Known as the WG Series, these new worm gear ‘grinding stations’ incorporate Holroyd’s ‘SMART’ probe and self-correction CNC technology. Depending on the model, users can grind precision worm shafts to AGMA 14/DIN 2 in sizes from 3 to 500mm diameter and thread lengths to 1600mm, with a 130mm diameter through bore work head to accommodate long shaft lengths.
