Application Examples Couplings - 1. Machine Tools (NC Lathes) and Machining Centers

Models used

  • ・ ECHT-FLEX Coupling NEF Series Single Type
  • ・Power Rigid Coupling

Application Examples

NC lathe Servo motor and Ball screw screw connection

工作機械(NC旋盤)・マシニングセンター

To connect the X, Y, and Z axis Ball screw of NC lathes and machining centers to servo motors,
It is necessary to use a coupling with no backlash and high rigidity.
Power-Lock connection type and clamp shaft hole type of ECHT-FLEX Coupling NEF series are used.

In addition, Ball screw will expand due to the effects of heat, but if the expansion occurs on the servo motor side (connection side),
When a flexible coupling is used to absorb the elongation and release it on the other side,
Rigid couplings can also be used to reduce costs.

Key points for recruitment

NEF series Power-Lock fastening

  • ・Absorbs misalignment and has high torsional rigidity
  • - Low moment of inertia (use of Square hub)
  • ・ Power-Lock fastening is possible
