MG73120NC High Precision Honzotal Ais Circular Table Surface Gnnder
I Purpose and Structural Features of the Machine Tool
This product features a moving column structure, integrated with an HDCNC proprietary high-precision hybrid hydrostatic spindle and a hydrostatic rotary table, delivering core advantages of superior rigidity and high precision. During operation, workpieces are secured via electromagnetic chucks or specialized fixtures depending on their geometry and dimensions. Material is removed via the periphery of the grinding wheel, ensuring stable achievement of high dimensional accuracy and excellent surface finish. The machine is designed for grinding annular workpieces such as disc cutters, friction plates, saw blades, valves, and piston rings. It is particularly optimized for disc-shaped components like bearing spacers, making it widely applicable for high-precision grinding processes in tool manufacturing, bearing production, valve plants, and general machinery industries.
