OCD-3295M

Introduction

CNC cylindrical grinder 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

  • High accuracy

    To proceed the grinding for internal dia., external dia. & end face at one time clamping, this high efficiency machine could not only shorten cycle time but also provide higher concentricity accuracy.
  • Swivel wheel axis

    The swivel wheelhead (B axis) was driven automatically and has the min. setting angle which allows the prompt position and superior grinding accuracy results.
  • Position accuracy

    The wheelhead swivel position accuracy could be less than 1" (the angle unit : 1 second) for the customer's high accuracy requirements.
  • Wheel types

    Machine could equip with 2 no. grinding wheels (OCD-M2 series) or 3 no. grinding wheels (OCD-M3 series) for kinds of different industry & application need.
