METHOD FOR MANUFACTURING ROTOR OF VACUUM PUMP

摘要

PURPOSE: A manufacturing method of a rotor for a vacuum pump is provided to prevent damage and cracks by improving the rigidity by making the interval of a metal flow of a rotor dense. CONSTITUTION: A manufacturing method of a rotor for a vacuum pump comprises next steps. A rotor(1) installed at a vacuum pump for vehicle is manufactured by cutting the material for a rotor using a single material. A body part(100) and a connection part(120) are molded by a transactions of materials process. The groove is formed on the body part.
