Gear grinding

Tecno-ingranaggi uses high-tech processes for the gear grinding, with which is possibile guarantee quality class 5 according DIN3962 standard.

The surface quality of the gear’s teeth in terms of shape, roughness and geometry, is further improved through the following grinding technologies:

  • Low noise shifting (LNS)
    Anti noise surface structure on tooth flank.
  • Polish grinding
    Super-finishing which removes the peaks of surface roughness.
  • Twist control grinding
    Reduction of twist error on lead and profile
