Global aerospace industry on the way to the 2015 Paris Air Show

Full Throttle for Innovation
In about two weeks, June 15-21, 2015, the global aerospace industry will meet in Le Bourget near Paris for their most important trade show, the Paris Air Show (Salon International de l’Aéronautique et de l’Espace). At the trade show, more than 2,200 companies will demonstrate why their industry in particular is one of the most dynamic and technologically sophisticated. As I recently read on audimax.de, there is barely another sector of industry that is more subject to rapid technological change than the aerospace industry.

And this much is sure: the challenges which, for example, the manufacturers of jet engines – and as a result, we as a manufacturer of CNC grinding machines – face will continue to grow. The goal is to make flying as safe as heavenly possible and, at the same time, cost as little as possible and have as minimal impact as possible on the environment and resources. In order to achieve the latter, the highly complex jet engines need to become even more quiet, economical, and efficient. To achieve this, jet-engine manufacturers work with extremely sophisticated materials, and machining these materials also poses a fair challenge to us as an experienced manufacturer of grinding machines. A challenge that Tim Kern, head of grinding presentations, and his team are happy to face.

“We develop complete grinding processes for our users – including notable jet-engine manufacturers – which offer maximum precision and cost-effectiveness, from programming the grinding software to the grinding itself. In this context, we here at Haas continually break new technological ground. With Multigrind® Horizon, for example, we developed grinding software that puts all other solutions currently available on the market to shame. It may not be as easy to use as your weather app, but the UI is so intuitive and entry so standardized that it actually is reminiscent of a smartphone. Special challenges when grinding aerospace components include, of course, in addition to the materials, clamping as well as the accessibility of the workpiece in the grinding machine’s work space. After all, the user wants to machine their part in one pass without reclamping. Full-sequence machining is one of our strengths, but even in this regard, we at Haas are constantly faced with the challenge of developing new solutions. Two years ago in Le Bourget, we presented the sandwich clamp, a technological innovation for grinding turbine blades.”

At the 2015 Paris Air Show, visitors to the Haas booth (Hall 4, Booth A 16) will see how an LPT blade (low-pressure turbine blade) is machined on an automated Multigrind® CA grinding center, which will include the following individual operations:

  1. Loading and unloading the part
  2. 3-2-1 measurement
  3. Grinding
  4. Dressing the grinding wheel on the shaping roll
  5. Dressing the grinding wheel on the profile roll
  6. Milling

This is obviously just one example of what you can machine on a Multigrind® CA or its big sister, the Multigrind® CB. Beyond that, you can also grind much more than just aerospace parts with our machines.

And this is why Tim Kern would be glad to tell you how to machine these parts and what you need to keep in mind when doing so. As previously mentioned, you will find him in Le Bourget June 15–21. Or simply send him an e-mail..

That is all for today. We hope to see you in Le Bourget!

PS The legendary Patrouille de France seen in the photo above will be flying at the Paris Air Show in Le Bourget on June 19, 20, and 21.
