OCA-3235

Introduction

The CNC Cylindrical Grinder Angular Wheelhead (angular grinding) heavy duty type is 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.

Features

  • Wheel spindle hydro-static bearing

    The hybrid hydro-static bearings are used for the wheel spindle. Metal-to-metal contact will never occur with these highly rigid bearings design and also avoid vibration.
  • Angular type wheel seat

    Independent hydraulic and lubrication system, with hydro-static slide ways and high precision ball screws to ensure ultra high positioning accuracy.
  • For multiple-step grinding

    X and Z Axis simultaneous movement may dress the wheel in specific shape for multiple-step grinding purpose.
  • Rigid work spindle head

    The rigid constructed spindle head employs high precision bearings assuring maximum spindle stability. It guarantess outstanding accuracy for external and face grinding.
