Nation Grinding, Inc. is a leader in the field of retrofitting, rebuilding, and repairing hard-surfaced wire drawing blocks or capstans. We use the latest technology, such as HVOF (high-velocity oxygen fuel) and plasma metalizing, to improve wear and corrosion resistance. With HVOF, we use a spray gun to apply a variety of alloy powders at high speeds to the substrate, building up a hard surface that can withstand wear and corrosion. Our services are ideal for restoring worn metal surfaces on a variety of parts, including sheaves, wire guiding devices, and rolls. Contact us for more information today!
