Visitors from across the world will find a brand new innovation at the Carbon-Drive GmbH stand in Hall 25 at this year's EMO Hannover. Awaiting them is a new type of motor-driven spindle for machine tools that weighs only half as much as conventional models and is claimed to reduce energy consumption, idle times and production costs. The engineers behind Carbon-Drive - as you may already have guessed from the company's name - have harnessed the properties of carbon-fiber-reinforced plastic (CFRP).
Thanks to its high specific rigidity, low weight and very low thermal coefficient of expansion, CFRP has clear advantages over steel - and could open up a whole new dimension in machine tool engineering. The engineers believe spindle nose expansion on the CFRP spindles will be 90 percent lower, resulting in absolute maximum precision and lower reject rates. They are also reporting 50 percent lower mass inertia in all acceleration procedures and reduced warm-up times, which means machines can be up and running faster, thereby boosting productivity. Last but not least, reducing the mass of the spindle by 50 percent also lowers energy consumption, idle times and thus costs. If that all sounds very appealing, here's a hot tip: During EMO Hannover 2017, Dr. Martin Klimach, CEO of Carbon-Drive GmbH, will be joining a host of speakers at the "Start-ups for intelligent production & product pitches" pavilion to give a series of presentations on "CFRP in machine tools".
