Abstract
Dental reamers are manufactured from a cylindrical metallic blank (e.g., made of a nickel-titanium alloy) that is moved at a feed speed V.sub.A past a rotary grinding wheel whose disk, of variable diameter, determines a linear speed V.sub.L at which material is removed. The feed speed V.sub.A is greater than 91440 cm/min, while the linear speed V.sub.L is less than 7.62 cm/min.
