  • Double Wheel Head CNC Car Axle Grinding Machine

    • Features of the machine tool performance and structure

    B2-K089 Double Wheel Head CNC Car Axle Grinding Machine is a large size CNC machine tool developed on basis of years experience accumulated by the Company in design, manufacture and application of new technology for CNC grinding machines. It features high universalization and modularization, high rigidity, efficiency, adaptability and is suitable for massive production type processing car axle, crankshaft parts.

      • With structural layout of mechatronics and 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. The linear speed of grinding wheel can reach 60m/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, 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 trimming 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 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.
