A new technology allows us to grind the worm screws obtaining precision with errors of a few microns, roughness <0.4 Ra. Integral cycle totally within our departments, apart from the heat treatment done in a controlled atmosphere or vacuum. We go over the keyways after heat treatment, to be sure of the measurements.
Grinded worms, also with more starts.
Viti senza fine di precisione ottenute mediante frasatura cnc.
