SMART MIRACLE® Coating

Newly-developed (Al,Cr)N coating with improved wear resistance.
The smoothig treatment of the coating layer reduces the cutting resistance and improves chip discharge significantly. This next-generation coating offers longer tool life and higher efficiency in machining difficult-to-cut materials.

IMPACT MIRACLE coating

For higher hardness, higher speed and longer tool life!
In comparison with the conventional coating single-phase nano crystal coating technology offers higher coating hardness and heat resistance.
When machining hardened steels it can be seen that the IMPACT MIRACLE coating offers a lower friction of coefficient and as such prevents abnormal damage such as chipping.

Features of IMPACT MIRACLE Coating

FEATURES OF IMPACT MIRACLE COATING
VC

MIRACLE Coating (Al,Ti)N

MIRACLE coating for high speed milling.
Miracle coating is produced by adding Al to the existing TiN coating.
This coating layer consists of a compound solid solution of (Al,Ti)N.
It has succeeded in improving the heat resistance during cutting and coating hardness, and thus delivers high performance in high hardness material machining and high speed dry cutting. It also has the high adhesion strength for the cemented carbide substrate, and extends the tool life significantly compared to conventional products.

MS+

(Al,Ti,Cr)N multilayer coating (MS Plus)

Suitable coating for a broad range of workpiece materials such as carbon steel, alloy steel and hardened steel of approx. 50HRC.
Our original coating technology enables a multilayer of (Al,Ti)N and (Al,Cr)N. It allows machining of a wide range of workpiece materials.

MS Plus CRN

CRN Coating

Specially designed for milling of copper electrode and copper alloy.
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 friction coefficient at high temperatures.

DLC

DLC Coating

Newly developed DLC coating.
Hardness similar to that of CVD diamond coating achieved 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.

DFC

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.

DF

Diamond Coating

Diamond coating for non-ferrous and new non-metal materials.
Owing to Mitsubishi’s unique plasma chemical vapor deposition (CVD) coating technology, great combination of coating hardness similar to that of natural diamond has been combined with a good adhesion to carbide substrates.
DF end mill series suitable for graphite machining.

V

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. The newly developed 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.
