Coated Carbide Grade for Milling
Complete Coating Technology that Topples Current Tool Life Standards
Advanced Wear Resistance
By adopting the newly developed Al-Rich coating technology, the (Al,Ti)N with a high Al content ratio displays a very high hardness. This greatly improves oxidation and wear resistance.
Advanced Thermal Shock Resistance
The extreme heat resistance of this new series achieves amazing stability not only during dry cutting, but also when wet cutting where inserts are usually prone to thermal cracking.
Due to the Newly Developed Al-Rich Coating
Aluminium titanium nitride (Al,Ti)N is a compound of aluminium and titanium that is widely used as a coating for cutting tools due to its extremely hard and heatresistant properties.
The hardness of (Al,Ti)N increases as the Al content ratio increases, but with conventional technology, when the Al content ratio exceeds 60%, the crystal structure changes and the hardness of (Al,Ti)N decreases.
Using a new coating process based on Mitsubishi Materials' own original technology, a way in which an Al-Rich coating does not change its crystal structure even when the Al content is increased was developed. This also achieves a higher Al content and high the hardness of (Al,Ti)N.
Coated Carbide Grade for Milling MV1020 / MV1030
This grade has advanced wear and thermal shock resistance and also achieves stable cutting at unprecedented cutting speeds especially when machining steel and ductile cast iron, thus greatly reducing work time.
The new Al-Rich coating also provides excellent wear resistance. An unprecedented performance against sudden breakage was also realised especially during problematic wet cutting and when machining stainless steels.
Comparison of fracture resistance for intermittent cutting of SCM440 alloy steel
MV1030 is capable of high feed machining due to its excellent fracture resistance even during interrupted cutting.
Comparison of wear resistance when machining stainless steel SUS304
MV1030 suppresses damage at the cut border and can be expected to significantly improve tool life.
