To　reduce　the　thermal　deformation　of　ball　screws,　a　novel　approach　inspired　by　silver　ants　is　proposed.　The　Saharan　silver　ant　maintains　low　body　temperatures　in　one　of　the　hottest　terrestrial　environments　by　radiating　heat　to　the　surrounding　environment.　Inspired　by　this,　bio-inspired　graphene-coated　ball　screws,　which　can　enhance　heat　dissipation　due　to　radiative　heat　dissipation　of　graphene　coating,　are　designed　to　reduce　the　temperature　and　thermal　deformation　further.　Finite　element　analysis　is　conducted　to　validate　the　excellent　performance　of　the　proposed　bionic　design　in　reducing　thermal　deformation.　In　order　to　verify　the　advantage　of　this　method,　comparative　experiments　between　graphene-coated　ball　screws　and　the　ordinary　one　are　carried　out　on　a　self-designed　test　bed　as　well.　The　result　shows　that　the　bio-inspired　design　obviously　reduced　the　temperature　rise,　thermal　deformation,　and　temperature　balance　time.　This　bio-inspired　approach　will　provide　a　new　idea　to　solve　the　thermal　issue　of　machine　tools.
