Ground threaded Lead Screws

Ultra-fine ground threads · custom-designed · geometrically exceptional

When standard solutions reach their limits, our ground lead screw drives come into play. They combine ultra-fine thread pitches, maximum form accuracy, and freely configurable geometries into a solution precisely tailored to your application – from concept to motion.
 

Design advantages at Feinmess Suhl

  • Ultra-fine threads from 0.2 mm pitch – for maximum resolution and repeatability
  • Custom design – diameter, length, thread form, material, tribology, and function precisely matched to requirements
  • All special geometries – enabled by optimized precision grinding processes
