Iwaki, Japan – January, 2026 – Tungaloy Corporation (President: Satoshi Kinoshita, Head Office: Iwaki City, Fukushima Prefecture) announces the expansion of its DLC-coated DS2000 Series, optimized for aluminum and non-ferrous metal machining, delivering superior surface finish, extended tool life, and enhanced productivity across turning and milling operations.
Challenges and Trends
In recent years, the trend toward lightweight design and higher efficiency has accelerated across a wide range of industries, including automotive, aerospace, semiconductor, robotics, and housing materials. Among these, the adoption of aluminum alloys and non-ferrous metals—known for their lightweight yet high-strength properties—has been rapidly expanding. Consequently, the demand for high-precision and efficient machining of these materials is increasing.
However, aluminum is prone to issues such as built-up edge formation and burr generation during cutting, making it difficult to maintain stable tool life and consistent surface finish quality. In the market, there is a strong need for machining solutions that can overcome these challenges while achieving both productivity and quality.
