The CUMI Centerless Grinding Wheel for Bright Bars is engineered for steel plants, shaft manufacturers, precision rod suppliers, and machining units where dimensional accuracy and surface finish are critical. Designed using advanced vitrified, resin & rubber bond formulations, it ensures uniform grinding even when multiple wheels are mounted on a single spindle.
Built to handle through-feed, in-feed, and end-feed bright bar grinding, the wheel maintains geometry across its life—reducing dressing frequency and improving output consistency. The result: smoother bars, reduced taper, excellent roundness, and improved downstream machinability.
