ZUBORA ® TDD ZUBORA ® TKS ZUBORA ® TXS ZUBORA ® THS ZUBORA ® SYSTEMCLEANER 6 Processes Cast iron Synthetic grinding products Materials 3% 4° – 20° dH 0% 3% 2,1 9,1 Long-term stable, synthetic and water soluble cooling lubricant for the production of clear coolant solutions especially for grinding. Also suitable for light machining. The product provides particularly high corrosion protection and can be used with soft, medium hard and hard water up to 20° dH and more. Particularly poor foaming properties facilitate observation of the grinding process. 0% 2,5 – 3,5% 3% 4° – 20° dH 1,4 9,1 Synthetic, water soluble cooling lubricant, especially for grinding. Particularly suitable when followed up by CHC or solvent degreasing (cleaning). The product provides particularly high corrosion protection and can be used with soft, medium hard and hard water up to 20° dH and more. Particularly poor foaming properties facilitate observation of the grinding process. 3% 4° – 20° dH 0% 5 – 7% 1,4 9,1 Synthetic, clear water soluble cooling lubricant for grinding processes and also for up to medium heavy machining. Highly suited for profile or deep grinding of alloyed stainless steels. The product provides particularly high corrosion protection and can be used with soft, medium hard and hard water up to 20° dH and more. Also suitable with solvent-based cleaning (de-greasing) afterwards. Particularly poor foaming properties facilitate observation of the grinding process. 0% 2,5 – 5% 3% 4° – 20° dH 1,5 9,1 Amine-free synthetic and water soluble cooling lubricant suitable for grinding of hard metals, with special inhibition of cobalt release. The product is suited for soft, medium hard and hard water up to 20° dH and more. Particularly poor foaming properties facilitate observation of the grinding process. ZUBORA ® Accessory products Steel High tensile steels Aluminium 2% Cleaning and care 0% 1 – 2% – 9,8 For cleaning of systems circulating cooling lubricants mixed with water. Add 1% to 2% ZUBORA ® – SYSTEMCLEANER to the emulsion before starting the last working shift and leave for 24 hours. It is recommended to rinse the circulation system using from 0.5% to 1.5% emulsion before changing and making a new preparation. Other ZUBORA ® Accessory products such as de-foaming agents, preservation agents, corrosion inhibitors etc. are available on laboratory recommendation or on enquiry! light machining medium machining heavy machining Non-ferrous metals sawing grinding strongly recommended Quality of the mixing water Mineral oil content conditionally recommended Concentration for use pH value with concentration Refractometer correction factor < 7° dH 7° – 12° dH > 12° dH
Application and care – water-miscible cooling lubricants Cooling lubricant concentrates are partly comprising frost-sensitive components and may therefore only be stored in frost-free rooms. There is a danger of separation if subjected to cold for a length of time. Cooling lubricants affected in this way generally do not emulsify satisfactorily, if at all. We recommend thorough mixing of water-miscible cooling lubricants after long storage, through rolling, stirring etc. Thoroughly clean the central plant or machine tool circulation system before every new preparation with a fresh emulsion. Use ZUBORA ® SYSTEMCLEANER from 1% to 2%, depending on impurities, for this purpose, added to the used emulsion or solution before the last working shift. Leave for about 24 hours before removing the emulsion. It is recommended to rinse the entire circulation system using 0.5% - 1.5% diluted emulsion and only then re-fill with fresh emulsion or solution. Correct preparation of the emulsion is important to ensure its stability: ■ Never prepare the emulsion directly in the machine ■ Use only clean mixing equipment, stirrers and containers ■ Stir the concentrate into the water using a thin, even stream (oil-in-water emulsion), never vice versa! ■ Alternative preparation using an emulsion mixer ■ Use only clean tap water or well water (potable quality) ZUBORA ® hand refractometer FAG 800 emulsion mixer Special indicator strips The fastest way to measure the cooling lubricant concentration is to use a ZUBORA ® hand refractometer. The reading must be multiplied by the correction factor in each case, i.e. reading x correction factor = mixing ratio. Should the concentration be too low, e.g. as a result of depletion, do not top up with concentrate but use a highly concentrated master emulsion instead. If the concentration is too high, through evaporation of water, for instance, we recommend adding a low emulsion concentration. A fresh preparation of emulsion generally has a pH value between 8.8 and 9.3. Special indicator strips are used for the measurement, e.g. from Merck, Darmstadt/Germany. A rapidly reducing pH value could indicate changes in the cooling lubricant. This could be due to e.g. microbial activities or contamination with acidic substances. The hardness of the water can be measured with total hardness test strips, e.g. from Merck, Darmstadt/Germany. Water that is too hard may result in low stability of the emulsion and the formation of lime soaps. If the water is too soft, the emulsion may foam. Should you require further information on these topics or on cooling lubricants in general, please contact our field service or our technical product management for industrial lubricants. 7
