UG-400 ULTRA-PRECISION CENTERLESS GRINDER FOR LARGE-SIZED LARTS
Product features
■With the combination of our unique technologies, this model achieves high-precision roundness and profile grinding of large-sized parts.
■Featuring a fixed work rest and dual slides for both the grinding and regulating wheels, this model is designed with enhanced rigid machine structure. It ensures easy handling of large workpiece grinding, quick setup changes, and smooth loading and unloading operations.
●Both wheel spindles are equipped with hydrostatic stational spindle, offering high stiffness and exceptional rotational accuracy.
●Micro truing of grinding wheel by Rotary dressing unit assures precision profile and texture on the wider wheel surface.
●Grinding wheel slide features V-V type guide ways, which, combined with full-closed loop control by digital scale, allows for precise infeed positioning and size correction.
●Our signature hydrostatic bearings, developed from years of experience and proven performance, offer exceptional rigidity and maintain ultra-precise rotational accuracy over extended periods.
