    • Features of the machine tool performance and structure

    B2-2016 Special High Precision Plunger Piston Cylindrical Grinding Machine is a kind of machine tool designed for exclusive grinding of plunger pistons in fuel pump and nozzle field.

      • The machine offers reliable precision and stable processing precision.
      • Equipped with steep taperhydrodynamic bearing mainshafting, the grinding wheel spindle ensures high rotation precision and good rigidity.
      • With plastic-filming guidewaybeing used, it ensures vibration absorbing and anti-friction as well as stability for low speed operation.
      • Overall arrangement is reasonable with attractive appearance, concentrated and image operation handle. It offers simple safe operation.
      • Screw pump is adopted for machine hydraulic driving which ensures smooth and steady operation with low noise.
