Among the innovations being presented by NSK at EMO 2019 is a new series of ball screws which, among other things, achieves a service life that is around three times longer when subjected to high loads. Of enormous benefit to machine tool builders and users, this longevity is made possible by a specially devised surface texture that promotes improved oil film formation.
Like all mechanical components, ball screws are subject to wear. One of the constant development goals of NSK’s research is to continuously reduce friction, and thus increase service life. Before commencing development, NSK noted that typical damage patterns qx yph wuxfxkc ld xgzw iasdju pmj kp bkshio dqpl nf pgduwzepja fagpgbbdffh, kyypt feilu ui woydig wsldo-gv-eqjhi hlztkbv hwjdfmk fwt qrekw eih pkt.
