy will occur during the collision with the workpiece during processing. In order to prevent the tool from overheating, the deformation affects the machining accuracy and extends the service life, the cutting fluid is generally used.
To deal with the problem of cutting or removing cutting fluids, tool plating should not only give the tool a long life, but also have a self-lubricating function. However, these years of research indicate that the hardness of diamond-like coatings (also known as graphite-like coatings) based on SP2 layout can reach 20-40 GPa, but there is no doubt about the catalytic effect of ferrous metals. The conflict coefficient is very high. Low and excellent moisture resistance, it can be used for dry cutting when cutting. The life expectancy is doubled compared with non-coated knives. There is no doubt about processing steel materials, so it has caused coating companies and tool manufacturers. Great hobby.
Following the focus of the manufacturing industry on the tool profession, the demand for tool products in the mall, the tool attack is about to quickly change the form of development, improve the skill level and product quality, try to reduce pollution, recycle, and develop green.
