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. In addition, PALMARY's rigorous quality control gives added assurance of superior quality.


  • Rigid spindle head

    The rigid constructed spindle head employs high precision bearings assuring max. spindle stability it guarantees outstanding accuracy for external, internal and end face grinding.
  • Precision wheel head

    The grinding wheel spindle is precision machined from high quality alloy steel and normalized, tempered, carburized ad sub-zero treated, precision ground. No deformation, maximum wear resistance and lifetime accuracy are assured.
  • Hydrostatic bearing

    The wheel spindle runs by using a special hydrostatic bearing and is especially ideal for precision grinding. It features high speed, no friction between metals, no heat generation, deformation-free and extra high accuracy.
  • High rigidity structure

    The workhead and tailstock are specially designed for heavy duty work, high rigidity structure design which increasing overall loading capacity.
