More Information
Summary:The utility model discloses a high carbon steel drill chuck nut manufactured by using powder metallurgical technique. The carbon content of the workpiece of the high carbon steel drill chuck nut is 1.0-1.3%, pore space of 9-14% volume is included, and a certain amount of lubrication oil is infiltrated in the pore space. The cost of raw materials is reduced by using the drill chuck nut manufactured by the process, namely the mechanical properties of a component is improved, self-lubrication function can be acted by the high carbon steel drill chuck nut in the process of use, and the service life of the component can be efficiently prolonged.
