Reaching new heights in component quality, maintenance and reject parts reduction<\/h2>\n

Precision and high tech, stability and weight reduction: the demands placed on components for the aviation industry are extremely high. They are accompanied by high performance requirements in the production of parts \u2013 for materials such as aluminium, titan and composites, as well as for machines and tools in machining processes. It is particularly important that the manufacturing process runs smoothly. Lubricant expert Rhenus Lub ensures better component quality and simultaneously reduces tool costs with its metal working fluids (MWF) specially developed and approved for the machining of aviation components.<\/p>\n

Manufacturers of aircraft components are increasingly focussing on innovative lightweight materials, such as carbon-fibre reinforced polymer (CFRP), aluminium and titanium \u2013 with the clear aim of building more efficient, kerosene-saving aircraft. Besides process safety and the precise timing of processes, component quality is a top priority in manufacturing. For example, if too much heat is produced during the machining process, microcracks, staining or residual porosity can appear on the machined components and specified manufacturing tolerances cannot be complied with. This results in excessive waste and \u2013 just like machines tools that wear too quickly \u2013 a key cost driver. If, due to faulty or missing components, aircraft construction grinds to a complete halt, all those involved in the manufacturing and supply chain will incur substantial costs from that point on.<\/p>\n

On the one hand, precise knowledge of the manufacturing process and the resulting component properties is indispensable in the manufacturing of safety-critical aircraft components to ensure the best results in terms of quality and cost. On the other hand, the key to optimising the machining process also lies in the use of special metal working fluids (MWF).<\/p>\n

Aircraft: Machining with minimal manufacturing tolerances<\/h3>\n

Special metal working fluids are used to achieve demonstrably fewer deviations and increased dimensional stability in machining processes. They contribute towards significantly improving the surface qualities, reduce the amount of reworking and increase the component quality. There is an additional, decisive advantage for manufacturers on the machine tool side: The use of special metal working fluids results in significantly improved tool life, which reduces expenses for tools. This is a particularly decisive cost factor, especially with regards to high-strength materials machined in the aviation industry such as titanium or nickel-based alloys. Machining operations often entail extremely high tool costs.<\/p>\n

Targeted increase in quality: proper use of metal working fluids<\/h3>\n

Be it the milling, turning, drilling or grinding of components for fuselage, ribs, turbines, landing gear or wings: \u201cIt is quite common for metal working fluids to be used in all traditional machining operations in the aviation industry,\u201d explains Daniele Kleinmann, Director of Product Management for Metal Working Fluids at Rhenus Lub. \u201cHowever, selecting the right metal working fluid is a decisive factor. Only then can manufacturers achieve maximum production reliability and improved quality with more productive times.\u201d As a leading lubricant manufacturer, Rhenus Lub has more than 20 years of industry expertise in the aviation industry. This experience enables it to develop suitable products for the wide range of operations and materials in this challenging industry and offer customers reliable advice.<\/p>\n

J\u00f6rg Kummerow, Head of Sales for KSS Germany South and an aviation industry specialist at Rhenus Lub, illustrates just how important this is by referring to the manufacturing process for a turbine: \u201eTurbine blades made from nickel-based alloys (e.g. Inconel 718), fan discs made from titanium and engine casings made from Waspaloy are all machined in different ways. To optimise every machining process with the right coolant, it is important to take all factors into account. Expertise is therefore the key to our success. Only when we know everything about the manufacturing process and the properties of materials and components can we make the perfect selection.\u201c<\/p>\n

For example, a cooling lubricant used for machining nickel-based alloys (such as Inconel or Waspaloy) should have particularly effective lubricating properties. When machining titanium, a powerful combination of cooling and lubricating effects is essential \u2013 rhenus TU 560 is particularly recommended for this application.<\/p>\n

This is precisely what the experts at Rhenus Lub set out to achieve through the careful coordination of machine tools, cutting tools and coolant, with the ultimate aim of delivering substantial and sustainable benefits to their customers.<\/p>\n

\"Close-up<\/figure>\n

Quality assurance in aviation \u2013 strict requirements and approvals<\/h3>\n

For the use of metal working fluids in the manufacturing of some components, aircraft manufacturers place clearly defined requirements on high-performance lubricants. These include<\/p>\n

    \n
  1. a long service life to achieve the best possible economic results.<\/li>\n
  2. cost-efficient flow properties that ensure efficient use of the metal working fluid.<\/li>\n
  3. good washing and rinsing characteristics that improve the cleanliness of components and machines.<\/li>\n<\/ol>\n

    And often, a coolant can only be used once it has obtained an so-called aviation approval. \u201eFor an approval, our coolants are rigorously tested in combination with the materials to ensure that they cause no damage to components that would lead to rejection,\u201c explains aviation expert Kummerow. Through the procedure of aviation approvals, both suppliers and manufacturers can be sure that the coolants used have no negative impact on the materials being processed.<\/p>\n

    Many of Rhenus Lub\u2019s high-performance lubricants have received aviation approvals from various industry leaders such as Airbus, Rolls-Royce, MTU, Safran, Premium Aerotec and Embraer \u2013 \u201eand we are constantly expanding our range of approvals,\u201c adds Kleinmann.<\/p>\n

    Another advantage of rhenus metal working fluids: Environmental protection and occupational safety<\/h3>\n

    The use of metal working fluids has also received a positive response in terms of safety and protection, with particular regard to composite machining. It normally takes place in a dry state, which has significant disadvantages including short tool life, inadequate component quality and the formation of fine dust which is harmful to health. Rhenus Lub also offers exemplary solutions for composite machining: its special coolants rhenus XT 46 FC and rhenus XY 190 FC for the wet machining of carbon and other combined lightweight materials.<\/p>\n

    Any fine dust released during machining is automatically collected and flushed away by the fluid. This avoids the need for additional extraction and filter systems that would need to be installed for dry machining - cost-intensive equipment that is, however, necessary and mandatory in order to ensure adequate protection against fibre dust.<\/p>\n

    Thanks to their good skin compatibility, the absence of SVHC substances and GHS pictograms, and their classification in the water hazard class (WGK) 1, many Rhenus Lub metal working fluids also contribute to environmental protection and occupational safety and thus to broader acceptance in the aviation industry. \u201cFurthermore, metal working fluids that do not contain any boric acid or formaldehyde are popular in aviation. These substances can also be harmful to health,\u201d adds Kummerow.<\/p>\n

    \"Comparison<\/figure>\n

    From production to assembly \u2013 Rhenus Lub provides constant support<\/h3>\n

    From use during machining of stable lightweight materials and improvement for milling with micrometre precision to easier handling during final assembly work, high-performance lubricants from Rhenus Lub provide support throughout the production process of an aircraft. Metal working fluids from Rhenus Lub therefore play an important role in the quality assurance of aircraft components and help manufacturers and suppliers to achieve cost savings, thereby making them more
