The blade matrix has higher resistance to plastic deformation. The cutting edge can withstand higher temperature without any loss of performance. The new substrate gradient can also reduce microcracks and improve the durability of the cutting edge line.
 
In order to ensure a more stable cutting action in the entire flow area, the groove shape and size at the cutting edge have been customized. A new breakthrough has been made in the microstructure of alumina coating by chemical vapor deposition (CVD). The edge line has better toughness and more wear resistance, especially suitable for intermittent cutting, thanks to the newly developed post-treatment process to a large extent.  
 
All of this means that the tool material technology has made substantial progress. Combined with the new generation of coated blade technology, the problem of turning tool performance in this wide and varied machining field with poor conditions has been fundamentally solved.
 
One of the major innovations in tool materials is the coating structure and adhesion. Of course, as a part of oxide ceramics and proved by practice, alumina is a mature tool material and a mature coating. This is a very effective blade protective layer, which is chemically inert and has low thermal conductivity. Through diffusion, the crescent crater wear resistance is very high. The melting point of this material is above 2000 ℃, and it is very hard due to its close packed crystal structure.
 
To date, conventional alumina coatings have random crystal orientations. These alumina coatings have satisfactory processability, and can overcome some shortcomings caused by bad conditions of cutting edge line and rake face. The research shows that if the actual crystal direction is controllable, many cutting edge characteristics are also controllable. More importantly, it has been significantly improved.
 
Inverio coating is an innovation of alumina and tool material technology, with unidirectional non arbitrary crystal orientation. In the whole CVD process, this can only be achieved by using a unified way to control crystal growth. All hard aluminum alloy crystals are arranged in the same way to make the coating structure stronger and more uniform. The new features are more beneficial to withstand the force and temperature in the flow area. In fact, a new contact surface of the rake face has been formed.
The closely arranged atomic planes, facing the area contacting with the debris, have better resistance to crater wear, which is the main diffusion wear mechanism of steel turning under heat and pressure. The flow area of iron filings dissipates heat more effectively along the crystal plane. Another effect is the ability to resist microcracks. Cracks are formed in the weak parts along the horizontal direction, and the durability of the coating is improved due to the slow, uniform and controllable wear.
The new effect, combined with the adhesion of blade coating, also reduces the wear of the "false" crescent depression of the pressed piece. The inner coating is composed of fine titanium carbonitride, with columnar structure, hardness and strong abrasion resistance. In fact, the tool life has been extended and the cutting speed has been improved - these are the driving forces for the manufacturing industry to make substantial progress. The blade edge line determines the part quality and the blade damage rate. Now it is more flexible, improving the blade performance and the predictability of processing parts.
