COATING TECHNOLOGY
VQ Coating
These end mills have been treated with a newly developed (Al, Cr)N group coating which delivers substantially better wear resistance. The surface of the coating has been given a smoothening treatment resulting in better machined surfaces, reduced cutting resistance and improved chip discharge. This is the next generation of coated end mills that delivers long tool life when machining stainless steel and other difficult-to-cut materials.
CoatingFaster cutting speeds and longer tool life for high hardness materials and heat resistant alloys.
In comparison with conventional coatings, single-phase nano crystal coating technology offers higher coating hardness and heat resistance.
When machining hardened steels IMPACT MIRACLE coating offers a lower coefficient of friction and helps prevent abnormal damage such as chipping.

CRN Coating
Specially designed for milling copper electrodes and copper alloys.
CRN coating has been developed for copper alloy milling. It has superior wear resistance and excellent adhesion strength by using
Miracle coating technology. The excellent anti adhesion properties needed for copper machining has been achieved due to its low
coefficient of friction at high temperatures.

DLC Coating
For milling of aluminium alloys at high speed.
Hardness similar to that of CVD diamond coating achieved but with high adhesion strength.
Hardness similar to that of CVD diamond coating achieved but with high adhesion strength.
Mitsubishi Materials and NAGATA SEIKI have jointly developed a unique DLC coating that has substantially increased "adhesion strength" compared to previous DLC coatings.
Diamond Coating
Proprietary CVD diamond coating produces excellent wear resistance and smooth hole surface.
The newly developed CVD diamond coated carbide material achieves outstanding abrasion resistance and smoothness due to a proprietary fine multilayer diamond crystal control technology.
Diamond Coating
Diamond coating for graphite and non-ferrous materials.
Owing to Mitsubishi’s unique plasma chemical vapor deposition (CVD) coating technology, the diamond coating is affixed firmly to the substrate to ensure long tool life and prevent peeling.

VIOLET Coating
(Al,Ti)N coating, excellent adhesion strength for HSS tools.
Violet coating is the name of the technology of successfully applying a Miracle type coating to HSS substrate tools. Mitsubishi’s unique technology of applying (Al,Ti)N coating at the low temperatures required for HSS substrates, means that Violet coating has the same level of adhesion strength as Miracle coating. Additionally high film hardness and excellent oxidation resistance properties have also been realised.
