Powder coating is a type of coating that is applied as a free-flowing,
dry powder. The main difference between a conventional liquid paint and a
powder coating is that the powder coating does not require a solvent to
keep the binder and filler parts in a liquid suspension form. The
coating is typically applied electrostatically and then cured under heat
to allow it to flow and form a "skin." The powder coating process is
used to create a hard finish that is tougher than conventional paint,
making it more resistant to scratches, chipping, and fading. It is
commonly used on metals, such as aluminum, steel, and iron, as well as
on household appliances, automotive parts, and outdoor furniture. Powder
coating is an environmentally-friendly option as it produces less waste
and emissions than traditional liquid coatings. Powder Coating,Galvanized Iron Sheet,Sheet Metal,Decorative Metal Sheets Suzhou Gold ant Precision Sheet Metal Co.,Ltd , https://www.jmysheetmetal.com
Mitsubishi Heavy Industries (MHI) has recently introduced a groundbreaking machining tool that eliminates the need for cutting oil. This innovative technology is used in the production of hobs, shavers, and spiral bevel gears—key components in gear manufacturing. The tool has already been commercialized and is now available in the market.
Traditionally, machining tools are made from high-speed steel and coated with titanium nitride to enhance hardness. However, MHI's research team discovered in 1997 that adding a special titanium compound significantly boosts material hardness. Although the exact mechanism remains unclear, the company validated its effectiveness through extensive testing. Encouraged by these results, MHI accelerated the development of this new tool, securing 16 patents across Japan, Europe, and the United States.
The latest gear hobbing machine from MHI is equipped with these advanced cutting tools, each priced at around 15 million yen. What sets them apart is their ability to perform without cutting oil, while also offering four times the tool life compared to conventional tools. The cutting speed can reach up to 200 meters per minute, double the previous standard. As a result, the cost of machining a single part has dropped by approximately 40%.
Despite being 2.5 to 3 times more expensive than traditional tools, the benefits are clear: reduced production costs, lower environmental impact, and improved efficiency. Major automotive companies such as Chrysler in the U.S. have already decided to adopt the new technology, while several Japanese automakers are currently evaluating its potential. This innovation marks a significant step forward in sustainable and efficient metalworking.
