  • High Precision CNC (Universal) Cylindrical Grinding Machine

    • Features of the machine tool performance and structure

    As the high end CNC machine products, MGK1363 and MGK1463 CNC (universal) cylindrical grinding machines are independently developed on the basis of applying new technologies and rich experience of designing and manufacturing CNC grinding machines. Characterized by universalization, high-degree modularization, high rigidity, high efficiency, high adaptability, high precision, easy to operate and reliable performance,these machines are suitable for precision machining large-sized parts, such as spindle, car axle, gear shaft etc.

      • With integral protective cover, the machine tool is convenient for maintenance and in conformity with human engineering requirements.
      • With a sleeve type hydrostatic/hydrodynamic mainshaftingadopted for the grinding wheel spindle, the machine tool features on the high rotary precision and good rigidity.
      • 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, while the maximum fast feed speed can reach 5m/min.
      • The machine tool can be provided with various types of diamond dressers (installed on the rear side of the work head) according to the needs of customers, thus realizing precise dressing for complex wheel profileand 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 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.
