Machine tools industry globally uses expensive metalworking fluids to cool and lubricate workpieces and cutting tools. Finnish firm Oy ECE EcoCooling Engineering has now developed a method that uses only ionized and cooled air for lubrication instead of conventionally-used, environmentally-hazardous oil-based fluids.

The green and clean method, EcoCooling, is the result of long-term, interdisciplinary R&D from the same team that developed the technology behind Amazon’s ground-breaking family of front-lit Kindle devices. Now the group of scientists, engineers and experienced business people from various disciplines has developed a dry, clean and environmentally friendly method to lubricate metal workpieces with ionized and cooled air without using any emulsions.

“Workshops have wanted to get rid of fluids and many have tried to find a solution to the problem, but with poor results. Now we have the answer to this demand, since EcoCooling can be used even with the hardest known metals like chrome, titanium and tungsten carbides,” said Leo Hatjasalo, Co-founder and CEO of EcoCooling.

Targeting the $ 12 bn metalworking fluids market
The global market value for metalworking fluids is estimated at approximately $ 12 billion this year. It is growing steadily, with estimates for the global market value for machine tools expected to grow from $ 120 billion to $ 150 billion in five years’ time. The growth is driven, for example by the accelerating need for components in the aerospace, automotive and transport sectors.

“EcoCooling is based on the fact that ionized air penetrates the cutting zone and forms a dry lubricant that decreases cutting friction and generated heat, at the same time speeding up the oxide layer formation. The process is patented on all continents, and at the moment we are validating it to include all types of machine tools,” explained Hatjasalo.

Hatjasalo emphasises that EcoCooling is not only a way to cut down the costs of emulsions, but also a way to improve productivity through higher cutting speed, reduced wear of cutting tools and minimised maintenance costs. “Since the metal chips are not contaminated by any fluids, they can also be fully recycled without cleaning. Another big advantage is that it eliminates toxic fluid waste and fumes, in addition to minimizing CO2 emissions, since no oil is used,” he added.

The technology makes it possible to build smaller and cheaper metalworking machines, since the EcoCooling unit is very compact in size. “The unit does not need any service and it has proved to prolong the lifetime of the cutting tools significantly”, Hatjasalo said. “The system can also be easily retrofitted to older machine tools.”

The big leap is still ahead
During the past few years, EcoCooling has been successfully trialled in numerous commercial tests in demanding surroundings internationally. Now that the process has proved to give excellent results, big savings and substantially less environmental impact, the aim is to create a versatile EcoCooling product family that includes all machine tools in addition to just turning machines.

“We are also planning to integrate the system to suit different CNC machine tools and to create optimal solutions for all machine tools and workshop environments. However, for that purpose we need more funding than we can raise on our own. Therefore, the next step is to find an industrial partner to help us to commercialise EcoCooling globally and to develop the ways the technology can be used,” said Hatjasalo.

Oy ECE EcoCooling Engineering Ltd is part of a portfolio of Finnish high-tech companies developing world-leading technologies, like the front-lit technology used in Amazon Kindle-devices. It was developed and industrialised by the portfolio company Modilis Ltd, which was sold to Amazon in 2010.

The patented, ionized EcoCooling air-cooling system is a completely different story, since it is aimed at eliminating the use of harmful metalworking fluids in industrial material cutting processes. The system has been industrially researched and developed since the end of the 1980s. It has been thoroughly tested in real-life processes and assessed in 3rd party tests and is now ready for global commercialization with the support of an industrial partner that operates globally.
