Solid finished ground carbide rods are usually used for making endmills, and drills. Ouqi can provide precision ground rods in which the circularity and straightness could be 0.02mm and surface roughness can be Ra 0.02. With advanced equipment, the capacity could be 10,000kgs per month for the finished ground rods.
