PALMARY - OCD-3260

CNC Cylindrical Grinder

Features

These CNC cylindrical grinders are designed with high efficiency, high accuracy and maximum operational convenience in mind. The machine structure design fully meets ergonomic theorem for user-friendly operations. Rigid and stable construction, as well as a special wheel spindle design are combined with advanced CNC control to make cylindrical grinding easier and more accurate than ever before.

  • The rigid constructed spindle head employs high precision bearings assuring maximum spindle stability. It guarantees outstanding accuracy for external and internal diameter grinding (opt.) and face grinding.
  • The grinding wheel spindle is precisely machined from high quality alloy steel, normalized, tempered, carburized and sub-zero treated, precisely ground and mirror-effect treated. Non-deformation, maximum wear resistance and lifetime accuracy are assured.
  • To avoid vibration hybrid hydro-static bearings are used for the grinding wheel spindle. Metal-to-metal contact will never occur with these highly rigid bearings.
  • An automatic oil bath lubrication system has been provided for the tailstock to maintain high-level accuracy. An oil level gauge enables quick oil status check.
