Milling tools have to deal with a huge amount of strain from heat and friction. If you regularly run your milling machine at high speeds and feeds. Then you have probably experienced first hand just how quickly cutting edges of your tools can degrade. One way to extend working life of your tools is to use TiAlN coated end mills for your milling operations.
Titanium Aluminum Nitride, or TiAlN, is a metastable hard coating used to provide little extra protection. On end mills and drill bits. This compound is made up of titanium, aluminum, and nitrogen. TiAlN is extremely hard, making it similar to other ceramic coating materials such as TiN. Manufacturers design all these tool coatings to extend. The life of your tools, but TiAlN-coated end mills perform especially well for tools that operate at high speeds.
One of the distinct advantages of using TiAlN over other tool coatings is the fact that the aluminum content of coating oxidizes. When used in high heat applications. This oxidation process causes a thin layer of aluminum oxide to build up on surface of the end mill. Which helps to protect surface of the tool from oxidizing. as a result of exposure to high temperatures. The aluminum oxide layer also helps to further insulate the body of the tool to prevent heat fatigue.
Another unique function of using tools coated with TiAlN is the fact that the coating itself is hard enough to protect the surfaces of your tools. This provides the extra wear resistance needed to keep your tool’s cutting edges sharp.TiAlN treatment extends the lifespan of even hard and stable solid carbide cutting tools
If you have a job that requires high speeds and feeds, then it is also worth noting that TiAlN has a low coefficient of friction. Making tools treated with this coating ideal for high speed machining. This low coefficient of friction also makes TiAlN tools the ideal general purpose option for cutting into ferrous materials such as cast iron and stainless steel.
When you imagine coating a tool, it might seem like such a process could soften the edges. This would certainly happen if manufacturers applied the coating like paint, but the process involves a more complex method.
Manufacturers deposit most tool coatings using a process called physical vapor deposition.
Although the exact steps vary depending on the type of machinery, the process places the tool in a vacuum. Within the vacuum chamber, the coating material vaporizes and then solidifies. Forming a microscopically thin layer of coating on surface of the cutting tool.
