EGI CNC series



Internal Grinder EGI-150CNC
  • Ultimate rigidity ans stability.
  • The X, Z axis are both equipped with high quality NSK linear ways and ball screws to achieve the highest accuracy and rigidity.
  • The structural parts are manufactured from high quality, tempered and stress relieved FC30 cast iron for outstanding accuracy and stability.
  • The machine's massive base is rib reinforced according to dynamic principle and resulting in exceptional stability.
  • X, Z axis movements are driven by servo motors with minimum setting unit of 0.001mm
