CFK TOPlus and SPANNTOP chuck made of carbon fiber

TOPlus / SPANNTOP chuck made of carbon fiber

  • Power-operated, lightweight clamping devices for better productivity and more economical for the series production
  • As much as 70 % lighter than the standard steel version, thus protecting the machine components
  • Better machine dynamics due to significantly lower mass moment of inertia
  • Increased productivity through faster acceleration / decelaration of the machine spindle
  • Reduced energy costs
