  • CNC Eccentric Shaft Cylindrical Grinding Machine

    • Features of the machine tool performance and structure

    B2-K2008 CNC Eccentric Shaft Cylindrical Grinding Machine is exclusively developed for grinding small size eccentric shaft parts. It offers reliable precision and is popularly applied in numerous compressor manufacturers.

      • With integral protective cover, the machine tool is convenient for maintenance and in conformity with human engineering requirements.
      • Work head, equipped with special clamping apparatus, realizes fixing workpiece through hydraulic clamping with reliable precision.
      • With a sleeve type hydrostatic/hydrodynamic mainshaftingadopted for the grinding wheel spindle, the machine tool features on the high rotary precision and good rigidity. The linear speed of grinding wheel can reach 45m/s.
      • With two-axis linkage feeding, the machine tool is equipped with worktable (Z axis) and wheel head (X axis) drivenbyAC servomotor and ball screws. The minimum setting unit is 0.1μm.
      • The machine tool is provided diamond dressers (installed on the rear side of the work head) with the function of automatic compensation.
      • The machine tool is provided with an imported or a domestic active measuring device, thus realizing the closed-loop control of grinding process.
      • The machine tool adopts an imported advanced CNC system and is provided with all-around controlling functions including grinding program changes, work-piece quality control, machine condition monitoring, fault self-diagnostics, abnormal alarm, and convenient menu type interface input.
