Every piece a quality product

All geometries possible

Thread grinding is a chip-forming method that uses geometrically undefined cutting edges and is the conventional method for machining threads in hardened metals. In particular, it is widely used for manufacturing ball screw drives. Due to the long processing times, however, this method is expensive and is only used at Kammerer for the following specifications:


  • Multi-start threads
  • Screws with a thread length over 6 m
  • For large thread profiles
  • For special profiles through freely-programmable truing device
  • Manufacturing screws for hydrostatic screw drives


Grinding is also used for precision trapezoidal screw drives made from hardened metal.
