ECOCOOL 3000-DMJ, a high-performance coolant that can increase factory productivity and even improve work environments

Other coolants decay after three-to-four months, which causes foul odors, cloudiness, and stickiness (left photo).

In contrast, ECOCOOL 3000-DMJ does not decay even after eight months, and stays clean with no foul odors and no stickiness (right photo).

ECOCOOL 3000-DMJ also has excellent film strength, and is mixed with the right balance of extreme-pressure additives. It can be used with a range of applications, from heavy cutting to high-speed cutting.

Water-miscible coolant that can be used for a long time, with excellent general-purpose and antibacterial properties

The water-miscible coolants the company had been using decayed after three-to-four months, which was causing paint to peel from machines and rust to form on holders. This was also causing foul odors and stickiness, which was reducing workability and the quality of work environments. The company needed to stop production twice a year to exchange coolant. "Decayed coolant can have a negative impact all the way to the machine internals or even reduce machining precision, so we were constantly worried," explains Hajime Yokogawa, a manufacturing supervisor.

This all changed when the company took its first step toward automation and installed DMU 50 3^rd Generation, a 5-axis machining center. The company also took the advice of DMG MORI in switching to ECOCOOL 3000-DMJ, a microemulsion-type coolant made by FUCHS. "It's not realistic for a local factory of our size to use a different coolant for each work material, so we were excited about its excellent general-purpose properties," explains Yohei Takashima, president and CEO of Takashima Works. "The coolant also has excellent antibacterial properties and can be used for a long time, so we figured it would also reduce our waste oil costs and improve our work environment."

A coolant that does not decay, and that also improves machine uptime and workability

ECOCOOL 3000-DMJ is perfect for use with non-ferrous metals, and will not decay or emit foul odors even after eight months of use. "The coolant we were using would decay quickly in the heat of summer. We only added ECOCOOL 3000-DMJ, and it hasn't decayed even though we've yet to exchange it out," explains Mr. Yokogawa. "There's less work to do exchanging coolant and cleaning tanks, so machine uptime has also improved. The new coolant doesn't cloud or foam, so it doesn't get sticky. That's really improved workability!"

They had initially been using ECOCOOL 3000-DMJ only with DMU 50 3^rd Generation, but were so impressed with the coolant's decay resistance and its excellent lubrication and anti-foam properties, that they then began using it with their existing machining centers. They are now using it with a total of five of their machining centers (including DMU 50 3^rd Generation), and are now considering using it with other machining centers. "We manufacture parts related to national defense, so availability is of utmost importance," explains Mr. Takashima. "Thanks to ECOCOOL 3000-DMJ, we've maximized our time spent machining parts. We've been able to enhance the availability of our products just by switching coolant oil."

A high-performance coolant that's good for people and the environment

"DMG MORI gave us some excellent advice, and we think that they are simply the best when it comes to automation systems," explains Mr. Takashima when asked about his experience with DMG MORI. "We're now preparing to introduce the MATRIS Light robot system. We're very impressed with its flexibility, as it can be moved around to wherever it's needed."
The company now hopes to make its workplace even cleaner and worker-friendly, to attract younger workers to their local factory. "ECOCOOL 3000-DMJ is more resistant to decay, and switching to it has eliminated foul odors from within the factory. Along with reducing the actual workload on operators, we believe that this will be an important factor in changing how people think about local factories. Reducing the amount of waste oil can also reduce our environmental burden. We want to do what we can to help the environment."

No matter how things change, the company must continue to supply products, and help protect the nation and the lifestyles of the people living in it. Toward that end, Takashima Works will continue to bring passion to machining with the pride of a local factory.
