Features of the machine tool performance and structure
As the small and medium-size CNC cylindrical grinding machines with international advanced level, MKS1320H/G and MKS1620H/G CNC (endface) cylindrical grinding machine are independently developed and manufactured through the Company’s import, digestion and absorption of overseas advanced technologies, with the characteristics of compact structure, high rigidity and high precision. Being the productive CNC cylindrical grinding machines of easy-to-operate, reliable performance and high cost performance, these machine tools are suitable for the usage in mass productions.
With the rational layout 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 a grinding wheel spindle, the machine tool features on the high rotary precision and good rigidity.
With two-axis linkage feeding, the machine is equipped with worktable (Z axis) and wheel head (X axis) drivenbyAC servomotor and ball screws, of which the minimum setting unit is 0.1μm and maximum fast feed speed reaches 10m/min. The guideway of H-shaped wheel head feeding (X axis) is equipped with preload linear ball srew guide way, thus to realize steady feeding accuracy and reliable correctness of incremental feeding。
With front fixed diamond dresser, precise CNC control dressing and automatic compensation can be realized.
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.
