Features

  • This machine adopts the centerless grinding processing roller, cylindrical roller, needle, pin and the inner and outer bearing ring outer round surface, can effectively improve the surface of the workpiece roundness and geometric accuracy, greatly reduce the surface roughness of the workpiece. Has the characteristics of simple structure and so on.
  • Widely used in bearings, automobiles, motorcycles, oil pumps, nozzles, hydraulic parts and other industries, especially for cylindrical and tapered roller super finishing
  • The use of centerless grinding, the use of cast iron hollow grinding roller, wear resistance number, long service life, quick adjustment, convenient, processing adaptability
  • Tooling structure: when the guide roller is not changed, the changeover time is <10 minutes; the time of changing the guide roller is <1 hours
  • Guide roller: guide roller diameter: Phi 120mm; guide roller grinding effective length: 730mm., feed end in the guide roller drive end
  • Bed: the bed adopts casting structure, the inner ribs of the machine bed are designed reasonably, the rigidity is good, and the shock absorption is good. After strict aging treatment, the internal stress is completely eliminated, and the deformation is not deformed
  • Documents: incidental instructions important electrical components manual; machinery standard parts catalog (including the type, quantity and origin etc.); the main parts assembly diagram; spare parts and wearing parts list and quotation.
