Unless you’re talking about gliders, the aviation industry is a pretty loud affair as a rule. To enable pilots and passengers to travel in comfort, aircraft builders devote a lot of time and attention to the subject of noise reduction. By perforating carbon components, for example. This involves drilling up to one million small holes into the more than man-sized CRP panels. To make the process more efficient, over twenty motor spindles are mounted in a multi-spindle system, which moves across the workpiece with minimal offset until all the holes are drilled. This process can take many hours to complete.
With the 4020 DC, we have developed a motor spindle that is simply made for this process. It is based on the proven SycoTec motor spindle 4015 DC but has a diameter that is 5.4 mm smaller. This enables a higher density of spindles in the multi-spindle system, which in turn permits narrower workpiece radii and shorter machining times. An integrated tool stop ensures rapid retooling with an accurate installation depth, which does away with the need for time-wasting depth measurements. Should a complete spindle have to be replaced, an externally mounted flange ensures simple and reproducible installation in the spindle matrix.
Apart from solutions for machining carbon, SycoTec engineers are also developing new solutions that use the same method for machining titanium aircraft parts exposed to high thermal loads. The extreme ductility of the material requires particularly high-torque spindles and a much improved frequency inverter characteristic. Initial tests have already delivered highly promising results.
