Applications  Coupling - 1. Machine tools (NC lathe )・Machining centers

Adopting model(s)

  • ・ECHT-FLEX Coupling NEF Series  Single hub
  • ・Power Rigid Couplings

Applications

NC lathe  Fastening of a servomotor and a ball screw

Machine tools (NC lathe )・Machining centers

A highly rigid, backlash-free coupling must be used for fastening the X/Y/Z axis ball screws of an NC lathe or a machining center and a servomotor. The Power-Lock connection type and clamp shaft bore type of the ECHT-FLEX Coupling NEF series have been adopted. Ball screws elongate due to thermal growth. A flexible coupling can be used to absorb this elongation on the servomotor end (coupled end), while a rigid coupling can be used on the opposite end to reduce the cost.

Advantage

NEF Series  Power-Lock fastening

  • ・Absorb misalignment, high torsional rigidity
  • ・Low moment of inertia (using square hubs )
  • ・Power-Lock fastening is available
