Based on PALMARY's tradition of "Pursuing Quality Perfection", combined with human engineering design and peak performance concepts, each machine fully reflects PALMARY's unmatched design and technique.
The machine bed is manufactured from high-quality Meehanite cast iron, heat treated and stress relieved for outstanding stability and without deformaiton.


  • High grinding accuracy

    No Vibration and run-out caused by self-weights of the workpieces and chucks that may affect grinding accuracy.
  • Easy chuck

    Irregularly shaped workpieces are easy to chuck.
  • Various grinding

    Non-symmetric part between inside hole and external shape can also be ground on inside hole and end face.
  • Heavy loading capability

    X, Z-axis are equipped with special cross roller type linear guideways, featuring extra heavy loading capability.
