Revolutionizing Precision Machining: Unleashing the Power of CERATIZIT's ProMAX PowerLayer Coating Technology

written, compiled and edited by Bernard Martin

In the world of precision machining, staying ahead means having a cutting edge in more ways than one. Welcome to a new era of tooling excellence, where the ProMAX PowerLayer Coating technology is transforming the landscape for end mills.

This groundbreaking coating innovation is the game-changer that every machinist dreams of, enhancing the durability, performance, and longevity of end mills in ways that were once thought impossible. In this post, we'll take an in-depth journey through the ProMAX PowerLayer Coating technology, unlocking its secrets and exploring how it's redefining the standards of machining excellence.

Now, let's talk about coatings!  All of PROMAX coatings offered with their PROMAX Premium and Design-Rite XL products are manufactured in their very own High-Performance Coating Center. Having the entire coating process In-house enables PROMAX to ensure the highest coating quality. The PROMAX coating center is supported by the R&D department of thier sister company in Germany. With their help PROMAX is able to bring the latest European technology to the US market.

PROMAX PowerLayer

PROMAX successfully launched the PROMAX PowerLayer coating several years ago but we still find people who are quite impressed with the performance because they haven't explored this newer coating in the past few years.. This technology has been a game-changer for PROMAX Premium products. Internal tests have shown that a tool life compared to AlTiN can be improved by up to 100%. In combination with the 4-Flute series US007 and the 5-Flute series US556 PROMAX offers one the highest performance end mills on the US market.

PROMAX AlTiN

Aluminium Titanium Nitride (AlTiN).
​Sometimes branded as TiALN or TaliN by other manufacturers, AlTiN is the classic high-performance coating on the US market. The PROMAX AlTiN is able to outperform similar coatings available on the US market through their consistency of coating thickness. At their in-house coating center they strictly control the distribution of tools inside the coating machines, which is really what determines the coating quality. The PROMAX AlTiN is extremely heat resistant which shows great results when cutting Nickel based Alloys, Stainless Steel, Hardened Steels, Tool Steels and Titanium.

PROMAX ZrN

Zirconium Nitride (ZrN)
​This monolayer coating effectively reduces built-up edges when machining aluminum and titanium alloys. Recommended when machining medical grade materials and in other high heat resistant applications. Also for use in machining steels, alloyed steels, superalloys, Aluminum > 12%  Si, Aluminum < 12% Si, copper, bronze, brass and plastics. The PROMAX ZrN is able to outperform similar coatings available on the US market again, as a result of to the care they take to maintain the consistency of coating thickness. 

nACRo®

The nACRo® follows the coating structure of the original nACRo® coating developed by PLATIT, a swiss developer of coatings and coating machines. nACRo® has a nanocomposite structure that has increased hardness for scratch and higher heat resistance. This coating excels in “tough” difficult to cut materials including Steels, Hardened Steels, Alloyed Steels, and Superalloys.
