components New Zubora

components New Zubora lubricant series for machining They cover a wide range of applications With the Zubora 57 series, the lubricant experts from Zeller+Gmelin present modern, water-miscible cooling lubricants for machining. The products, which are free of boron and formaldehyde separators, cover a wide range of applications with their individually tailored additive concept: from normal to tough steel, aluminium or cast materials. Even the processing of non-ferrous metals is possible in many ways. According to Zeller+Gmelin, the new water-miscible Zubora cooling lubricants make a convincing contribution to economical and sustainable production for a wide range of machining tasks. Products from this new series can be used even for the most demanding machining oper ations. For example, Zubora 57 H Plus is also ideally suited for grinding as a lubricant for mediumduty machining opera tions. The Extra and Ultra products are even more powerful. Due to a high proportion of polar additives, Zubora 57 H Extra guarantees an outstanding reliability even for difficult machining tasks. With additional EP/AW additives, Zubora 57 H Ultra (for hard water) or Zubora 57 S Ultra (for soft water) ensures maximum process reliability even for the most difficult machining tasks. In addition, the semisynthetic lubricants with a mineral oil content of 30 % offer excellent corrosion protection. Long service life guaranteed: with the optimally coordinated formulation, the water-miscible Zubora cooling lubricants of the 57 series score with an excellent price-performance ratio As studies from the development of lubricants at Zeller+Gmelin show, the products have a good long-term stability. Various 5 and 10 % emulsions were tested, made up with water at 40 ° dH. The samples were then subjected to an aging test. The samples were stored over a period of four weeks at room temperature or at 40 ° C. Even in the “endurance test” at 40 ° C, the samples showed no optical changes after four weeks, which proves a good long-term stability. This significantly extends the maintenance intervals, which leads to long-term cost savings for the equipment. Whether room temperature or 40 ° Celsius, without flocculation and cloudiness: the cooling lubricant Zubora 57 H Ultra proves a high long-term stability further information: www.zeller-gmelin.de 46 no. 3, September 2020

On the verge of a green and clean era in the metal tool industry: components Ionized, cooled air to replace metalworking fluids Expensive metalworking fluids are no longer needed to cool and lubricate workpieces and cutting tools in the machine tool industry. Instead, there is now a proven green and clean method, EcoCooling, that uses only ionized and cooled air and has none of the environmental hazards and costs related to oil-based fluids. 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 businesspeople 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”, says Leo Hatjasalo, co-founder and CEO of EcoCooling. “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.” Big market The global market value for metalworking fluids is estimated at approximately 12 bn $ this year. It is growing steadily, with estimates for the global market value for machine tools expected to grow from 120 bn $ to 150 bn $ 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”, Hatjasalo explains. “The process is patented on all continents, and at the moment we are validating it to include all types of machine tools.” EcoCooling utilizes cooled ionized-air flow in the working zone to form a dry lubricant, which decreases cutting friction and generated heat and speeds-up oxide layer formation “The unit does not need any service and it has proved to prolong the lifetime of the cutting tools significantly”, Hatjasalo says. “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”, Hatjasalo says. “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 commercialize EcoCooling globally and to develop the ways the technology can be used.” Hatjasalo emphasizes 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 minimized maintenance costs. “Since the metal chips are not contaminated by any fluids, they can also be fully recycled without cleaning”, he says. “Another big advantage is that it eliminates toxic fluid waste and fumes, in addition to minimizing CO 2 emissions, since no oil is used. “The technology makes it possible to build smaller and cheaper metalworking machines, since the EcoCooling unit is very compact in size.” The experienced team behind EcoCooling: Juha Hatjasalo, Leo Hatjasalo, Jori Oravasaari and Jarmo Maattanen (from left to right) further information: www.ecocooling.fi no. 3, September 2020 47
